Anthropic's Claude AI Platform Experiences Multiple Service Disruptions and Technical Issues

In April 2026, Anthropic's Claude AI platform faced several technical issues that impacted multiple services. The Claude API was fully restored at 8:01 PT on April 10, 2026, after login problems on Claude.ai and Claude Code persisted from 15:31 to 16:19 UTC. An outage for Opus 4.6 occurred from 23:03 PT to 00:26 PT, while Sonnet 4.6 showed increased error rates between 23:00 PT and 1:50 PT. Email login issues were reported from around 3:46 PM to 4:52 PM PDT on April 10, 2026. Additionally, some share links on Claude.ai were unavailable to unsigned users from April 2 to April 10. Authentication problems affected platform.claude.com and the Developer Console from 17:25 to 17:44 UTC. Other components, including Claude for Government and Government Cloud, were also impacted. Workspace creation via the Claude Console and admin API faced disruptions from approximately 4:15 PM to 7:30 PM UTC. Vaults had performance issues, and some users could not start Claude Cowork until the v1.3109.0 release of Claude Desktop resolved the problem. The usage and analytics admin API endpoints experienced intermittent 503 errors, and certain connectors had higher error rates. Voice mode functionality was also disrupted. The platform status page confirmed that all systems were operational after the issues were addressed.
