Summary
Anthropic is investigating elevated error rates affecting Claude.ai (desktop and mobile apps), Claude Code, Claude Cowork, and the Claude API as of Sep 29, 14:30 UTC. Users are experiencing failed requests, conversation loading/sending errors, and unexpected sign-in prompts; retries may succeed. Platform.claude.com also shows degraded performance. Updates to follow.
Key Points
- Simultaneous outage across Claude.ai, API, Claude Code, and all integrations
- Users report failed requests, conversation errors, and forced re-authentication
- Partial retry success suggests partial recovery or gradual rollout
- platform.claude.com also experiencing degraded performance
- Root cause and ETA undisclosed; incremental updates expected
View developer notes (APIs, breaking changes, migration)
Claude API endpoints experiencing elevated error rates across all regions. Both platform.claude.com and direct claude.ai access impacted; desktop and mobile SDKs affected. Partial success on retries indicates transient failure. Recommend implementing exponential backoff with jitter; ensure timeout and circuit-breaker logic in production. Claude Code IDE and Claude Cowork (collaboration) also down, suggesting backend resource exhaustion or deployment rollback. Root cause and ETA not yet disclosed.
