Anthropic is actively engaged in deploying a corrective measure to restore full functionality to Claude Code following a significant service interruption.
Earlier today, Anthropic's suite of Claude AI models encountered a major outage, severely affecting critical offerings such as Claude Code. Developers attempting to utilize Claude Code were met with persistent 500 errors, while the company itself acknowledged elevated error rates across its APIs for "all Claude models."
The root cause was swiftly identified by Anthropic, leading to the implementation of a fix within approximately 20 minutes. Despite this rapid response, developers who depend on these tools faced considerable downtime. This incident follows closely on the heels of other recent technical issues, including errors experienced by Claude Opus 4.5 yesterday and earlier purchasing complications within Anthropic's AI credits system this week.
Such a substantial outage for Claude Code is considered uncommon, particularly given its widespread adoption among the developer community, including prominent teams within Microsoft's AI division.
Update, February 3rd: Anthropic has confirmed the successful resolution of its Claude API outage.
