Both the primary Claude.ai platform and the company’s specialized coding tool Claude Code were impacted. Multiple customers found themselves locked out, unable to authenticate or interact with the AI system.
While consumer-facing services struggled, Anthropic noted that its developer-focused API maintained normal operations. The core problems appeared concentrated in authentication mechanisms and the consumer web portal.
Social media platforms filled with user-submitted images displaying service unavailability notices. Customers who had been logged out found themselves unable to reconnect to Claude’s application interface.
Technical Breakdown Analysis
Anthropic acknowledged detecting abnormal error rates impacting multiple critical infrastructure components. Official status channels documented issues affecting the claude.ai website, administrative console, and development tools.
Technical monitoring systems first flagged the anomalies at approximately 11:49 a.m. London time. Engineering teams mobilized immediately upon detection.
Third-party outage tracking services registered thousands of user complaints spanning numerous geographical locations. Common issues included inability to submit queries or retrieve previous conversations.
