Anthropic’s Claude AI Back Online After 90-Minute Global Outage

Anthropic experienced a multi-model outage on June 22, 2026 that began at 00:37 UTC and affected five Claude models (Opus 4.8, Opus 4.7, Opus 4.6, Sonnet 4.6, Haiku 4.5) along with Claude.ai, the Claude API, Claude Code, and Claude Cowork; engineers identified a root cause by 01:11 UTC and rolled out a staged fix with full resolution declared at 02:06 UTC. The roughly 90-minute disruption disrupted developer workflows and followed two prior outages in June, but the report contains no indication of malicious activity or data compromise.
