Uptime SLA
A contractual commitment from a DAM vendor guaranteeing platform availability at a stated percentage, with defined remedies — usually service credits — if it falls short.
Why it matters in a DAM
The gap between 99.9% and 99.99% sounds trivial but is nearly eight extra hours of downtime a year, which matters when a global agency network or e-commerce team depends on the DAM to push live imagery against a hard deadline. Uptime SLA figures typically cover platform availability only — not API latency, search performance, or scheduled maintenance windows — so the exclusions in the contract matter as much as the headline percentage.
A worked example
Common mistake
Buyers compare the headline SLA percentage across vendors without reading what counts as "downtime" in the contract — many exclude scheduled maintenance, degraded-but-not-fully-down performance, or CDN/third-party failures, which is exactly where most real-world outages happen.
An uptime SLA is the specific line in a DAM contract stating how much downtime the vendor is contractually permitted before the customer is owed a remedy, almost always a service credit against the next invoice rather than cash compensation. The percentage is deceptively compact: going from 99.9% to 99.99% availability cuts allowed annual downtime from roughly 8 hours 45 minutes to about 52 minutes — a difference that matters enormously if the DAM is in the critical path for a product launch, but is largely irrelevant for an internal archive used a few times a week.
What the SLA measures is the more important question than what it promises. Most vendor SLAs define availability narrowly — the platform responds to a basic health check — which can be technically “up” while search is timing out, uploads are failing, or API integrations feeding a PIM or e-commerce site are degraded. Scheduled maintenance windows are also commonly excluded from the downtime calculation entirely, which can push real-world unavailability well past what the headline number implies.
For buyers where DAM availability is business-critical, the useful exercise is translating the SLA into a downtime budget in the specific units that matter operationally — minutes per month, not just a percentage — and checking that against how the DAM is actually used: does a campaign launch window ever overlap with the vendor’s stated maintenance schedule, and what happens to in-flight uploads or approvals if the platform drops mid-session.
Frequently asked
How much downtime does 99.9% uptime actually allow per year?
Roughly 8 hours 45 minutes per year, about 43 minutes per month.
How does that compare to 99.99% uptime?
99.99% ("four nines") allows only about 52 minutes of downtime per year, roughly 4 minutes per month — a large practical difference despite the small percentage gap.
What does an uptime SLA typically cover, and what does it exclude?
It typically covers only platform availability via a basic health check, and commonly excludes scheduled maintenance windows, API latency, search performance, or third-party/CDN failures.
What remedy does a vendor usually owe if it misses its SLA?
A service credit against the next invoice, almost never cash compensation.
What's the mistake buyers make comparing SLA percentages across vendors?
Comparing the headline percentage without reading what counts as "downtime" in the contract — exclusions are exactly where most real-world outages happen.
Why can a DAM be technically "up" under its SLA while still unusable?
Because availability is often measured by a basic health check response, which can pass even while search is timing out or uploads are failing.
