The degradation affecting Copilot has been mitigated. We are monitoring to ensure stability.
Copilot is experiencing degraded performance. We are continuing to investigate.
We have applied the mitigation and are seeing signs of recovery. We will continue to monitor and expect full resolution soon.
We are experiencing degraded availability for the GPT-5.3-Codex, GPT-5.6 Luna, GPT-6.1 Sol, GPT-5.6 Terra, GPT-6 Luna, and MAI Code 1.1 Flash models in Copilot products and IDE surfaces. We have identified the root cause and working to apply a mitigation. While we work to resolve the issue we recommend choosing another model to continue using Copilot.
We are experiencing degraded availability for the GPT-5.3-Codex, GPT-5.6 Luna, GPT-6.1 Sol, GPT-5.6 Terra, GPT-6 Luna, and MAI Code 1.1 Flash models in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue we recommend choosing another model to continue using Copilot.
We are experiencing issues with upstream model providers resulting in a degraded experience across Copilot services. The team is actively investigating the issue.
We are investigating reports of impacted performance for some GitHub services.

Your coding agent knows when GitHub is down, and tells you when a failure is theirs, not yours. You can also get GitHub incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "github" and tell me if GitHub has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
