## The brief

GitHub Enterprise Cloud with data residency will reject HTTPS clients that offer only X25519 key agreement from October 7, 2026. GitHub says most current clients already support P-256 and need no action. Explicitly restricted clients, proxies or security appliances need a compatible configuration; SSH connections and other GitHub hosting scopes are outside this change.
