Anthropic's AI chatbot Claude experienced a widespread outage on Wednesday, leaving many users unable to access the service as reports of disruptions surged across social media. According to Downdetector, complaints spiked sharply, and the disruption appeared to impact multiple versions of Anthropic's latest Claude models. In an update posted on its status page, Anthropic said it had identified the cause of the elevated error rates and was working to restore normal service. "We have identified the cause of elevated errors on requests to Claude Mythos 5, Claude Fable 5, Claude Opus 5, Claude Sonnet 5 and are working on a fix. We will provide an update as soon as possible," the company said. Anthropic added that its engineering teams were continuing to work on resolving the issue, though it did not provide a timeline for when services would be fully restored. As the outage continued, users reported being unable to generate responses from Claude, with many encountering loading errors after submitting prompts. When users attempted to interact with the chatbot, Claude reportedly displayed the error message: "This response didn't load." Anthropic has not disclosed the specific technical cause behind the elevated error rates or whether the outage was linked to any underlying infrastructure issues. The outage quickly became a trending topic on X, where users shared their frustration over the service disruption. The company has yet to share further details on the root cause of the outage or when all Claude services will be fully restored.
