Users worldwide reported simultaneous access failures affecting popular artificial intelligence services including OpenAI, Claude, Grok, Google Gemini, and Cursor. [^1]

On September 3, 2026, ChatGPT, Claude, and Grok experienced a global service outage affecting millions of users. [^2]

Major AI platforms ChatGPT, Claude, Grok, and Gemini experienced service failures on Thursday that prevented thousands of users from accessing their services normally. [^3]

Frontier models from Anthropic, OpenAI, and xAI all experienced rare outages on Thursday morning, creating downtime for their corresponding AI chatbots. [^4]

Analysts suspect the disruptions are related to hyperscalers such as AWS and Microsoft Azure, which host the data centers and cloud infrastructure for these services. [^5]

The simultaneous nature of the outages suggests the root cause is located in common internet infrastructure rather than the individual AI models themselves. [^6]

Anthropic indicated that Claude models Opus 4.8 and Opus 5 were interrupted but later recovered their usual error rates. [^7]

Microsoft Azure, which provides cloud services for the affected models, also experienced interruptions during the incident. [^8]

OpenAI reported that ChatGPT and Codex experienced high error rates which were corrected by 12:00 PM Colombia time. [^9]

Anthropic reported errors in Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5 models, stating that affected models had been reduced and services were returning to normal operation. [^10]

Grok, developed by xAI, reported experiencing problems on its status page, with the company stating it was working to restore the service as soon as possible. [^11]

OpenAI spokesperson Kathleen Chaykowski told WIRED that a routing error starting around 7:43 am PT on Thursday, September 3, made ChatGPT and Codex unavailable for some users across platforms. [^12]
