What Is a Service Level Agreement (SLA) and Why Does It Matter for IT Support?

SLAs define what you are actually buying

When you engage an IT support provider, the Service Level Agreement (SLA) is the contractual document that defines what you will get, how fast, and what happens when the provider falls short.

Too many businesses sign IT contracts without understanding the SLA they contain, and only discover the gaps when something goes wrong.

The key metrics in an IT SLA

Response time is how quickly the provider acknowledges your ticket. This is often confused with resolution time, which is when the issue is actually fixed. Make sure both are clearly defined for each priority level.

Priority levels define how the provider categorises incidents. A common framework:

• P1 (Critical): Complete outage, all users affected. Target: acknowledge within 15 minutes, resolve within 4 hours.
• P2 (High): Major service degraded. Acknowledge within 1 hour, resolve within 8 hours.
• P3 (Medium): Single user affected. Acknowledge within 4 hours, resolve within next business day.
• P4 (Low): Minor issue or request. Respond within 1 business day.

Availability/Uptime: For managed servers or cloud services, 99.9% means roughly 8.7 hours of downtime per year. 99.99% means under 53 minutes.

Exclusions: Watch for broad carve-outs such as force majeure, third-party service issues, or outside business hours.
