On Wednesday, Anthropic's Claude AI faced a significant outage, impacting nearly 8,000 users across the United States due to a 500 API error. Users reported issues with the web interface, Claude Code, and related services. Anthropic acknowledged the problem on its server status page and stated that a fix is being implemented. In the meantime, users are encouraged to check the official status page, refresh their sessions, and clear their browser cache as troubleshooting steps. Additionally, Yahoo reported a brief outage affecting its mail and AOL services, with at least 2,000 reports noted on Downdetector. While the number of Yahoo issues has since decreased, Anthropic has not provided an estimated time for full resolution of the Claude AI outage, although past incidents have typically been resolved within 2 to 10 hours.
