Should you compare home broadband providers on ping or download speed?

Compare on ping, jitter and packet loss first, and use download speed only to check that the plan is big enough. An online match is a stream of small updates sent back and forth, so how long each one takes, and how steady that is, decides how the game feels. A bigger plan carries more data per second. It does not shorten the trip. Opensignal’s Consistent Quality score reflects this: it combines six indicators, namely download and upload speed, latency, jitter, packet loss and time to first byte (Opensignal: Indonesia fixed broadband experience).

Figure 1 uses Opensignal’s national table for Indonesian fixed broadband, covering fiber, xDSL and cable in the 90 days from 1 January 2026. Biznet Home had the fastest median download (41.0 Mbps) yet ranked sixth for Consistent Quality (54.4%). Indosat HiFi ranked fifth for download (30.9 Mbps) and first for Consistent Quality (69.7%). Icon Plus had the lowest download (17.2 Mbps) and ranked third for consistency (60.5%). Opensignal states that results reflect real user plans and are influenced by plan mix and routers, so this is a signal and not a gaming benchmark. The score also covers HD video and video calls, not gaming alone.

The best result also depends on where you live. Opensignal reports different winners by region: Indosat HiFi leads Consistent Quality, Reliability and Video in Jakarta; XL SATU wins all five awards in Kalimantan, Jawa Barat and Sulawesi; GlobalXtreme wins all five in Bali Nusra; and IndiHome wins in Maluku and Papua, where it is the only ISP operating at scale. A “best provider” page is therefore really a “best provider at this address” page. When a test reads low, here is why speed tests come in below the plan.

The four numbers to compare, and how to check each

The definitions of latency, jitter and bandwidth follow a wireless ISP’s plain-language explainer (Hudson Valley Wireless: Understanding latency, jitter and bandwidth), which also promotes its own service, so we used it for definitions only. Routing is the factor customers see least. Two homes on the same plan can reach the same game region by routes of very different length, which is why a provider’s peering to the game’s region matters as much as its last-mile technology.

Why a “best for gaming” claim needs a definition

Provider rankings often use a gaming score without saying what is in it. A press release by Optimum, a US cable brand, says it won “best gaming experience” in three states using Ookla data, but it does not define the Game Score or say whether jitter and packet loss are included (Business Wire: Optimum and Ookla rankings, January 2025). Treat any such award as marketing until the metric is defined. GFiber, for example, reports a typical latency of 14.8 ms, which it says is 41% better than the US average. That figure is GFiber’s own analysis of Ookla data for the second half of 2025 using a multi-server median, and the post gives no sample size or time-of-day breakdown (GFiber blog). It is a useful example of the kind of number to publish, with the method stated, and not proof about any other network.

How consistent is home broadband for gaming during busy evening hours?

Consistency in the evening depends on how a provider shares capacity and keeps queues short, so ask for evening evidence and not a daily average. Regulators define a peak window for this reason. The FCC measures US performance from 7 to 11pm local time on weeknights, and its report says most subscribers see only slight degradation in speed at peak (FCC Measuring Broadband America, 2023 report). That finding is about speed. The report does not compare peak and off-peak latency, so we found no public peak-hour ping data for Indonesian providers.

Figure 3 is a schematic, not measured data. Two connections on the same plan look identical in the afternoon. One keeps its ping steady through the evening; the other climbs and becomes jittery in the peak window. A daily average would make the second look acceptable, which is why gamers should judge a connection by its worst stretch. Opensignal’s score counts tests across all hours, so a provider with a poor evening shows up as a lower Consistent Quality, but the score does not isolate the evening.

Idle ping flatters a connection

The second trap is load. The FCC reports that latency under downstream load is generally much higher than idle latency, with a larger gap for DSL, and notes that some ISPs have since added active queue management, which improved results after its 2022 testing. In a home, that means a stream or a game update on another device can turn good ping into a laggy match.

On the wireless side, the evening risk is different. A consumer guide published in September 2026 says fixed wireless capacity is shared and “gets thin at 8pm”, and that median speeds can hide a drop in the evening, when heavy users notice it most (PC Tech Magazine). The article is a consumer explainer, gives no magnitude for the drop, and relies on secondhand figures, so read it as a warning to test, not as a measurement.

How to run a fair evening test

1. Plug in. Use an Ethernet cable. NVIDIA recommends a hardwired connection or a 5GHz wireless router, and says 2.4GHz Wi-Fi is not recommended on smart TVs.
2. Pick the right target. Ping the game’s nearest server region, not a speed-test server.
3. Test twice a day. Run a five-minute ping at about 3pm and again between 8 and 10pm.
4. Repeat on three evenings. Record minimum, average and maximum ping, and any packet loss.
5. Add load. Repeat once with a large download running on another device.
6. Compare and report. If only the evening or only the loaded test is bad, send the times to your provider.

This is our suggested method, not a standard. It separates three causes that feel the same in a match.

Is fiber or wireless broadband better for competitive and cloud gaming?

For competitive multiplayer, wired fiber is the safer default, because it showed the lowest and narrowest idle latency in FCC testing and its capacity is not shared across a radio cell. Fixed wireless can work, but its evening consistency has to be proven at your address. For cloud gaming, the limits are set by the service: NVIDIA requires under 80 ms to its data center and recommends under 40 ms, and asks for 15 to 45 Mbps depending on resolution and frame rate (NVIDIA GeForce NOW system requirements).

Figure 5 shows fiber with the lowest and tightest range, cable close behind, and DSL with the widest spread. The FCC measured idle latency to servers near ISP interconnection points using a router-based test, so it describes the access technology, not the route to a particular game. The fixed wireless bar is a claim from a wireless ISP that cites 5 to 15 ms for fixed wireless and 600+ ms for satellite (Hudson Valley Wireless). It is a vendor statement and not a measurement. It does show why wireless should not be ruled out on idle ping alone: the open question is the evening, and the load.

Cloud gaming sets a bandwidth floor and a latency ceiling

Cloud gaming streams video from a data center, so it adds a bandwidth floor to the usual latency question. NVIDIA lists 15 Mbps for 720p at 60 FPS, 25 Mbps for 1080p at 60 FPS, 35 Mbps for streaming up to 1440p or 1600p at 120 FPS, 40 Mbps for 4K at 60 FPS on smart TVs, and 45 Mbps for up to 4K at 120 FPS on Windows PC and macOS Ultimate. It requires under 80 ms latency from an NVIDIA data center and recommends a hardwired connection or a 5GHz wireless router. Pure Xbox reports, citing Microsoft as of April 2025, 10 Mbps on mobile and 20 Mbps on consoles, PCs and tablets, plus 5GHz Wi-Fi or mobile data; check Microsoft’s own support page before you buy.

