On March 2, 2026 , Claude (claude.ai), a popular chatbot from the artificial intelligence company Anthropic, experienced a large-scale service outage affecting multiple regions worldwide. According to data from Anthropic's official status page (status.claude.com) and the monitoring website Downdetector, thousands of users reported issues such as being unable to log in, submission failures, or HTTP 500 errors. The incident is still under investigation.
Event time and official response
The issue was interrupted at approximately 6:49 AM Eastern Time (11:49 AM UTC, 7:49 PM Beijing Time) and officially marked as "Investigating." Anthropic subsequently updated at 12:06 PM UTC, stating that they were "continuing to investigate this issue," and released a key statement at 12:21 PM UTC (approximately 8:21 PM Beijing Time):
"We have confirmed that the Claude API is working properly. The issues we are currently seeing are concentrated on the claude.ai web page and the login/logout paths."
The official statement emphasizes that developers can continue to access Claude models normally via API keys, but the web version, console (platform.claude.com), Claude Code, and other front-end and 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 reported peak numbers in the thousands, with common user symptoms including:
- Automatic logout or inability to log in
- The message "Claude will return soon" appeared.
- Connection interrupted, 500 internal server error
- Submission failed.
Numerous discussions have emerged on social media platforms such as Reddit and X (formerly Twitter), impacting users across North America, Europe, India, Africa, and other regions, indicating that this is a global rather than a regional event. Many users who rely on Claude for work or study reported a significant impact on their productivity, with some switching to other AI tools as temporary alternatives.
