Why Does a Domain’s DNSSEC Validation Fail After a Nameserver Change?

Changing nameservers without coordinating DNSSEC records can leave the parent delegation pointing to a key that the new DNS provider does not use. Resolvers may then reject the domain.

What to check

Check DS records at the registrar or parent zone, DNSKEY records at the authoritative provider, rollover state, and resolver validation results.

Recommended next step

Coordinate DNSSEC key and delegation changes using the provider’s procedure and verify from validating resolvers. Informatix Systems can help diagnose domain DNS issues.
