What Is A CMS SLA (Service Level Agreement)?
BeginnerQuick Answer
TL;DR
A CMS SLA (Service Level Agreement) is a contractual commitment from a CMS vendor specifying the minimum level of service you can expect — most commonly uptime guarantees (e.g., 99.9%), support response times, and remedies if those commitments aren't met. SLAs matter most for production websites where downtime has direct business impact.
Key Takeaways
- An SLA defines the minimum guaranteed uptime, typically expressed as a percentage (99.9% = ~8.7 hours downtime/year).
- SLAs also cover support response times, incident communication, and compensation for breaches (usually service credits).
- Not all CMS plans include SLAs — they're often reserved for paid or enterprise tiers.
- "Uptime" in an SLA may be defined narrowly — read the fine print to understand what's actually covered.
- SLAs are a floor, not a ceiling — most vendors perform better than their SLA commitments most of the time.
