"Uptime" = not reporting an incident on the official status page; incident history from each provider's published archive plus our live tracking since May 22, 2026. Reported numbers understate real-world impact — providers acknowledge incidents late and close them early — but they understate it for everyone equally, which is what makes the comparison fair.
