What Is CMS Uptime and How Do You Ensure It?
BeginnerQuick Answer
TL;DR
CMS uptime is the percentage of time a content management system is available and responding to requests. Enterprise SLAs range from 99.9% (8.7 hours of downtime per year) to 99.99% (52 minutes per year). Ensure high uptime by choosing a vendor with a strong SLA, implementing CDN caching so your site survives API outages, and using stale-while-revalidate patterns as a fallback.
Key Takeaways
- 99.9% uptime = 8.7 hours of downtime per year; 99.99% = 52 minutes per year
- CDN caching means your site can stay live even if the CMS API goes down
- Stale-while-revalidate (SWR) serves cached content during API outages
- Review SLA terms carefully — "uptime" definitions vary between vendors