Large downloads are where plan speed pays off

Game installs are big. NerdZap, a games news site, reports Call of Duty: Modern Warfare III past 200 GB, with some PS5 players reporting about 240 GB, and notes that sizes grow with updates and that the larger figure is player-reported.

Figure 6 is arithmetic: 200 GB is 1,600,000 megabits, divided by the plan speed. Moving from 100 to 300 Mbps cuts a best-case install from about 4 hours 27 minutes to about 1 hour 29 minutes. That is the one part of gaming where a bigger plan helps directly. It does not change your ping, so do not pay for a faster tier to fix lag.

What should you check before you choose a gaming broadband provider, or publish a gaming claim?

Check that the claim names its metric, its time of day, its route and its method. Gamers can use this list to compare providers. Operators and editors can use the same list to review a plan page, a comparison page or an advert.

• Does it name ping, jitter and packet loss, and not only Mbps?
• Does it say where the ping is measured: to which server region, on which test?
• Does it show the evening result, 8 to 10pm, next to the afternoon one?
• Does it say whether the test was wired and idle, or loaded?
• Does it say which technology and which area the figures describe?
• Does it define any gaming score it quotes, and say what is in it?
• Does it separate a measurement from the provider’s own claim?
• Does it state the plan speed needed for the games and cloud services it mentions?
• Does every number carry a date and a source, and who checked it before publication?

Best home broadband for gaming: frequently asked questions

How do you compare fiber providers beyond advertised speed?

Compare how consistently each provider delivers, how reliably it connects, how low its latency is, and how it holds up in the evening, and treat advertised speed as the ceiling. Opensignal measures real user experience and notes that its results do not depend on the plan a customer bought, only on the mix of plans each provider sells and on routers (Opensignal: Indonesia fixed broadband experience). That makes it a better guide to everyday experience than a plan page.

Figure 1 compares two Opensignal reports for the same eight providers. Consistency moved: Biznet Home fell from 57.9% to 54.4%, while IndiHome rose from 53.8% to 57.8%, and XL stayed level at 68.7%. The provider listed as XL Home in the November 2025 report appears as XL SATU in April 2026. The lesson is that a ranking is a snapshot of 90 days. Opensignal also blends fiber, xDSL and cable in these tables, so a provider that sells both fiber and DSL will look different from a pure fiber operator (Opensignal, April 2026).

Figure 2 shows why one number cannot name a winner. In the April 2026 table, Biznet Home ranks first for download (41.0 Mbps) and sixth for Consistent Quality (54.4%). XL SATU ranks first for Reliability. Indosat HiFi ranks first for Consistent Quality, and Oxygen.id ranks first for upload (29.6 Mbps) and for Video. Opensignal publishes a different winner for each award, which is the honest picture: providers are good at different things. Choose the metric that matches how you use the line. For the reliability question behind those scores, see is fiber internet reliable.

The FCC’s latency figures are US idle measurements to servers near ISP interconnection points, from a report that does not compare peak and off-peak latency, so they show the technology and not any one Indonesian provider (FCC 2023 Fixed Measuring Broadband America report). They are still a useful reminder that fiber access usually starts with an advantage that a provider has to keep through its own network and routing. Our suggested home test is simple: use Ethernet, run a speed test and a five-minute ping at about 3pm, repeat between 8 and 10pm on three evenings, and repeat once with a large download running on another device.

Does fiber coverage mean fiber is actually available at your address?

No. “Covered” usually means fiber runs near your home, and connecting your home can still need a survey, permits and a drop cable. The fiber industry separates three states. Homes passed counts premises that fiber runs past, up to a demarcation point such as a pole or chamber. Homes passed plus extends the fiber to the property boundary. Homes connected counts premises that are actively linked and can use services immediately (Emtelle: FTTH insights on homes passed, passed plus and connected). Emtelle is a fiber cable maker, and its page describes common deployment terms, not a standard.

Figure 3 is why the same address can be “covered” on a map and still be weeks from service. Indonesia is still building: the minister put fixed broadband penetration at about 21% of households and offices and set a 50% target for 2029, and a Komdigi director general repeated that fiber should reach 90% of districts (kecamatan) by 2029 (Bisnis.com, 1 October 2025; Bisnis.com, 5 November 2025). TeleGeography, as relayed by Bisnis.com, reports that fiber is nearly 89% of fixed broadband subscribers, so most connections are fiber, but whether it reaches your street is a local question (Bisnis.com, 25 November 2025).

Figure 4 uses Opensignal’s November 2025 report. Rural reliability was lower for the providers it names: IndiHome fell from 318 in urban areas to 240 in rural areas, and Icon Plus from 318 to 256. In rural areas Indosat HiFi led Consistent Quality at 62.4%, while in urban areas XL Home led at 69.0% (Opensignal, November 2025). Bisnis.com framed the same data as Indosat HiFi being strong in villages and Biznet in cities (Bisnis.com, 25 November 2025). The April 2026 report adds regional winners: Indosat HiFi in Jakarta, XL SATU in Kalimantan, Jawa Barat and Sulawesi, GlobalXtreme in Bali Nusra, and IndiHome in Maluku and Papua, where it is the only ISP operating at scale (Opensignal, April 2026). The best provider on paper is therefore the best provider at your address. If you are moving from another line, read how to avoid losing internet when switching providers.

An address check you can run in a day

1. Ask for an address-level check. A postcode or area is not enough.
2. Ask passed or connected. Use the three terms above.
3. Ask about the drop. How long is it, from which pole or chamber, and aerial or underground?
4. Check permissions. Building management, landlord and any road or pole permits.
5. Ask for the timeline and the fallback. How long to install, and what happens, and what you pay, if the survey fails.
6. Ask who maintains the last mile. You want one party responsible for faults.
7. Ask neighbours. Someone on your street on the same provider is the best evidence.

This is our suggested checklist, not a standard. It is deliberately the questions a good provider answers easily.

Which fiber provider offers the best long-term value?

The best long-term value is the lowest total cost over the period you will stay, for a connection that is reliable and can be upgraded, not the lowest monthly price. Total cost is the setup fee plus months multiplied by the monthly price, including any rise after a promotion. Reliability and upgrade options then decide whether that cost buys something you can use. Check the usage terms too: a fair usage policy can change what a plan delivers.

