Most months your host hits the number. The catch is the bad months: when an outage happens, the host's status page often lags the incident by minutes to hours (AWS's own post-mortem on the December 7, 2021 us-east-1 outage admits a 52-minute gap), and every major SLA (AWS, Vercel, Cloudflare, Kinsta, WPEngine) requires you to file a credit claim with your own evidence within a tight window. The fix is independent monitoring that runs from outside your host's network, captures timestamps and response codes during the incident, and gives you the evidence the SLA requires. Velprove's free plan covers HTTP monitoring across 5 regions plus a browser login monitor at no cost. ** What 99.9% uptime actually means The math is settled and primary-sourced.…
