Anthropic’s Claude AI is experiencing a significant service disruption on March 2, 2026, leaving many users unable to access the chatbot due to technical difficulties, including failed login attempts and intermittent service blackouts.
The technical issues began early Monday morning, with data from Downdetector showing a sharp increase in user complaints starting around 12:00 PM UTC. At its peak, the platform recorded nearly 2,000 active reports within a narrow timeframe. Statistics suggest that the web-based chat interface is the hardest hit, with roughly 42% of users reporting issues there, while 34% have noted problems with the mobile application. Many users currently see a notification stating that Claude is experiencing a temporary disruption and will return shortly.
Anthropic has provided ongoing updates via its official status page, outlining the steps taken to resolve the incident. The timeline of the investigation is as follows: at 11:49 UTC, Anthropic acknowledges elevated error rates across claude.ai and associated developer tools. By 12:21 UTC, the team clarifies that while the core Claude API remains stable, the primary web interface and login/logout mechanisms are failing. At 13:22 UTC, the root cause is officially identified, and engineering teams begin deploying a fix for front-end services.
While the outage is significant, it is currently classified as a “partial” disruption. Anthropic confirmed that the Claude API (api.anthropic.com) remains fully operational. This is good news for developers who integrate Claude into third-party apps, as these services should remain unaffected. However, the Claude Console and the specialized Claude Code terminal tool are both experiencing errors, which may stall professional development workflows and coding tasks.
The current downtime appears to be a bottleneck in the authentication and login infrastructure rather than a failure of the AI models themselves. This explains why users already in an active session might see “Internal Server Errors” (such as HTTP 500 or 529), while new users are blocked from entering the site. This incident follows a smaller disruption on February 28 involving the Claude Opus 4.6 model, hinting at the infrastructure strain caused by a rapidly expanding user base.
If you are trying to determine if Claude is down in your specific area, you can stay updated through these channels: the official status page at status.claude.com provides the most direct technical updates, and community hubs like the r/ClaudeAI subreddit and Downdetector offer real-time feedback from other users facing similar issues.
Anthropic’s engineers are currently working on a resolution. While there is no official “Estimated Time of Recovery” yet, users are encouraged to wait for the status page to return to “Operational” status before attempting to log back in or run complex prompts.