Figure 5 uses three invented offers to show the arithmetic. Offer C has the lowest price in the first year (Rp 200,000), and over 36 months it costs the most, Rp 9.60 million, because its price rises to Rp 300,000. Offer B charges a setup fee, yet comes within Rp 80,000 of offer A. The point is that a setup fee, a promotion and a price rise all change the answer, and none of them is visible in a headline monthly price.

Figure 6 breaks offer C into its parts. Real-world price lists are more complicated than three offers, so the habit to build is simple: ask for the regular price after any promotion, and put it in the calculation. In the United States, the FCC’s broadband labels now require providers to disclose important information about prices, introductory rates and data allowances at the point of sale (FCC: Broadband Labels). We did not find an equivalent Indonesian label requirement in our research, so ask for the same items in writing.

What the provider’s own statements say

Providers do publish useful signals about value, with the caveat that they are marketing. Biznet said in March 2026 that customers still weigh service quality, especially bandwidth, above price, and described plans to raise speeds with no price change, for example from 65 Mbps to 100 Mbps at a fixed Rp 250,000, with a promotion of 100 Mbps at Rp 150,000 a month for three months in parts of Banten (Bisnis.com: Biznet on quality over price). On those numbers the price per Mbps falls from about Rp 3,846 to Rp 2,500. The article also says speeds will rise by “up to 30%” while its example is a 54% increase, so the reported numbers are not fully consistent. Treat it as an example of the question to ask, “will my speed rise at the same price?”, not as a market-wide fact.

What should you check before you choose a fiber provider, or publish a comparison?

Check that the claim is tied to an address, a time of day, a total cost and a source. Households can use this list to compare providers. Operators and editors can use the same list to review a plan page, a comparison article or an advert.

• Does it say whether the address is passed or connected, and when service can start?
• Does it name the metric behind “best”: consistency, reliability, latency or speed?
• Does it show the evening result next to the afternoon one?
• Does it say which technologies the data covers: fiber only, or fiber, xDSL and cable blended?
• Does it say which area the result describes, since city and village results differ?
• Does it show total cost over a stated period, with setup and the post-promotion price?
• Does it explain upgrades, contract length and what happens on early exit?
• Does it separate measurements from the provider’s own claims?
• Does every number carry a date and a source, and who checked it before publication?

Best fiber home broadband provider: frequently asked questions

How do you explain Wi-Fi vs wired speed test results to customers?

The plan is delivered to the router. A phone on Wi-Fi then tests a second link, the wireless one, and that link is usually the weaker of the two. Ofcom’s advice is plain: a wired connection is usually faster and more reliable, and it suggests connecting a device with an Ethernet socket directly to the router when the device does not need to move (Ofcom: Get help with broadband and Wi-Fi problems). That is why a cable test is the first step in any complaint about speed.

The Ookla figure comes from user-run Speedtest.net tests, and ISPreview points out that those tests record no device, room, wall material or distance, so treat 29.8% as a sign of the gap, not a rule. The vendor ranges are for one three-stream Wi-Fi 5 access point and will differ for other equipment.

Why the number on the router box is not a speed

A router sold as 1,750 Mbps adds its two radios together: 450 Mbps on 2.4 GHz and 1,300 Mbps on 5 GHz. A phone uses one band at a time. Most phones have two Wi-Fi streams where the access point has three, which takes the 5 GHz figure to about 867 Mbps (our arithmetic: two thirds of 1,300). Wi-Fi is also half-duplex, so a device sends or receives but not both at the same moment, which the Snapone guide says roughly halves the usable rate. Distance, walls and neighbours then take more. Even the guide’s best-case 400 Mbps is under a quarter of the number on the box.

How do you explain end-to-end speed bottlenecks?

A speed test reports the narrowest point on the whole path between the device and the test server. That point can be in the home, in the shared access network, or at the test server. Cloudflare describes its own result as reflecting “the combined performance of all components along the path to the content”, including local factors such as the browser and Wi-Fi (Cloudflare: How does Cloudflare’s speed test really work?). Customers tend to hear a single number as a verdict on the ISP. It is a verdict on the path. Much of that path is in-home Wi-Fi, which is why the customer experience ends in every room.

In our view, fiber has a lot of headroom, so on a healthy FTTH line the narrowest point is more often in the home or beyond the access network than on the fiber itself. We have no measured share to quote, which is why the test process in the next section matters.

Why two tests on the same line disagree

Test design changes the number. Cloudflare says that, even with the same method, results differ noticeably with the distance to the server, and that how a test ramps up data, how many streams it opens and how it aggregates samples all change outcomes. M-Lab’s NDT uses a single stream because it measures bulk transport capacity more accurately, while a multiple-stream test is less sensitive to spurious packet loss and may mirror the best of its streams (M-Lab: Speed tests, accuracy, NDT and M-Lab). M-Lab also points out that its servers sit outside ISP last-mile networks, so a test crosses the points where ISPs connect to the wider internet, and that, anecdotally, tests hosted inside an ISP network usually read higher.

Congestion and the time of day

M-Lab lists three possible causes for poor performance: Wi-Fi signal problems, congestion inside the ISP’s network, and congestion between ISPs. Ofcom’s codes measure speed at peak times, defined as 8 to 10pm for residential customers, and Ofcom advises customers that speed varies by day and time, so a fuller picture needs more than one test. Telkomsel’s guide for customers says the same in Indonesian: test several times and record results at different times, because morning and night results can differ (Telkomsel: how to test internet speed).

A national figure is not any customer’s plan. Ookla’s August 2026 index puts Indonesia’s fixed broadband median at 51.40 Mbps download, 36.23 Mbps upload and 8 ms latency, 113th globally. Komdigi’s 2026 target is a 45 Mbps average for fixed broadband, up from 37 Mbps in 2025 (Bisnis.com, January 2026). The two figures come from different sources and periods, so do not compare them with each other or with a household’s result.

How do you prove ISP network performance with a standard troubleshooting process?

Use the same wired-first test ladder every time, and write the results down. The step where the number falls tells you whether to look inside the home or at the access network. Ofcom’s customer advice follows the same logic: run a speed test before changing anything, try a few checkers, test at different times, use a cable where practical, check whether one device is slower than the others, and reverse recent changes to the home network.

