Overview
- Thousands of users were locked out of Claude after outage reports surged midday on Tuesday, June 2, 2026, with Downdetector and social posts showing a sudden global spike in complaints.
- The disruption hit multiple product surfaces including Claude Chat, mobile and desktop apps, the Claude Console, the Claude API and developer tools such as Claude Code.
- Errors on the Claude API caused third-party integrations and tools that rely on the service to fail, producing a cascade of workflow interruptions for developers and businesses.
- Anthropic posted status updates saying engineers have identified the issue and are deploying a fix, but the company has not yet published detailed root-cause information and some users still see errors.
- The outage produced immediate productivity pain for students, writers and coders and tracked regional surges of reports — for example, India logged over 300 complaints at the peak — and follows smaller model errors reported on June 1 that were resolved quickly.
