What a 15-Minute SLA Actually Means (And Why It Matters)

Service Level Agreements are where IT marketing goes to get honest. “World-class support” costs nothing to say; “15-minute response to critical incidents, credited against your invoice if we miss” costs real money to operate. When you evaluate any provider — including us — the SLA is the document that tells you what they actually believe about themselves.

Response vs. resolution: the oldest trick

A 15-minute response SLA means a qualified human is engaged with your critical issue within 15 minutes — not that it's fixed. That's fair; no honest engineer promises resolution times for unknown problems. The trick to watch for is providers who let an auto-acknowledgment email count as “response.” Ask directly: does the clock stop when a human starts working, or when a robot sends a receipt?

Severity levels do the heavy lifting

The second thing to read is who defines severity. If the provider unilaterally classifies incidents, everything becomes Priority 3. A good SLA defines severity by business impact — “revenue-generating system down” or “more than 25% of staff unable to work” — in language both sides can point to during the incident, not after it.

Penalties are the proof

Finally: what happens when they miss? Service credits aren't about recouping money — the credit for a missed SLA is usually small. They matter because a provider who accepts automatic penalties has built operations they trust. A provider who won't put teeth in the agreement is telling you their real confidence level, in writing.

Our standard: 15-minute response on critical incidents, 24/7, severity defined by business impact, credits applied automatically. We publish it because we can operate it — and because asking every provider for the same paragraph is the fastest vendor filter we know.
