DNSSEC algorithms or digest types that are outdated and no longer supported by the registration system are still registered on some domain names in our database.
An overview of which domain names this applies to is now available in a new status list on the registrar web under Domain Portfolio and DNS errors and warnings.
Registrars who have domain names with such errors in their domain portfolio must correct the registrations and ensure that only valid DNSSEC algorithms and digest types are in use.
To correct the errors, you as a registrar must perform an EPP domain update and remove algorithms and digest types that are outdated.
