Claude AI appears to be experiencing problems, with users reporting widespread API 529 “overload” errors that disrupt coding tasks and impact Claude Code.
According to DownDetector, outage reports began to arrive around 8:30 pm EST on Sunday, with users reporting problems with both Claude Code and Claude’s chat service. As of 8:45 p.m., DownDetector had received more than 4,000 reports of outages.
One user reported, “Start 5 minutes ago: Claude Code Opus 4.8 has an API error – status 529 Overloaded.”
Another added, “Took longer than usual. Tried again later (attempt 4), great, it’s been doing this for a while.”
A third wrote: “Trying to work on the desktop app. Works great. I’m running multiple projects: one in the desktop app and two in different browsers. The browser project is closed, but the desktop app is working for me so far.”
Another frustrated user complained: “I should have used OpenAI to pre-plan this prompt. Claude fails every few days.”
So far, Crowder has not issued a statement in response to the outage reports.
