DNS Propagation on DNSOnly name servers
I'm having an issue on our 2 name servers with WHM DNSOnly installed. There is a DNS cluster on our main WHM to ns1 ans ns2. As far as I can tell, this replication is working but each other the name servers are not propagating normally, and when you attempt to resolve the A record for ns1 or ns2 it does not come back with a answer.
The world wide propagation shows it propagating half way around the world, - Removed - and - Removed - Our domain hosting and confirmed their are no issues, I am at a loss to explain why this is happening. Can anyone

perhaps you DNS resolvers are broken or just have not updated yet try with another resolver dig @8.8.8.8 ns1.example.com & double check that you have A records synced across all servers 0 -

Thanks, the DNS resolvers are set to the Google public IP's (8.8.8.8 and 8.8.4.4) We only have the one full WHM server which definitely has A records. dig @8.8.8.8 ns1.example.com ; <<>> DiG 9.9.4-RedHat-9.9.4-73.el7_6 <<>> @8.8.8.8 ns1.example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 9819 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;ns1.example.com.

try syncing all record to all servers and use a different public resolver to check Googles usually update with 30 min or less double Check your cluster settings to make sure they are are syncing your ns1 & ns2 which I assume are your DNS only servers check a good domain to see if it resolves dig @8.8.8.8 google.com 0 -
Hello @TOCS, Can you confirm how you have configured the role of each DNSOnly server in WHM >> DNS Cluster on the hosting server? Thank you. 0 -

Our DNS cluster is set to use ns1 and ns2 (you are correct, they are our name servers) and Synchronize Changes. Both nodes have a green status tick on the WHM > DNS Cluser page and we are not receiving alerts of a failed cluster node. Also after checking IntoDNS, it seems that some of our domains (not all) are unable to resolve the name servers (mainly seems to be .com address) ns1.example.com [] (NO GLUE) [TTL=172800] ns2.example.com [] (NO GLUE) [TTL=172800] The following was run from our main hosting server. ; <<>> DiG 9.9.4-RedHat-9.9.4-73.el7_6 <<>> @8.8.8.8 google.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 23531 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;google.com.
