OpenAI, Anthropic and Grok report service disruptions

Several artificial intelligence companies were hit by service disruptions at the same time, based on user reports on Downdetector and statements posted on company status pages. OpenAI said ChatGPT and Codex were experiencing issues. Anthropic said it was investigating errors affecting Claude and was working on a fix. SpaceXAI said Grok was down and that it was investigating the outage. Downdetector figures cited in the report show the scale of user complaints differed across the affected services. OpenAI had more than 12,000 problem reports, while Claude had about 1,200 reports and Grok had roughly 1,000. The update did not provide a cause for the disruptions or a timeline for full recovery. The information was attributed to Downdetector user reports and the companies’ own status pages, indicating that the outage signals came from both user-side reporting and official service monitoring channels.
