DNS Root Key-Signing Key (KSK) Rollover Scheduled for October 11

The DNS root is scheduled to change its key-signing key (KSK) on October 11, 2026, for only the second time ever. This KSK rollover is crucial for DNSSEC's chain of trust, allowing DNS resolvers to authenticate answers using cryptographic signatures. Validating resolvers must trust the new key (KSK-2024) before the switch to prevent healthy websites from becoming unreachable.
