"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. AWS and Microsoft Azure publish no machine-readable archive, so their numbers cover only our own tracking window — a shorter period than the others. 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. Live status: AWS · Microsoft Azure.
