Nobody Is Saying Why OpenAI and Anthropic Had Outages Today
On Thursday morning, OpenAI, Anthropic, and xAI experienced rare outages, disrupting their AI chatbot services. xAI's parent company, SpaceX, attributed Grok's issues to a failure at its Memphis computing center. Anthropic reported "partial service disruption" affecting "Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5," which was resolved by 9:16 AM PT, with Claude Sonnet 5 also briefly impacted. Despite multiple industry-wide disruptions, OpenAI and Anthropic have not indicated a common cause, and major internet infrastructure providers have not reported related issues.
Unlike previous incidents where multiple outages pointed to a shared infrastructure issue, this event lacks a clear common cause, with major providers reporting no related problems.
