X25519-only TLS connections to GHE.com drop on October 7
- Platform/SRE — Act: If your org uses GitHub Enterprise Cloud with data residency, audit any internal tooling, Terraform GitHub provider clients, or API automation that may negotiate TLS using only X25519 before October 7 — connections from those clients will break.
- CI/CD — Act: Verify that CI runners and pipeline scripts connecting to GHE.com with data residency use a TLS stack that offers multiple key-agreement algorithms, not X25519 exclusively; the hard cutoff is October 7, 2026.
