Every managed service provider promises fast response. The difference between a good and bad experience is in the details: what counts as critical, what "response" actually means, how often targets are met and what you can see.
This guide explains what a cloud managed services SLA should include and the red flags to watch for.
What is an SLA in managed cloud services?
A service level agreement is the part of a managed services contract that defines measurable service commitments: how quickly the provider responds to and resolves incidents, what availability targets apply, coverage hours, reporting and remedies for missed targets.
How should incident priorities be defined?
Clear priority definitions prevent disputes. A typical model:
| Priority | Definition | Example |
|---|---|---|
| P1 – Critical | Production down or severe business impact, no workaround | Customer-facing app unavailable |
| P2 – High/Moderate | Significant degradation or partial outage, workaround may exist | Slow checkout, one region affected |
| P3 – Low | Minor issue, limited impact | Non-production issue, cosmetic error |
| P4 / Request | Service request or question | New user access, configuration change |
Agree who sets priority and how it can be escalated.
What is the difference between response and resolution time?
- Response time: how quickly a qualified engineer acknowledges and starts working the incident.
- Resolution time: how quickly service is restored or a workaround is in place.
Both matter. A fast response with slow resolution still leaves you down. Clarify whether resolution means full fix or service restoration, and how time is counted when waiting for your input.
A fast response with slow resolution still leaves you down.
What should an SLA include?
- Priority definitions with examples
- Response and resolution targets per priority
- Coverage hours (24/7 vs business hours) per service
- Availability targets for services the MSP fully controls
- Escalation matrix with names and roles
- Communication cadence during incidents (for example, P1 updates every 30 minutes)
- Reporting: monthly SLA attainment, incident trends, root causes
- Service credits or remedies for missed targets
- Exclusions: what is not covered, such as third-party outages
- Review process for changing SLAs as the environment evolves
What do good SLA numbers look like?
Here is Crozaint's published SLA as a reference point:
| Priority | Response time | Resolution time |
|---|---|---|
| P1 (Critical) | 30 minutes | 8 hours |
| P2 (Moderate) | 30 minutes | 12 hours |
| P3 (Low) | 1 hour | 36 hours |
Crozaint targets SLA attainment of up to 98% and reported 99.98% uptime over a recent 30-day period.
What are the SLA red flags?
- Response time defined as an automated acknowledgement
- No resolution targets at all
- Vague priority definitions that let the provider downgrade incidents
- "24/7" that only covers P1 out of hours, without saying so
- No monthly reporting on actual attainment
- Uptime commitments for systems the MSP does not control
How do SLAs relate to SLOs?
SLAs are contractual promises; SLOs are internal reliability targets. A mature MSP tracks internal SLOs stricter than the SLA, so it acts before contractual commitments are at risk.
How Crozaint approaches SLAs
Crozaint's managed services run on an ITIL-based service model with a defined escalation matrix and 24/7 operations. Our SLAs are published openly, including 30-minute response for P1 and P2, and we report on SLA attainment and uptime so you can see performance, not just promises. Our dashboards show open incidents and their SLA status in real time.
Common mistakes to avoid
- Signing an SLA without priority examples
- Ignoring resolution times
- Not asking for monthly attainment reports
- Accepting uptime promises for systems outside the MSP's control
- Never reviewing SLAs as the environment changes
Conclusion
The best SLA is specific, measurable and reported every month. Define priorities clearly, track response and resolution separately and insist on transparency.
