Is Claude Down? Anthropic Confirms Fix for AI Chatbot Outage

Anthropic confirmed at 11:28 a.m. ET on Sept. 29 that its AI tools were returning to normal after an hour-long outage that began around 10 a.m. ET and affected Claude, Claude Code, Cowork, Console and API tools, with Downdetector reporting spikes from tens of thousands of users. Anthropic applied a mitigation at 10:36 a.m. ET that dropped error rates substantially, but warned that messages sent between 10 a.m. and 10:59 a.m. ET may not have been saved and that single sign-on and Apple account logins remained broken, recommending users avoid logging out. Spotify also saw an outage-report spike about half an hour earlier, while ChatGPT and Google Gemini saw only small spikes in the hundreds of reports.

UPDATE 11:28 a.m. ET: Anthropic confirms its AI tools are returning to normal after an hour-long outage affecting its chatbot, Code, Cowork, and more. If you attempted to use Claude between 10 a.m. and 10:59 a.m. ET today, Anthropic warns your messages may not have been saved. Expect more updates from the AI brand throughout the rest of the day, as it says it will continue to monitor any continued errors in the coming hours. Original story: Struggling to access Claude AI? You're not the only one: another outage is preventing tens of thousands of users from using Anthropic's tools. The outage began around 10 a.m. ET on Sept. 29, when Downdetector https://downdetector.com/status/claude-ai/ reports began to spike. Anthropic acknowledged https://status.claude.com/ the issues 20 minutes later, saying that almost all of its tools were experiencing issues, except Claude for Government. Claude AI, Code, and Cowork are all experiencing partial outages, while Console and API tools are showing what Anthropic calls "Degraded Performance." Anthropic is working on a fix and says it applied a "mitigation" at 10:36 a.m. ET, which saw error rates drop "substantially." However, the brand acknowledged that it wouldn't be enough to fully fix its services, meaning you may be locked out for longer. In its most recent update, Claude's status website said, "Existing conversations are mostly working again." However, there's a second issue that prevents users from logging in via single sign-on or an Apple account. Anthropic recommends that you avoid logging out to maintain access. It also says that starting new text or voice conversations, making purchases, uploading files, and Claude Code or Cowork sessions are still experiencing issues. Anthropic says it's working on a fix for these problems and will provide a further update by 11:30 a.m. ET. Meanwhile, Spotify also saw a spike in outage reports today, about half an hour earlier than Claude, according to Downdetector. The streamer said it was aware of issues at 10:23 a.m. ET, and has yet to provide a further update. At PCMag, we found that the app had trouble loading songs from an album, but started working a few minutes later. Other rival AI services, ChatGPT and Google Gemini, saw a small spike in outage reports on Downdetector, but the numbers were in the 100s rather than the tens of thousands. At PCMag, we encountered trouble with Claude, but not on ChatGPT or Gemini. Early in September, a major outage https://uk.pcmag.com/ai/167069/chatgpt-claude-gemini-and-more-are-all-down-right-now caused various AI providers to struggle to keep their services live, including Anthropic's Claude tools.
