Claude AI appears to be experiencing issues, with users reporting widespread API 529 'Overloaded' errors that are disrupting coding tasks and affecting Claude Code.
According to Downdetector, outage reports began coming in around 8:30 p.m. EDT on Sunday, with users reporting problems with both Claude Code and Claude's chat service.
One user reported, 'Started 5 min ago: Claude Code Opus 4.8 getting API errors -- status 529 overloaded.'
Another added, 'Taking longer than usual. Trying again shortly (attempt 4) great its been doing this for a while.'
A third person wrote, 'Try working on the desktop app. That's working just fine. I'm running multiple projects: one in the desktop app and two in different browsers. The browser ones are down, 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 keeps failing every few days.'
So far, Claude has not issued a statement addressing the outage reports.
