The .ie ccTLD had finally removed DNS checks from its processes. Up until the change, which came last night, any new registrations, transfers or other updates would be delayed until the DNS delegation had been checked.
What that meant in reality is that if a domain’s delegated nameservers were not 100% compliant with the RFCs then the registration or change would be stalled.
While technical purists might appreciate that domain registries force this kind of compliance with RFCs, in reality the DNS checks caused more headaches for registrars and registrants than anything else.
The change should mean that .ie domain registrations (and updates) get processed a little bit faster, which is, obviously, welcome.
