Public — what happened

Summary

GitHub Copilot said that on August 24th, 2026, users of the Claude Fable 5 model saw more errors than usual, and some requests stopped partway through a response. According to the company, the trouble lasted from roughly 06:35 to 07:25 UTC and affected only that model, with other models working normally. GitHub Copilot attributed the problem to an outside provider it relies on and said the provider applied a fix that resolved it. The incident was marked resolved, and the company said it is working with the provider to make the service more resilient.
