Anthropic's Claude AI models, specifically impacting Claude Code, suffered a major outage today, resulting in 500 errors for developers attempting to use the service. Anthropic acknowledged elevated error rates across all Claude model APIs, quickly identified the root cause, and implemented a fix within about 20 minutes. This downtime forced developers who rely on Claude Code, including teams at Microsoft, to wait for the service restoration. This incident follows other recent issues for Anthropic, including errors with Claude Opus 4.5 yesterday and purchasing problems with its AI credits system earlier this week. The outage for Claude Code, a widely used developer tool, was considered unusual.
