Claude was degraded twice on 13 November, according to Anthropic's own status page. A sign-in problem hit claude.ai, Claude Code and platform.claude.com from 09:58 UTC until 11:58 UTC, and a second incident hit claude.ai, the API and Claude Code from 13:09 UTC until 15:38 UTC.

The second incident reached connectors, Claude in Meetings, Managed Agents and Claude Security as well. Anthropic's 15:33 UTC update said scheduled tasks and routines had run more than two hours late, with some runs skipped.

Separately, the Microsoft 365 connector, which handles mail, calendar, SharePoint and Teams chat, had been failing since 17:52 UTC on 12 November. Anthropic's status page says the cause was a Microsoft 365 service incident, and by 15:40 UTC on 13 November it reported signs of recovery with the Microsoft incident still open.
