On Mon, Mar 2, 2026, Anthropic's AI assistant, Claude, experienced a global outage, affecting users and developers worldwide.
Organizations utilizing the AI for threat intelligence, code generation, and security analysis experienced temporary operational disruptions due to increased error rates.
The incident began at 11:49 UTC, leading Anthropic engineers to investigate user reports of service failures.
The outage affected infrastructure nodes, including the primary claude.ai interface, developer console, and the Claude Code platform . Initially, the core API infrastructure was believed intact. By 12:21 UTC, issues were isolated to web application authentication pathways.
Further analysis revealed expanded outage scope by 13:37 UTC, impacting core API methods and third-party integrations.
Time (UTC) Incident Status Technical Details
11:49 Investigating Initial detection of elevated errors across core Claude services.
On Mon, Mar 2, 2026, Anthropic's AI assistant, Claude, experienced a global outage, affecting users and developers worldwide.
12:21 Update Issues isolated to claude.ai login/logout paths; API believed intact.
13:22 Identified Root cause identified; infrastructure fix deployment commenced.
13:37 Update Incident scope widened; disruption of critical API methods confirmed.
15:25 Monitoring Comprehensive fix implemented; network traffic and service health monitored.
Concurrent technical faults affected Anthropic's model routing infrastructure. At 14:35 UTC, errors in the Claude Opus 4.6 model were isolated and patched by 14:42 UTC.
The outage highlights vulnerabilities in cloud-based LLM authentication pathways and the importance of stable API endpoints.
During the outage, automated scripts querying affected endpoints likely faced timeout responses or HTTP 500 errors, impacting prompt engineering, data parsing, and vulnerability scanning workflows.
As of 15:25 UTC, Anthropic's incident response team implemented a comprehensive fix. Systems are monitored to ensure full service restoration and prevent secondary regressions.
Cybersecurity professionals and developers should review API integration architecture, implement resilient error-handling logic, maintain localized backups, and use exponential backoff strategies to manage service disruptions.
