Claude is down for some users, with Anthropic confirming elevated errors across multiple AI models
The disruption is causing requests to fail with a β529 Overloadedβ 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: βAPI Error: 529 Overloaded. This is a server-side issue, usually temporary β try again in a moment.β
The outage appears to affect all services hosted by Anthropic, and refreshing the page doesn't help. For those unaware, error 529 meansΒ Claudeβs servers are unable to handle the current volume of requests
Thankfully, Anthropic is aware of the root cause and is working on a fix.
