> Claude Code and Claude Console are listed as partially disrupted, while Claude API and Claude services on major cloud platforms are operating normally.

Anthropic is investigating login problems affecting Claude.ai and Claude Code, with Claude.ai marked as experiencing a major outage.

The incident also includes elevated error rates for Claude Code and Claude Console, Anthropic’s platform at platform.claude.com. Both services are listed as partially disrupted, while Claude.ai has the more severe major-outage status. Claude Cowork is included in the incident, but it was already experiencing degraded performance before being added.

Anthropic plans to provide another update as the investigation continues. The current notice did not specify when service would return.

The disruption does not extend to every Claude service. Claude API is listed as operating normally, along with Claude services running on AWS, Google Cloud and Microsoft Foundry. The status differs by product: Claude.ai is in a major outage, Claude Code and Claude Console have partial outages, and Claude Cowork has degraded performance. Users trying to sign in to Claude.ai or Claude Code may encounter problems while Anthropic investigates.
