scheduled change of key-signing key (KSK) for DNS root (only the second time ever)

Notice

Sun 10/11/2026 12:00 AM - Sun 10/11/2026 11:55 PM

The key-signing key for the DNS root zone is being changed for only the second time ever. This does not involve any changes to our DNS servers and, according to [0], should have no impact on the functionality of our DNS servers [1].

Is your resolver ready for the 2026 root key rollover? [0]
--> KSK-2024 is trusted. Your resolver path indicates that it trusts the new root key (38696) ahead of the scheduled October 11, 2026 signing change.

For further information, see, for example, [2] or [3].
