  "account": "On September 21, thousands of users reported experiencing an outage with Anthropic's AI Claude, affecting various models including Mythos 5.1, Fable 5.1, and Opus 5. The company acknowledged the issues in a statement on their Status Page, stating that they were investigating elevated errors on requests to the affected models. As of the time of writing, Downdetector logged over 1,600 users facing issues with Claude. Many took to social media and the Downdetector comment section to express their frustration, with some jokingly attributing the outage to a lack of water, a common concern regarding the environmental impact of AI servers. Anthropic has since identified the cause of the elevated errors and is working on a fix, but it is unclear when services will resume. Users are advised to try refreshing the chat, clearing site data, switching to Incognito Mode, or changing networks as potential solutions.",
