Anthropic Claude elevated errors, November 13, 2026

Anthropic's Claude services suffered a second, separate outage on November 13, 2026, with elevated errors and degraded performance across claude.ai, the Claude API, and Claude Code. Anthropic opened the incident on its status page at 1:09 PM UTC (8:09 AM Eastern, 5:09 AM Pacific), stating it was investigating reports of degraded performance affecting claude.ai, the Claude API, and Claude Code. On Anthropic's component markings, claude.ai was a major outage, the Claude API and Claude Code were partial outages, and Claude Cowork was degraded; Claude Console and Claude for Government were operational. Unlike the morning login outage on the same day, the Claude API is listed as affected in this incident. The incident is separate from Claude's Microsoft 365 connector incident, which began November 12 and remains open; Anthropic has not linked this incident to Microsoft and has not disclosed a cause for it.

Verified November 13, 2026 at about 8:53-9:00 AM Eastern: Anthropic's official status page read live by Jim Callahan (incident "Elevated errors on claude.ai, Claude API, and Claude Code," investigating from 1:09 PM UTC, latest update 1:52 PM UTC), cross-verified by Pingoru's record of the same incident (ongoing since 1:09 PM UTC, affecting claude.ai, Claude API and Claude Code, with Claude Cowork also listed) and PulsAPI's 1:31 PM UTC status report (partial outage; claude.ai major outage, Claude API partial outage, Claude Code partial outage).

Update, November 13, 2026, 9:23 AM Eastern: Anthropic remains investigating, and its latest update on November 13 (9:03 AM Eastern, 2:03 PM UTC, read live 9:24 to 9:27 AM Eastern) expands the affected surfaces. Anthropic said it is investigating reports of degraded performance affecting a variety of surfaces including claude.ai, the Claude API, Claude Code, connectors including Claude Docs and Claude Sheets, Claude Security, and Claude Managed Agents. Claude Security and Claude Managed Agents are new in this update; the previous 8:52 AM Eastern update had named only the connectors beyond the core services. Component markings are unchanged: claude.ai major outage, Claude API and Claude Code partial outages, Claude Cowork degraded performance, and Claude Console, Claude for Government, and Claude on Cloud Platforms operational. Anthropic has not disclosed a cause, has not linked this incident to Microsoft, and has not stated compensation.

Restoration, November 13, 2026, 10:53 AM Eastern: Anthropic has resolved the elevated-errors incident affecting claude.ai, the Claude API and Claude Code. Anthropic said at 10:33 AM Eastern (3:33 PM UTC) it had deployed a fix and was seeing recovery on claude.ai and the Claude API, that some requests might still fail while recovery continued and errors might return as traffic was restored, and that it was continuing to monitor. Anthropic then said at 10:38 AM Eastern (3:38 PM UTC): the issue affecting multiple surfaces has been resolved. At verification time the Claude API, Claude Code and Claude Console were Operational on Anthropic's status page; claude.ai and Claude Cowork still showed Degraded Performance as components, and the page header still read Degraded Performance, which Anthropic attributes in part to a separate, still-open Microsoft 365 connector incident (Monitoring at 10:40 AM Eastern, with SharePoint search still returning some errors and Microsoft's own incident still open). That connector incident is separate from this incident and remains logged only, as before. Anthropic has disclosed no cause for this incident, has not linked it to Microsoft, and has not stated compensation. Duration from the first Investigating post at 8:09 AM Eastern (1:09 PM UTC) to resolution at 10:38 AM Eastern is 2 hours 29 minutes. Provider-local time is UTC on Anthropic's status page; Eastern times are as above.
