How is uptime calculated?
Every minute, independent probes on Cloudflare's edge exercise each service the way your browser does: loading pages, signing in, reading data, opening live and collaborative connections and fetching files. A failed check is re-tested immediately, and a service is only marked degraded or down after two consecutive failing minutes. Uptime is the share of monitored minutes in which a service was not down; scheduled maintenance is excluded. Corrections made after an investigation are shown as adjusted days.
