Claude Services Hit Auth Outage, Resolved in ~2hrs
Original: Elevated errors on claude.ai, Claude Code, and platform.claude.com
Why This Matters
Auth outages hitting all Claude products at once signal single-point-of-failure risk.
Anthropic's Claude.ai, Claude Code, Claude Console, and Claude Cowork all experienced elevated errors on Nov 13, 2026, stemming from an authentication issue. Services were restored within roughly two hours.
Anthropic reported an incident on November 13, 2026 affecting multiple Claude-branded services simultaneously: claude.ai, Claude Code, platform.claude.com (Claude Console), and Claude Cowork. The first public notice went out at 09:58 UTC, citing authentication failures for users attempting to log in. A fix was deployed and announced at 11:05 UTC, with the team monitoring for full recovery. By 11:58 UTC — just two hours after the incident opened — Anthropic marked it resolved. No root cause was disclosed in the public status update beyond the initial description of an authentication issue.
