Has anyone got experience “un-delegating” a subdomain?
We have our www subdomain delegated to another CF account (the other account is an enterprise CMS vendor). There are 2 NS records set up in our CF account for www with 2 CF nameservers (not the same ones used by our account).
We no longer want www delegated. I want to remove the NS records and add a CNAME record to another hosting service. This is exactly what I’ve done - I removed the NS records and added a CNAME, but 24 hrs later nothing has changed - the name servers have remained the same and traffic is still proxied to the CMS as set up in the vendor’s CF account.
My question is how can I get my subdomain back? I can ask the vendor to delete the subdomain from their systems (which will remove it from the CF account but also delete the website), but when I do this is it going to cause a huge multi-hour outage while waiting for the NS records to change? From what I read online I think it doesn’t matter which CF name servers are being used, but I can’t take that risk.
Thanks in advance!
