An enterprise video SLA reads like a promise that calls will work. 99.9% uptime sounds like almost never down.

Read the document instead of the number and the promise narrows quickly. Availability might mean API requests that didn't error, or joins that succeeded, measured in five-minute windows. Outages shorter than five minutes may not count at all. Your own peak can be excluded. And the remedy for all of it is usually a credit of around 10% of one month's bill.

We read three published SLAs from companies that sell real-time video, as they appeared on 13 October 2026. This post sets out what they actually commit to, and what to ask for when it matters.

What the Percentage Allows

Start with the arithmetic. Over a 30-day month:

Uptime commitment	Downtime allowed per month
99.99%	4.3 minutes
99.95%	21.6 minutes
99.9%	43.2 minutes
99%	7.2 hours
95%	36 hours

Forty-three minutes is one all-hands. A 99.9% SLA can be met in full by a month in which your single most important meeting failed from start to finish. The percentage says how much failure the vendor accepts, not when it happens.

Three SLAs, Three Definitions of "Available"

What counts as downtime matters more than the percentage, and the three documents define it differently.

	Twilio APIs	Amazon Chime SDK	BytePlus RTC
Top commitment	99.95% (99.99% on Enterprise Edition)	Tiers from 99.99% (top tier needs a Well-Architected Review)	99.9%
What is measured	Minutes the APIs are unavailable	Share of API requests without server errors, per 5-minute interval	Join success rate, per 5-minute interval
What counts as down	Unavailability of 5 minutes or more	Requests that return a 5XX error	Join success below 95% for 5+ minutes, with at least 500 join attempts
Credit	10% of fees for the affected API	10% / 25% / 100% by tier	10% / 25% / 50% by tier
Cap	Not stated	The tier percentages	50% of the monthly fee
Claim window	30 days after the month	End of the second billing cycle	30 days after the month
Remedy	Credits are the sole and exclusive remedy	Credits are the sole and exclusive remedy	Credits are the sole and exclusive remedy

Sources: the Twilio APIs SLA (last updated 9 April 2026), the Amazon Chime SDK SLA (last updated 18 November 2022) and the BytePlus RTC SLA (last updated 18 March 2024). SLAs are revised; check the version in your contract.

BytePlus's definition is the closest to what a user experiences: it measures whether people could join. Chime SDK's measures whether the API calls that create meetings and attendees returned errors. Twilio's measures minutes of unavailability. None of the three measures whether a call, once joined, was any good.

Four Gaps Between the SLA and a Bad Call

Short outages don't count

Twilio excludes unavailability of less than five continuous minutes. BytePlus requires join success below 95% for five minutes or longer. A four-minute failure at 10:00, or three two-minute failures in an hour, can leave the SLA untouched. Real-time video is unusually sensitive to short failures: a call that drops for four minutes is a meeting lost, not a minor blip.

It measures the API, not the call

Chime SDK's availability is built from requests: creating meetings and attendees, starting media pipelines, messaging. If those calls succeed but audio is choppy or video freezes, the SLA sees a healthy service. The same gap exists in reverse during real outages: when Cloudflare's realtime SFU failed in June 2025, calls in progress continued and only new sessions failed. Which side of that split your SLA measures decides whether the incident counts.

Your peak can be excluded

BytePlus excludes high-concurrency events on the customer's side. Chime SDK excludes downtime caused by exceeding service quotas. Both are reasonable from the vendor's side: they can't promise capacity you didn't plan for. But they mean the SLA is weakest at the moment every join arrives at once, which is when an outage costs the most. If your critical events are known peaks, the contract needs to say they are covered, with the quotas to match.

Is video even covered?

Read the product scope before the percentage. Twilio's SLA covers APIs branded "Twilio" without listing Programmable Video by name, a point our post on who gets paged when video fails raised earlier. Twilio also excludes alpha, beta and limited-release APIs. If the feature you depend on is new, it may sit outside the SLA entirely.

What the Credit Is Worth

Take the crossover workload from our pricing analysis: 100 concurrent participants, eight hours a day, 22 days a month, at $0.004 per participant-minute, or $4,224 a month.

Credit tier	Value
10%	$422.40
25%	$1,056
50%	$2,112

A 10% credit on that bill is $422.40, applied to a future invoice, not paid out. It is the same whether the outage hit a quiet Sunday or the board meeting. And it only arrives if you claim it in time, with evidence: AWS asks for the affected five-minute intervals and your request logs, and requires an Enterprise Support plan to be eligible at all. Twilio wants the outage dates and times and supporting documentation within 30 days. Credits below $1 are not issued by AWS.

"Sole and exclusive remedy" closes the loop. All three documents make the credit the only thing you get, which in practice makes it the ceiling on the vendor's liability for downtime.

The counterweight is worth saying plainly. Credits were never meant to compensate you for an outage. They are a signal of how a vendor measures itself and what it is willing to put at risk. A provider with a stricter definition of "available" at 99.9% can be a better bet than one with a loose definition at 99.99%.

What to Ask For Instead

If video is critical, negotiate the definition, not just the number:

Define availability as join success and media delivery, measured from your users' side, not only API errors.
Shorten or remove the five-minute floor for real-time services, or add per-incident credits.
Cover scheduled peaks explicitly, with the quotas and pre-scaling that make them realistic.
Name the products. The SLA should list the video, recording and TURN services you use.
Get incident reports. A written root cause within an agreed time is worth more operationally than the credit.

Then measure it yourself. Alerting on join success rate and collecting call-quality statistics gives you the evidence a claim needs, and the early warning the SLA never will.

If you self-host, there is no vendor SLA at all. The number becomes an internal target, the redundancy behind it is yours to build, and the credit is replaced by your own on-call rota.

The Bottom Line

An enterprise video SLA promises less than its percentage suggests. It defines availability its own way, ignores short outages, can exclude your peaks, may not name video, and pays out a credit of around 10% as the only remedy. Read the definition, negotiate it where video is critical, and keep your own measurements, because the contract won't keep them for you.

What's Next

A contract is only as good as the architecture under it. Next: the redundancy that backs the number, and the other checks an enterprise buyer runs.

Frequently Asked Questions

What does a 99.9% enterprise video SLA allow?

About 43 minutes of downtime in a 30-day month. That is enough for one important meeting to fail completely while the SLA is still met. What counts as downtime depends on the document's own definition.

Do video SLAs cover poor call quality?

Not in the three we read. They measure API errors, unavailable minutes or join success. A call that connects but freezes or drops audio isn't counted as downtime.

How much is an SLA credit worth?

Typically 10% of that month's fees for the affected service at the first tier, applied to future invoices. On a $4,224 monthly bill, that is $422.40. Some SLAs step up to 25%, 50% or 100% for longer outages, and most make the credit your only remedy.

Why don't short outages count against the SLA?

Many SLAs exclude unavailability shorter than five continuous minutes or measure in five-minute windows. For real-time video, where a four-minute drop loses a meeting, ask for a shorter floor or per-incident credits.

What should an enterprise ask for in a video SLA?

Availability defined by join success and media delivery, named products, coverage for scheduled peaks, a shorter outage floor and written incident reports. For deployments where Samvyo runs the platform as a managed service, those are the same questions to put to Samvyo.

Does a self-hosted video platform have an SLA?

Not from a vendor. The uptime target becomes your own, and so does the redundancy behind it. Platforms such as Samvyo, which support on-premise deployment, give you control of the media path, TURN and recording, so availability depends on how you run them.
