Anthropic's Claude services ran into trouble on Thursday, with users reporting a wave of errors across the company's consumer chatbot, developer console and coding tool. The company said it was investigating the problem.
In a status notice, Anthropic said it was looking into "issues authenticating on Claude.ai and Claude Code" and would provide updates as soon as possible. The disruption also reached the Claude Console at platform.claude.com and Claude Cowork, according to the Claude Status page.
The incident touches several of Anthropic's flagship products at once, spanning its web chat interface, the API platform businesses use to build on its models, and its agentic coding offering. Authentication failures are particularly disruptive because they block access at the front door, leaving users unable to reach any downstream tools even when the underlying models are running normally.

The company did not say how many users were affected, what caused the failures or when service might be fully restored. No timeline for a fix was provided.
The outage lands at a busy stretch for Anthropic. The company has been rolling out new collaboration and agent products, including a beta of Claude Meetings that lets the assistant sit in on video calls to take notes and draft documents, and a private beta of self-hosted Claude Managed Agents aimed at companies that want to run agent workloads inside their own infrastructure. Both efforts lean on the same account and authentication systems that were reported failing on Thursday.
For enterprise customers, the timing is awkward. Teams that have wired Claude into development pipelines, alert triage or meeting workflows depend on steady access to the platform, and authentication outages can stall work even briefly. The status page is the primary channel Anthropic uses to communicate with those customers during incidents, and the company has not yet posted a root-cause explanation.
Anthropic's status page continued to list the issue as under investigation. Further updates are expected as engineers work on the problem.
