What to do next

Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.
Watch the provider going forward. Follow Anthropic's status feed →

GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
