Breaking change to GitHub Copilot service endpoints

Starting tomorrow Tuesday, September 26, 2023 we are updating the service endpoints for organizations with GitHub Copilot Chat beta enabled. If your organization uses a firewall to restrict network traffic, we recommend updating your allowlist to include *.githubcopilot.com if you haven’t done so already. This endpoint is required to deliver Copilot Chat messages.

If you are not ready to upgrade to this new endpoint, you can pin your GitHub Copilot Chat version to 0.7.1 or earlier.

If your organization doesn’t use a firewall to restrict network traffic, then no change is necessary. For a complete list of GitHub Copilot service endpoints, see our docs.
