Claude down: login problems hit Claude.ai and Claude Code

What has Anthropic said about the Claude outage?

Anthropic reacted on its service status page. At 10:58 Paris time it wrote: "We are investigating an issue affecting user authentication to Claude.ai and Claude Code. We will provide an update as soon as possible."

The incident page also lists the developer console, found at platform.claude.com, and Claude Cowork among the affected services. So this isn't limited to the chatbot in your browser. Developers who use Claude Code or the console are caught too.

Anthropic has not said what caused the problem, and it has given no estimate for a return to normal.

A rough day for big tech services

Claude isn't alone today. Microsoft is still dealing with a global outage that affects its Outlook email and some Microsoft 365 services. Two unrelated failures on the same Friday make for an awkward morning for anyone whose work depends on the cloud.

For now, the only thing to do is wait and check Anthropic's status page for updates. Since the fault concerns authentication, in other words the step where the service confirms who you are, people who were already signed in may fare differently from those trying to log in fresh, but the source doesn't say so, and Anthropic hasn't commented on that.
