Summary
Anthropic said by 17:30 EDT it was seeing recovery across most Claude models, though some users were still hitting errors and latency.
529 Overloaded messages spread across Claude and third-party tools using its API after servers could not handle request volume, causing requests to fail worldwide.
7:49 p.m. UTC marked the start of Anthropic's investigation, and by 8:33 p.m. UTC the company said it had identified the issue and was working on a fix.
Anthropic has not disclosed the underlying cause or given a timeline for full recovery, leaving some API-dependent services still exposed to intermittent disruption.
