Anthropic’s Claude outage disrupts chat, Code, and API for hours

Anthropic’s Claude suffered a widespread outage on August 5 that disrupted the chat service, Claude Code, and the API for several hours, with users seeing elevated errors and “unexpected capacity constraints” messages. The company said it identified the issue, deployed a fix, and monitored recovery as affected models including Claude Mythos 5, Fable 5, Opus 5, and Sonnet 5 were hit. The outage mattered because it affected both everyday users and developers relying on Claude’s consumer and programming tools, and reports suggested the disruption lasted more than five hours before service began stabilizing.
