    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.
