Update timeline

  1. investigating Sep 17, 2026, 08:59 PM UTC

    We are investigating reports of degraded performance for Copilot AI Model Providers

  2. monitoring Sep 17, 2026, 09:39 PM UTC

    We are experiencing degraded availability for GPT-5.6 Luna, GPT-5.6 Terra, GPT-5.6 Sol, GPT-6 Astra, GPT-5.3-Codex in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. The provider is working to mitigate the problem and we are monitoring recovery. We recommend choosing another model or selecting 'Auto' to continue using Copilot.
