[^1]\n\nOn September 3, 2026, ChatGPT, Claude, and Grok experienced a global service outage affecting millions of users. [^2]\n\nMajor AI platforms ChatGPT, Claude, Grok, and Gemini experienced service failures on Thursday that prevented thousands of users from accessing their services normally. [^3]\n\nFrontier models from Anthropic, OpenAI, and xAI all experienced rare outages on Thursday morning, creating downtime for their corresponding AI chatbots. [^4]\n\nAnalysts 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]\n\nThe simultaneous nature of the outages suggests the root cause is located in common internet infrastructure rather than the individual AI models themselves. [^6]\n\nAnthropic indicated that Claude models Opus 4.8 and Opus 5 were interrupted but later recovered their usual error rates. [^7]\n\nMicrosoft Azure, which provides cloud services for the affected models, also experienced interruptions during the incident. [^8]\n\nOpenAI reported that ChatGPT and Codex experienced high error rates which were corrected by 12:00 PM Colombia time. [^9]\n\nAnthropic 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.
