Claude is down for some users, with Anthropic confirming elevated errors across multiple AI models
The disruption is causing requests to fail with a “529 Overloaded” message, including in Claude and tools that rely on its API.
Anthropic began investigating the outage at 7:49 p.m. UTC on July 29. At 8:33 p.m. UTC, the company said it had identified the issue and was working to resolve it, but did not reveal the underlying cause or provide a recovery timeline.
During the outage, I repeatedly encountered the following message: “API Error: 529 Overloaded. This is a server-side issue, usually temporary — try again in a moment.”
