Anthropic deploys Claude authentication fix… web continues to experience major outage

Anthropic deployed a fix for a Claude authentication issue at 8:05 p.m. on the 13th, but its status page still listed the Claude web service as a major outage at 8:07 p.m., about an hour after the incident was first flagged for investigation at 6:58 p.m. Claude Code and the developer console were reported operating normally, while Claude Cowork showed degraded performance and the Claude API was fully operational. A separate incident affecting the Microsoft 365 connector tool was attributed by Anthropic to a Microsoft service problem. The continued web outage matters because it keeps the consumer-facing entry point to Claude degraded even as developer and API access remain intact; watch for the status page to clear the web service and for any update on the Microsoft 365 connector.
