Anthropic’s AI assistant Claude experienced a brief service outage on Tuesday, affecting multiple products including the web interface, API, Claude Code, and Claude Cowork. Users first reported issues on GitHub and Hacker News around 12:20 PM ET. Anthropic issued a status update eight minutes later, confirming anomalies with the API, console, and Claude AI. The company implemented several fixes and continued monitoring, but some models still displayed errors as of the afternoon.
The outage impacted not only casual chat users but also developers relying on the API and Claude Code. One developer joked that they’d “have to code everything manually like a caveman in December 2024.” Notably, this is the third notable service disruption for Anthropic in recent months, following an earlier three-hour downtime in early September due to a demand surge. The company’s status page became the primary public information source during the incident, and outlets like CNET have reached out to Anthropic for further comment.
