Major artificial intelligence platforms experienced widespread service disruptions on Thursday morning, affecting millions of users globally. ChatGPT, Claude, Gemini, Copilot, and Grok all reported technical difficulties nearly simultaneously, marking an unusual event in the AI industry. Reports on DownDetector indicated the problems began around 11 a.m. ET, with thousands of users documenting access failures across multiple services.
Individual status pages revealed the extent of the technical issues. OpenAI reported elevated error rates across its ChatGPT and Codex systems and noted “degraded performance” as mitigation efforts were underway. Anthropic confirmed that multiple Claude model versions were impacted by the outage. While isolated outages affecting single platforms occur periodically, the simultaneous failure across competing AI providers proved exceptional and unexpected.
By early afternoon, service restoration efforts showed progress. Anthropic announced Claude had returned to full operation following an infrastructure issue that had disrupted multiple services. DownDetector metrics indicated declining error reports, and social media users confirmed improving access to previously unavailable platforms. However, OpenAI continued monitoring system recovery at that time.
The root cause of the coordinated outages remained unclear as of the latest updates. Industry observers noted the unusual nature of seeing major AI providers experience problems at the same time, though specific technical explanations were not immediately available.
