Claude AI Outage Disrupts Login Systems and Coding Tools Globally
Anthropic confirmed global service disruptions on Friday, November 13, 2026, after users reported widespread login failures and access problems across multiple artificial intelligence tools. Software developers and digital workspace users encountered authentication errors affecting Claude.ai, Claude Code, and the Claude API.
Authentication fixes deployed as performance remains degraded for select services.
Anthropic deployed an initial fix for authentication problems that disrupted Claude.ai and Claude Code, marking that specific incident resolved. However, a separate disruption later on Friday impacted several platforms, leaving Claude.ai and Claude Cowork experiencing degraded performance during subsequent status checks. Meanwhile, Claude Code, the Claude API, and the Console returned to operational status. Outage-tracking platform Downdetector recorded a sharp rise in user complaints internationally, including reports originating from India.
The technical difficulties coincided with a widespread Microsoft 365 outage that affected Outlook, Exchange Online, and related enterprise services. Anthropic confirmed that its Microsoft 365 connector suffered interference from the Microsoft service incident, disrupting email, calendar, and search functions operating through Claude integrations, alongside Claude for Outlook. The company maintained that the connector malfunction operated separately from its own authentication and performance incidents.
Regarding regional impact in the Emirates, Anthropic has not issued a UAE-specific advisory regarding the service disruption, leaving the precise extent of user impact in the country unconfirmed. Users tracking recovery efforts can consult the official status dashboard at status.claude.com for real-time updates on affected services.