1. Wire it. Connect one laptop to the router by Ethernet cable and pause other downloads and streams. A cable that cannot carry the plan speed will mislead the test, so use a cable rated for it, as Ofcom advises.
2. Repeat it. Run three tests on two different servers and note the time. A single test is a sample.
3. Test at peak and off-peak. Repeat in the evening, between 8 and 10pm, and again in the morning. Keep the device, the cable and the servers the same.
4. Add Wi-Fi. Test on Wi-Fi next to the router on 5 GHz, then in the room where the problem is felt. Change one thing at a time.
5. Compare and record. Find the step where the number falls. Record date, device, connection, server, download, upload and latency.

Reading the pattern

The results fall into a few recognisable patterns. A cable result near the plan with a low Wi-Fi result points to the home. A cable result that is low at every hour and on every server points to the line or the access side, and justifies a fault ticket. A cable result that falls only in the evening points to congestion. A result that is low on one server and fine on another points to the path or the server. Cloudflare adds one more signal: a gap between idle and loaded latency approaching 100 ms or more over a wired connection suggests the ISP is at fault.

These patterns are a triage guide, not proof. The Notre Dame thesis shows researchers are working on exactly this question, telling a Wi-Fi limit from a broadband bottleneck, and it reports a classifier with 92.4% precision. The abstract gives no sample size and the work is a master’s thesis, so we cite it as a sign the problem is real, not as a method to copy. For a customer conversation, the wired ladder is simpler and easier to explain.

What to do when the pattern points to the ISP

Ofcom says the provider is responsible for fixing faults even if another company owns the network, and asks customers to say when the problem started, whether it is constant or intermittent, and what they have tried. Give support the same fields so the ticket arrives complete. In the UK, voluntary speed codes also set a minimum guaranteed speed and a right to exit if speed regularly falls below it, with measurement at peak times (Comms Ombudsman on the 2019 codes). We did not find a published Indonesian rule on how a residential speed complaint must be tested, so write down your own method and publish it.

A good support script holds to one question, one number and one next step, then points to a reference page for detail. How to Educate Complex Buyers Without Overwhelming Them describes that method for technical buyers, and it works the same way for a customer on the phone.

What should a speed test explanation include before you publish it?

It should say what a test measures, what it cannot measure, and what the customer does next. Use this list to review a help article, a support script, a plan page note or a chatbot answer.

• Does it say the test measures the slowest link on the path, not the plan speed at the router?
• Does it tell the customer to test with a cable first, and say how?
• Does it explain why Wi-Fi results are lower, with distance, band and device as reasons?
• Does it say that server, streams and time of day change the number, and ask for more than one test?
• Does it name the peak window and ask for a test inside and outside it?
• Does it show what the support team will do with each result pattern?
• Does it list what to send to support: time, device, connection, server and results?
• Does every number carry a date and a source, and is there a review date?
• Who writes it, and which network and support owners check it before it goes live?

Speed test results lower than the plan: frequently asked questions

How do you explain availability vs reliability to customers?

Availability is how much of the time the service works. Reliability is how often it fails and how quickly it comes back. A percentage captures the first and hides the second. The AWS Well-Architected framework defines availability as the percentage of time a workload is available for use, meaning it performs its agreed function successfully when required, and gives the formula as available time divided by total time (AWS Well-Architected Reliability pillar). Nothing in that formula records how many separate interruptions made up the lost time. For the customer-facing side of that question, see is fiber internet reliable.

That is the gap customers fall into. Forty-three one-minute drops and one 43-minute outage leave a 30-day month at the same 99.9%, and they are not the same service.

Where reliability comes from: failures and repairs

Availability has two levers. How often things break is the mean time between failures (MTBF). How long repairs take is the mean time to repair (MTTR). AWS gives the estimate as MTBF divided by the sum of MTBF and MTTR, and its worked example, 150 days between failures and a one-hour repair, comes to about 99.97%. Run the same example with a four-hour repair and the result falls to 99.89%, which is about 9.7 hours of downtime a year against 2.4.

For an FTTH operator this is useful because the two levers belong to different teams. Network design and fiber protection affect how often service fails. Field operations, spares, alarms and customer communication affect how long it takes to recover. Telling customers about both makes an SLA sound like a service, not a number.

One practical choice follows. Google measures large distributed services by request success rate, because part of such a service is nearly always serving traffic somewhere (Google SRE book: Embracing Risk). A single customer line has no such cover; when it is down, it is down. In our view time-based measurement is the natural fit for an access line, and it should be reported with outage counts and the longest outage.

How do you translate 99%, 99.9% and 99.99% uptime into real downtime?

Convert every percentage into minutes per month and hours per year, and say which period the SLA measures. Customers cannot picture 99.9%. They can picture 43 minutes. The Google SRE availability table gives the standard conversions, and its note says it assumes no planned downtime.

The table is arithmetic: the share of the period that may be lost. It is not a forecast. Two points change how you present it.

• The period matters. Google Fiber’s business SLA measures monthly uptime. An annual 99.9% allows 8.76 hours, and nothing in the percentage stops those hours falling in one bad day. Say whether your SLA is monthly or annual.
• Planned work may or may not count. The SRE table assumes none. AWS says some customers exclude scheduled maintenance from total time, and advises against it, because users will probably want the service then too. Whatever your contract does, state it.

Why the customer’s line is weaker than any one part

An end-to-end service depends on a chain: the drop and ONT, the OLT and aggregation, the core and upstream links. AWS notes that when each element is a hard dependency, their availabilities multiply. Three good parts at 99.9%, 99.99% and 99.95% give about 99.84%, which is roughly 14 hours of downtime a year, more than 99.9% alone. The values in Figure 4 are illustrative, not measured, but the arithmetic is general: a per-component figure can overstate what the customer receives.

Higher targets also cost more. AWS says tighter availability targets generally need more rigorous testing, automated recovery and operations, and recommends working out the true need before designing for it. That is a useful sentence to give a customer who asks for “five nines” on a residential-grade line.

How do you explain SLA accountability, exclusions and service credits?

Say what is measured, what is excluded, what the customer gets and how it arrives, in that order. A commitment is only as clear as its weakest line. Most SLA disputes start at the exclusions, because that is where the customer’s count of bad minutes and the contract’s count part ways.

What is measured

Define downtime in one sentence. Google Fiber’s Premium SMB SLA defines monthly uptime as total minutes in the month minus downtime minutes, divided by total minutes, and counts downtime only when service is unusable through a total loss of signal (Google Fiber SLA). The consequence is worth saying aloud: a slow connection is not “down” under that definition. If your SLA counts only total loss of service, tell customers so before they find out.

