Claude uptime and downtime by month
Claude uptime and downtime per component, month by month — counted only inside recorded incidents, never as an aggregate service figure.
How much downtime has Claude had this month?
September 2026 is still open: 11 recorded incidents so far, counted per component. The figure moves until the month closes.

July 2026 has no page: our archive starts on July 14, 2026, mid-month, so any figure for it would be false.
How this is counted
- Source. Anthropic's public incident reporting for Claude. We do not probe, ping or measure the services ourselves, so nothing here is an availability measurement.
- What we count. Minutes of the month that fell inside a recorded incident window for that component — from the reported start to the reported resolution, clipped to the month.
- What we do not count. Severity is ignored: an incident logged as degraded performance counts the same as a full outage. Unreported disruption, regional differences and per-user impact are invisible to us. An incident window is not the same thing as downtime.
- Overlaps. Figures are per component only, never aggregated into one service-level number. Within a component, overlapping incidents count the shared minutes once; the same minute can appear under several components when an incident affected several.
