On March 2, 2026, the popular AI chatbot Claude (claude.ai) from Anthropic experienced a major service disruption affecting multiple regions worldwide. According to Anthropic’s official status page (status.claude.com) and monitoring site Downdetector, thousands of users reported issues such as login failures, prompt submission failures, or HTTP 500 errors. The investigation is ongoing.

Event Timeline and Official Response

The outage was officially marked as “Investigating” at approximately 6:49 AM Eastern Time (11:49 UTC, 19:49 Beijing Time). Anthropic later updated at 12:06 UTC to say they were “continuing to investigate this issue,” and at 12:21 UTC (around 20:21 Beijing Time), issued a key statement:

“We have confirmed that the Claude API is functioning normally. The current issues are focused on the claude.ai web interface, login/logout pathways, and related frontend tools.”

The company emphasized that developers can continue to call the Claude model normally via API keys, but the web interface, platform.claude.com, and Claude Code, along with related tools, are experiencing partial outages. As of the latest update, the issue remains unresolved, and the team is actively investigating the cause.

User Impact and Feedback

Downdetector reports peaked at several thousand reports, with common symptoms including:

• Automatic logout or login failures
• “Claude will return soon” messages
• Connection drops, HTTP 500 internal server errors
• Submission failures

Discussions on Reddit, X (formerly Twitter), and other social platforms are abundant, with affected users spanning North America, Europe, India, Africa, and beyond, indicating this is a global rather than regional event. Many users relying on Claude for work or study reported significant productivity impacts, with some turning to alternative AI tools as temporary substitutes.
