DNS Cluster configuration...

Hello, I've the following DNS Cluster setup in our system but I'm confused about what'll happen when for example NS1 is down and this time period I modify some DNS records from one cPanel server (which is quite possible because NS2 is online). Will it be synchronising back from NS2 --> to --> NS1 after NS1 returns to online? Here's the schematic: 3 FULL cPanel servers: - SRV01 - NS1 (sync. cahnges) - NS2 (sync. cahnges) - SRV02 - NS1 (sync. cahnges) - NS2 (sync. cahnges) - SRV03 - NS1 (sync. cahnges) - NS2 (sync. cahnges) 2 DNS-Only cPanel servers: - NS1 - SRV01 (standalone) - SRV02 (standalone) - SRV03 (standalone) - NS2 - SRV01 (standalone) - SRV02 (standalone) - SRV03 (standalone) Thank You for any advise! Regards

  Hello :) The synchronization occurs from the cPanel servers to the DNS-Only servers, based on the configuration you provided. This is standard behavior. You can manually synchronize the zones from the cPanel server to the DNS-Only servers again when the name server that's down begins to function again: "WHM Home " DNS Functions " Synchronize DNS Records" Thank you.