What is excluded

Figure 5 shows why exclusions deserve their own paragraph. In this illustrative month a customer experiences 215 minutes of problems, which would be 99.50% uptime. The contract counts 50 minutes after removing planned work and the customer’s own router fault. That is 99.88%, still below 99.9%, so a credit is due. Exclusions narrow the count; they do not always erase the credit. Showing the arithmetic prevents an argument.

What the customer gets, and how it arrives

Two published designs show the range. Google Fiber’s SLA credits 25% of the monthly recurring charge when uptime falls below 99.9%, capped at that level per month, and applies it automatically to the bill for the second billing cycle after the month, with monthly uptime reports. Ofcom’s UK scheme pays 10.34 pounds for each day a fault stays unrepaired after two working days, paid automatically once the customer has reported the fault, usually as a bill credit within 30 calendar days; it only applies to participating providers, and, as ISPreview notes, the scheme is voluntary (Ofcom).

In Indonesia, the example we found is a pro-rata design after a large event. When the SMPCS 2 cable break disrupted South Papua and Central Papua from 16 August 2025, Telkomsel reported a bill discount for IndiHome and Telkomsel Halo customers matching the length of the service degradation, plus replacement of internet quota that expired during the outage (detikInet, 25 August 2025). We did not find a published national SLA figure for residential FTTH, so state your own terms instead of borrowing a number.

Network planners compare these terms before they take a sales call, and they check what is published. What Network Planners and CTOs Actually Want Before They Take a Sales Call makes that point for fiber vendors generally: publish sourced, checkable material first. An SLA explainer that states the measure, the exclusions and the credit does that.

What should an SLA explanation include before you publish it?

It should answer the customer’s next question before they ask it, and name its sources. Use this list to review a contract summary, a sales page, a support script or a monthly service report.

• Does it give the uptime target and the period it is measured over, monthly or annual?
• Does it convert the percentage into minutes a month and hours a year?
• Does it say that the percentage does not limit how many outages there are?
• Does it define downtime, including whether a slow connection counts?
• Does it list the exclusions, each with its condition, such as notice for planned work?
• Does it show one worked example of counted and excluded minutes?
• Does it state the credit, whether the customer must claim, and when it arrives?
• Does every number carry a date and a source, and is there a review date?
• Who writes it, and which network and legal owners check it before it goes live?

Uptime SLA: frequently asked questions

How do you explain the best router location to customers?

Give customers three rules: central, raised and in the open. Ofcom advises placing the router centrally and off the floor, such as on a shelf, so the signal is not lost to the outside or the ground. The FCC gives the same advice: a central spot, or the room where most online activity happens.

The logic fits in one breath. Wi-Fi spreads outward from the router in every direction. A router in a corner or at the end of a hall sends much of that signal toward the garden and the neighbours, and leaves the far rooms with what is left. Put it in the middle and every room is closer.

Read the numbers together. In some ISPs as much as half of support engagements trace back to home Wi-Fi setups. The 5 GHz band loses range faster than 2.4 GHz even at one metre. Mesh equipment costs real money. Forecasts point to a wave of Wi-Fi 7 hardware, and none of it changes the first rule: the best upgrade is usually a better position. The fiber ends at the ONT, but the customer experience ends in every room.

Height, open space and what sits around the router

Position is more than the room. Ofcom advises keeping the router off the floor and away from radiators and fish tanks, because water, metal and glass block signal. A router inside a cabinet, behind a TV or beside metal shelving is boxed in before the signal leaves the shelf. If the router has external aerials, Ofcom suggests pointing them in different directions, for example one upright and one flat, to improve coverage.

The fiber catch: the best Wi-Fi spot is rarely where the fiber arrives

In many installs the router sits wherever the technician could reach the ONT, which is often where the drop cable enters the home: a hallway by the front door, a utility room, a corner of the garage. That suits the installer and suits Wi-Fi badly. Two answers work. Ask the technician to run a cable from the ONT to a central spot, or use a longer patch cable to move the router once the service is live. Either costs far less than extra equipment, and both are easy to explain in a sentence.

How do you explain walls and signal interference to customers?

Tell customers that every wall takes a bite out of the signal, and that the bite is bigger for dense materials and at 5 GHz. Ofcom says it is usually more difficult to get wifi throughout a house with brick internal walls than one with hollow walls, and that water, metal and glass also block it. Interference is the second problem: other devices and neighbouring networks compete for the same airwaves, mostly at 2.4 GHz.

Signal loss is measured in decibels (dB). Every 10 dB is a tenfold drop in power, and every 3 dB roughly halves it. NHS England’s building guidance lists the transmission loss of common building materials. Light drywall costs about 2.5 dB at 2.4 GHz and 3.5 dB at 5 GHz, so a few plasterboard walls barely register. Heavy concrete costs 22 dB at 2.4 GHz and 44 dB at 5 GHz, which is about 160 times less power at 2.4 GHz and about 25,000 times less at 5 GHz.

The table is a guide, not a survey of your customers’ homes. NHS England also lists stone and brick at 7.7 dB at 5 GHz; its 2.4 GHz entries for brick are unclear, so we leave them out. It lists energy-efficient windows with a metallic coating at 20 to 40 dB, so one window can matter as much as one wall.

Choose the band for the room, not for the label

Do not tell customers that 5 GHz is simply better. The FCC says 2.4 GHz gives broader coverage but slower speeds, while 5 GHz is faster with a shorter range, and it suggests dedicating 5 GHz to the most important uses such as work or school. Ofcom’s 2020 router tests found Wi-Fi performance tends to be better on 5 GHz. Walls cost more at 5 GHz. The practical script is: 5 GHz in the same room or the next one, 2.4 GHz for far rooms and simple devices.

Interference from devices and neighbours

Ofcom lists the usual suspects: microwave ovens, baby monitors, fairy lights and cordless phones can interfere with the router’s signal, so keep the router away from them. The FCC points out that 2.4 GHz is the band many household devices and most Wi-Fi routers share, and suggests checking the router’s settings for other networks in range. Customers rarely connect those dots. Showing the crowd makes it obvious.

Walls and interference are the two honest reasons a good fiber line still gives a weak room. Explain both, and the customer stops hearing “your Wi-Fi is bad” and starts hearing “your Wi-Fi is working against a few specific things we can fix”.

How can you reduce Wi-Fi complaints without upgrading the plan?

Run the free fixes first, in a fixed order, and recommend equipment only when they fail. A faster plan does nothing for a router that is boxed in, and extra equipment is a poor answer to a problem a shelf could solve. A fixed order also keeps every agent giving the same advice. Consistent advice matters because Wi-Fi experience drives FTTH retention as much as price does.

