I have just happened to notice that since I added few “custom DNS records” few months back, they have not update and still pointing to old IP/CNAMEs but I got the usual “updated DNS: 3rddomain.tld” msg. come up.
I have just now set few more, got the “updated DNS: 3rddomain.tld” msg. but they do not work after few hours since I done it as well.
And it is this domain I have problem updating the DNSSEC as well, so I wonder if this is related to my earlier post “The nameservers set on this domain are incorrect”
