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?
99.9% uptime permits 0.1% downtime across the year — roughly 8 hours 45 minutes total, or about 43 minutes per month if outages were spread evenly. In practice they rarely are: a single incident can burn most of that annual allowance in one afternoon. Vendors typically measure this against a rolling 12-month or monthly window, and only crossing the threshold triggers a service-credit remedy — staying just above 99.9% owes nothing.
How does that compare to 99.99% uptime?
99.99% ("four nines") caps downtime at about 52 minutes a year, roughly 4 minutes a month — versus 8 hours 45 minutes for 99.9%. That single extra "9" cuts the permitted outage budget by roughly 90%, around 7 hours 53 minutes less unplanned downtime annually. For a DAM feeding live campaign assets or e-commerce catalogs on a deadline, that gap is the difference between a brief blip and an outage that stalls an entire launch window.
What does an uptime SLA typically cover, and what does it exclude?
Coverage is usually narrow: the vendor commits only to platform availability as measured by a basic health check responding on schedule. Common exclusions include scheduled maintenance windows, API latency, degraded search performance, and outages caused by third-party or CDN failures — even when they make the DAM unusable. Because these exclusions are exactly where real-world incidents concentrate, the fine print defining "downtime" matters more than the headline percentage itself.
What remedy does a vendor usually owe if it misses its SLA?
Almost always a service credit applied against a future invoice, not cash compensation — typically a percentage discount that scales with how far the vendor fell below its committed uptime tier. Credits are usually capped, require the customer to file a claim within a set window, and often exclude the same categories — scheduled maintenance, degraded performance — from the downtime calculation, so the effective payout for a real outage can be smaller than the headline SLA suggests.
What's the mistake buyers make comparing SLA percentages across vendors?
Buyers line up headline numbers — 99.9% versus 99.95% versus 99.99% — without reading how each contract defines "downtime." One vendor's 99.9% might exclude scheduled maintenance and degraded-but-not-fully-down performance entirely, while another counts them; the vendor with the lower advertised percentage can end up more reliable in practice. The exclusions are exactly where most real-world outages happen, so comparing percentages alone tells buyers almost nothing.
Why can a DAM be technically "up" under its SLA while still unusable?
Most SLAs define availability through a basic health check — the server responds, so the platform counts as "up." That check says nothing about whether search is timing out, thumbnail generation is stalled, uploads are failing, or an API feed into a PIM or e-commerce site is degraded. A DAM can pass every health check in its SLA all day while creative teams sit unable to find or upload a single asset.