1. Ask where the router sits and which room is slow. Two questions locate most problems before anyone opens an app.
2. Test next to the router, then by cable if possible. The FCC notes that a direct Ethernet connection gives the highest speeds. If the cable result matches the plan, the fiber and the plan are fine.
3. Move the router. Central, raised and in the open, away from radiators, metal and water, as Ofcom advises.
4. Tune the bands. Put important devices on 5 GHz near the router and leave far rooms on 2.4 GHz, as the FCC suggests.
5. Check the noise. Look for microwaves, baby monitors, cordless phones and fairy lights near the router.
6. Only then talk equipment. Ofcom puts powerline adapters from around £20 and mesh starter packs at £60 to over £200.

How do you explain mesh Wi-Fi to customers?

Say that mesh is several small Wi-Fi units working as one network, so the signal is spread through the home instead of coming from one spot. Ofcom describes mesh systems as boxes that connect to your existing router and sit around the home, improving signal strength and coverage without reducing the performance of the broadband connection. It puts starter packs at £60 to over £200, and says larger homes may need more units.

Eliminating Wi-Fi dead zones

A dead zone is a room the router signal cannot reach, and a mesh node is a second source placed to reach it. The node must be able to hear the router well. A node placed inside the dead zone has nothing strong to repeat, which is the most common placement mistake. Put it between the router and the dead zone, in the last spot where the router signal is still strong, then test.

Figure 8 is our summary of common practice, not a standard, so tell customers to follow the app’s signal indicator for their own home. If one node does not cover the room, try moving it before adding another, because every extra wireless unit adds a hop.

Mesh vs traditional Wi-Fi extenders

An extender repeats one router’s signal. A mesh system is managed as one network. Ofcom says boosters, extenders and repeaters amplify the signal and can extend coverage, but unlike mesh they can affect data speeds and how responsive the connection feels. The Wi-Fi Alliance adds a standard: Wi-Fi EasyMesh is a certification that gives multi-unit home networks a controller, which onboards units, sets channels and can suggest that a device move to a better unit, and agents that carry out its commands.

The speed row comes from vendor guidance, so call it indicative. The roaming row is the one customers feel: on a basic extender the phone clings to the first unit until its signal is poor, as Figure 10 shows. Steering works best with devices that support 802.11v, according to the Wi-Fi Alliance, so a mesh system helps most with recent phones and laptops.

Coverage vs speed trade-offs

Every wireless hop between nodes costs speed, and the cost depends on how the nodes are linked. The TP-Link Omada guidance (October 2026) says a single-radio extender can lose about half its usable bandwidth and puts mesh at roughly 50% per wireless hop. A dedicated backhaul radio reduces the penalty rather than eliminating it, and Ethernet between units removes it. Wi-Fi EasyMesh supports both wired and wireless backhaul, and the Wi-Fi Alliance notes that wireless backhaul lets installers place units without running cables.

This is where fiber customers have an advantage. A home with an Ethernet socket near a weak room can use a wired node, and the speed penalty disappears. A home with no sockets can still use wireless nodes, with fewer hops and nodes placed where the router signal is strong. Figure 12 compares the two.

Which advice to give

What should a good Wi-Fi explanation include before you publish it?

It should answer the customer’s next question before they ask it, and name its sources. Use this list to review a help article, an install leaflet or a chatbot script.

• Does it state the router rule in one sentence: central, raised and in the open?
• Does it name the walls, not just “obstacles”, with at least one number a customer can picture?
• Does it separate 2.4 GHz and 5 GHz and say which rooms suit each?
• Does it list the free fixes in order before any equipment?
• Does it show what mesh costs and what wireless links do to speed?
• Does it say when a cable beats another node?
• Does it avoid words that blame the customer, such as wrong, poor or incorrect?
• Does every number carry a date and a source?
• Who writes it, and which engineer checks it before it goes live?

Router placement and mesh Wi-Fi: frequently asked questions

What is a FUP, and why do customers misread it?

A FUP is a rule about heavy use, and customers misread it because the same three letters mean two different things. In the UK, Broadband Genie describes a FUP as a contract term that stops a small number of heavy users slowing the network for everyone else, usually vague and without a stated figure, in contrast to a data cap with a published allowance (Broadband Genie, updated 5 October 2026). In Indonesia, the FUP that customers meet is usually numeric: a published monthly threshold, then a lower speed.

Explain which kind you run. If your policy is a conduct clause, say what “excessive” means in practice. If it is a threshold, state it as a number. A customer who reads “unlimited” on the sales page and discovers a threshold in the terms has met a third thing: a surprise.

Penalties also differ. Broadband Genie lists a warning, a speed restriction for hours or the rest of the month, a move to another package, and in extreme cases cancellation, and notes that the bill payer is responsible for the whole household. The Indonesian policies reported here use a speed step-down only. Say so, because “FUP” without a consequence reads as a threat.

How do you explain usage thresholds and speed changes to customers?

State the threshold in GB, the speed after it, any second step and the reset date, in that order. Customers hear “FUP” as “my internet will be limited”. The accurate version is narrower: nothing changes until usage reaches a stated level, then speed steps down, and it returns when the counter resets. Selular.ID’s January 2026 explainer says exceeding an IndiHome FUP reduces access speed without cutting access, and that service stays active until the billing period ends (Selular.ID, 26 January 2026).

Read the numbers together. A threshold of 1,500 GB sounds large because the customer has no scale for it. Converted to time, it is under three days of a fully used 50 Mbps line, or 50 GB a day. That gives support teams an honest sentence: the policy applies to sustained, heavy use, and a household that streams and browses will usually stay far below it. Test this against your own usage data before you say it.

Bisnis.com reported that IndiHome applies FUP to plans of 10 Mbps and above, counts it monthly, resets it at the start of each month and adds no extra quota after the threshold (Bisnis.com, 14 March 2024). Biznet applied FUP from plans of 50 Mbps and above, with limits that vary by region (Bisnis.com, 16 March 2024), and its CEO said Biznet reviews the limits monthly (Bisnis.com, 21 March 2024). The two designs differ in shape: IndiHome steps down twice and Biznet once, but harder. Neither is wrong, and the explanation must match the shape.

The three questions behind every FUP call

1. “Is my internet being cut?” No. The line stays connected and the speed changes, for the rest of the billing month at most. Say the speed in Mbps.
2. “How much is that threshold, really?” Convert it. 1,200 GB is 40 GB a day, or about 53 hours of a fully used 50 Mbps line. Use one comparison, not three.
3. “Can I pay for more?” Say what is true for your plan. IndiHome’s reported policy adds no extra quota after the threshold, so the options are to wait for the reset, to use less bandwidth-heavy services, or to move to a higher plan (Selular.ID, January 2026).

