Claudestatus history & uptime
How reliable has Claudebeen? We record a status check every few minutes and keep the history — uptime, recent incidents, and the upstream providers whose outages cascade here. We never invent numbers; where we're still collecting, we say so.
Uptime & history
Tracking since Jun 22, 2026% of our checks that found Claude fully operational — a degraded check counts against it, because a slow or partly-broken service is not a working one. Down and degraded time are counted at our 5-minute check resolution, so both are approximate. Longer windows fill in as data accrues — we never show uptime we haven't measured.

What cascades to Claude
Claude is built on one provider. When one of these has an incident, Claude often degrades too — frequently before its own status page admits it.
History is recorded from Claude's official status plus our own independent checks. AIDownCheck is independent and not affiliated with Anthropic.
