Anthropic Restores Claude API After Widespread Outage as Some Logins Still Fail

The disruption underscores renewed reliability concerns following earlier outages this week.

Claude appeared to be experiencing problems on Wednesday afternoon.

Overview

  • Claude services saw intermittent failures across the API, web chat, Claude Code, and the mobile app, with many users hitting 500 errors and access issues.
  • Downdetector recorded a surge of user reports during the incident, with tallies described in coverage ranging from about 8,000 to more than 15,000.
  • Anthropic said it identified the issue and rolled out a fix, and reported the Claude API fully recovered at 8:01 PT/16:01 UTC.
  • Some users still faced login failures, especially in Claude Code, though people already signed in were able to keep working.
  • The repeat disruption earlier in the week has pushed teams to question Claude’s reliability and consider backup tools to avoid workflow breaks.