Keep each answer to one number and one next step. This follows the method in How to Educate Complex Buyers Without Overwhelming Them: one buyer question, one sourced number, one worked example, with the detail on a linked reference page rather than in the call.

How do you state FUP terms clearly to avoid billing disputes?

Put the same six facts on the plan page, the order confirmation and a usage meter, and warn before the threshold, not after it. A billing dispute about FUP is rarely about money. The customer sees a slower connection and an unchanged bill and concludes that the provider has not delivered the plan. The way out is to make the speed change foreseeable.

Regulators in two large markets point the same way. The FCC’s broadband label guidance requires providers to state the data included in a plan and to disclose “any additional charges or reductions in service for any data used in excess” of it (FCC, DA 24-459). In July 2026 the FCC streamlined the label rules, letting sales staff give a verbal summary on the phone, and that summary must still cover the data allowance, according to Davis Wright Tremaine. In the UK, Ofcom says providers must be clear and transparent about their traffic management policy and practices (Ofcom enforcement programme). In an earlier case it said that failing to highlight exceptions to a zero-rated offer “may have been considered as a misleading action or omission” under consumer protection rules (Ofcom, 16 May 2019).

Indonesia leaves the choice to the operator. The ministry said in March 2024 that the government does not set telecom tariffs or FUP strategies, that each operator sets them for its target market, and that it welcomes public complaints about service quality (Bisnis.com, 13 March 2024). Commentators quoted in the same coverage argued that FUP needs transparency because throttling is sometimes not explained up front, and that subscribers who buy a speed tier expect it to hold all month (Bisnis.com, 12 March 2024). Where no rule sets the wording, the operator’s own disclosure is the only safeguard.

The FUP fact box

Six lines cover most of what customers ask. They also map onto the two facts the FCC label asks for: the data included and what happens beyond it. Biznet said its thresholds and speed reductions are published on its website (Bisnis.com, 22 March 2024); the box makes the same content easy to find at the point of sale instead of in the terms.

Wording that prevents the dispute

The “unlimited” row matters because customers compare. Selular.ID reported in June 2026 that MyRepublic says none of its home packages has a FUP, and in March 2024 Bisnis.com reported that Moratelindo planned none and XL Axiata would keep unlimited home internet. One August 2026 article describes Biznet Home as allowing use without quota limits and, in the same text, reminds readers to check the FUP “if applied to certain plans” (Selular.ID, 7 August 2026). A reader cannot tell which plans are affected. Your page should never leave that question open.

We have found no public study that measures how much clear FUP wording reduces disputes, so treat the touchpoints in Figure 3 as good practice drawn from the regulators’ direction, and measure the effect on your own ticket volume.

How do you explain FUP as a balance between network capacity and customer experience?

Say that FUP protects shared capacity, name the number that defines heavy use, and show that ordinary households sit far below it. The reason ISPs give is capacity. Bisnis.com reported that Telkom applies FUP because of unreasonable use by some customers and to keep service quality for the rest (Bisnis.com, 14 March 2024). Biznet said it saw unusually high traffic in some locations, growing each year, and customers reselling the plans they bought; it began applying FUP to some packages in January 2024 (Bisnis.com, 22 March 2024).

The capacity argument is strongest on shared segments at busy hours, and weakest when it is stated as a slogan. Preseem’s subscriber data, from fixed wireless networks, shows why: in March 2024, 27% of subscribers used under 1 GB a day, 23% used over 16 GB a day, and average monthly use was 386 GB, up 17% from the year before (Preseem, 21 March 2024). Use is uneven, and it is growing. Fiber homes can differ, so use this for the shape, not as your own numbers.

Biznet’s CEO put the threshold in household terms: he said 1,500 GB is enough for a family of about four, and that the benefit falls sharply if 10 or more families share one service (Bisnis.com, 21 March 2024). Figure 6 puts that claim next to the data. The thresholds convert to 23 to 50 GB a day, above the 16 GB a day that Preseem calls heavy. A threshold above the heavy line catches the extreme tail rather than the busy quarter, and that is the sentence customers need to hear. Clear limits also protect revenue, as our guide on growing ARPU without increasing churn explains.

Where the criticism is fair

Do not explain FUP as if no one disagrees. An ITB telecommunications policy specialist argued that FUP should be based on field measurements of normal household usage, and that throttling is hard to justify when the stated reason is resale, because resale will continue (Bisnis.com, 12 March 2024). The credible reply is specific: show how the threshold was set, say what it protects, and keep reviewing it as usage grows. Biznet says it reviews its limits monthly; that is the kind of detail that builds trust.

When a customer calls after hitting the threshold

1. Confirm the usage. Open the meter with the customer and read the number back. Do not argue from memory.
2. State the policy in one breath. Threshold, current speed, reset date.
3. Ask what changed. A new streaming box, a cloud backup or a camera upload explains many sudden jumps, and naming it helps the customer fix it.
4. Offer real options. Wait for the reset, use less bandwidth-heavy services, or move to a higher plan, as Selular.ID lists for IndiHome.
5. Record the reason. Repeat contacts show where the policy is unclear, and that is a content fix.

What should a good FUP explanation include before you publish it?

It should answer the customer’s next question before they ask it, and name its sources. Use this list to review a plan page, a welcome message, an alert or an agent script.

• Does it state the threshold in GB, the speed after it and the reset date?
• Does it say whether the internet is cut or the speed changes?
• Does it convert the threshold into something a customer can picture, such as GB a day?
• Does it avoid “unlimited” unless the threshold sits right beside it?
• Does it show where customers check their usage?
• Is there an alert before the threshold, and another when it is reached?
• Does it avoid words that blame the customer, such as abuse or excessive?
• Does every number carry a date and a source, and is there a review date?
• Who writes it, and which network or product owner checks it before it goes live?

Fair usage policy: frequently asked questions

How do you explain shared bandwidth and contention ratio with simple analogies?

Say that the plan speed is the top speed one home can reach, and that the fiber behind it is shared by many homes who are rarely all busy at once. A PON is a shared network: the OLT sends a single stream of downstream traffic that every home on that fiber receives, and bandwidth is commonly shared among its users (Wikipedia: Passive optical network). GPON carries 2.488 Gbit/s downstream, and most deployments split it 1:64, 1:32 or smaller. XGS-PON raises the shared capacity to about 10 Gbit/s and supports up to 1:128.

Figure 1 is the whole idea in one picture. The speeds sold add up to 9,600 Mbps, the shared capacity is 2,488 Mbps, and the ratio is 9,600 divided by 2,488, about 3.9 to 1. That is not a defect. It works because home internet use is bursty: a household streaming a film uses a fraction of its line speed on average, and the moments when many homes ask for the full plan together are short. The number you quote to customers should therefore say what the worst case would be, and what a normal busy evening looks like. Customers often fold this into a wider question, so it helps to know how reliable fiber internet really is.

Why the ratio alone misleads

An engineer at the UK ISP AAISP argues that a contention ratio is a poor measure for three reasons. It ignores link size: two 10:1 links can have very different risk. It ignores usage: a ratio is only meaningful if you know the demand as well. And it can be gamed: a provider selling slow packages looks good on the ratio because the speed side is small. His preferred measure is the average throughput per customer on a link, in Mb/s (AAISP: contention ratios).

Analogies that work, and where each one breaks

Customers grasp sharing through everyday pictures. Each picture also leaves a wrong impression if you stop there, so finish the analogy with the corrective sentence.

How do you explain why broadband speed varies at peak hours?

Say that more homes are online together in the evening, so a shared link can reach capacity and each home’s share can fall. On a well-planned network that dip is small, and a large one is a fault to report. Nokia puts the effect plainly: during busy hours, long-lasting high demand may prevent users from reaching the advertised bitrate on a crowded PON (Nokia: Assure peak bandwidth for broadband subscribers).

The curve in Figure 3 is a schematic, not measured data. It shows the shape that matters: demand follows the day and touches the link’s capacity only for a few evening hours. That is why a monthly average hides the problem and why a speed test at 3pm says little about 9pm. Regulators define the window for this reason. Ofcom reports UK speeds for 8 to 10pm (Ofcom: latest home broadband performance trends), and the FCC measures US performance on weeknights from 7 to 11pm local time (FCC Measuring Broadband America, thirteenth report).

Two readings of Figure 4 belong in any customer explanation. First, a small dip is normal: Ofcom’s peak-time average was about 95% of the average maximum speed, and the FCC found that most subscribers saw only slight degradation from off-peak to peak. Second, the dip is smallest on fiber: Ofcom found the effect of congestion during busy periods was lowest for full-fibre lines. The data does not say that fiber never congests. Four of the FCC’s 12 set-ups reached about 86% to 90% of advertised speed at peak, and individual PONs can run hotter than the average.

Demand spikes are real and sometimes national. Indosat reported more than 20% year-on-year traffic growth during the 2026 Eid homecoming and a government projection of up to 40% growth over Ramadan and Eid, on a mobile network and by the operator’s own account (Meatech Watch on Indosat). The lesson for fiber teams is that peaks can be forecast, so they can be planned for.

To tell the first two patterns apart, ask for a wired test. Ofcom’s customer advice is to test more than once at different times and to use a cable where practical (Ofcom: Get help with broadband and Wi-Fi problems), and Selectra suggests a laptop on Ethernet, three tests ten minutes apart, in the afternoon and in the evening, repeated over three evenings (Selectra: Your fibre line is shared with up to 31 other homes). Selectra is a comparison site, so treat that as practical advice and not a standard.

How do capacity planning and traffic management help ISPs control congestion?

ISPs control congestion by measuring the busy hour on every shared link, adding capacity before a link runs hot, spreading customers across links, and managing how the remaining capacity is shared. The AAISP engineer’s point is that there is no single contention ratio for an ISP, because sharing happens at several layers, from the customer line to the cabinet, backhaul, carrier links, edge routers and transit. Each layer needs its own check.

Two levers that change the worst case

Capacity per home depends on two things an operator controls: how many homes share a PON, and which PON generation carries them. Divide the shared capacity by the homes and the worst case, every home at full demand in the same instant, moves a long way. Figure 6 uses the GPON and XGS-PON rates and split ratios described above. Only XGS-PON at 1:32 covers a 300 Mbps plan even in the worst case, which is one reason operators plan around the busy hour and not the theoretical peak. Selectra reports that Openreach is deploying XGS-PON in the UK, and reads the move as raising shared capacity from 2.5 to 10 Gb/s; that is a comparison-site report and we have not independently verified the rollout figures.

The trade-offs operators face

Nokia describes the trade-off directly. Competitors push advertised rates up, and the traditional response is to raise the overbooking factor so subscribers can reach higher rates without adding capacity, which increases congestion on the PON and reduces peak-rate availability. The opposite fix, fewer subscribers per PON, underuses the network and needs field work to move customers. Nokia’s own answer is a software app that uses machine learning on high-frequency traffic data to improve peak-rate availability on loaded PONs. The article is a vendor post and reports no measured results, so treat it as a description of the problem, not proof that the product works (Nokia blog, November 2022).

Traffic management then decides how what remains is shared. In GPON the OLT hands out upstream transmission opportunities to each customer unit according to its activity and its traffic contract, in priority order from fixed to assured to non-assured to best-effort (IP Infusion: DBA, the GPON upstream bandwidth maestro). The page has no named author or date, so use it as a plain explainer of the mechanism. Customers do not need the mechanism; they need to know that capacity is shared by rule, not by accident.

Operators also report using monitoring to see trouble early. Indosat said it used real-time monitoring and predictive analytics to detect congestion more than 60% faster during Eid 2026, on its mobile network and by its own account. Network planners compare these practices before they take a sales call, and they check what is published. What Network Planners and CTOs Actually Want Before They Take a Sales Call makes that point for fiber vendors generally: evidence first, claims second.

What should a contention ratio explanation include before you publish it?

It should say what is shared, what the worst case is, what a normal evening looks like, and what the customer can do. Use this list to review a plan page, a help article, a support script or a sales answer.

• Does it say the plan speed is the top speed one home can reach, not a guaranteed constant?
• Does it name what is shared, and give the capacity and the number of homes, not only a ratio?
• Does it explain oversubscription as a normal practice, and say when it becomes a problem?
• Does it use one analogy, and add the sentence that stops the analogy misleading?
• Does it name the busy window and say what a normal dip looks like?
• Does it tell the customer how to check: a wired test in the afternoon and the evening?
• Does it say what you measure and what you do when a shared link fills?
• Does it avoid “dedicated” and “no congestion” unless they are true?
• Does every number carry a date and a source, and who checks it before it goes live?
