Moving a domain killed my DNS!

    Hey Forum,

    Today I had to move across a website from Server A to Server B, for example's sake, lets call it x.com (No affiliation with PayPal I swear :D )

    Server A had the hostname - host.x.com
    Also Server A had the nameSpaces set to ns1.x.com and ns2.x.com

    So after I transferred the /home files to Server B, I went ahead and updated x.com's registrar's DNS.
    Which is fine, x.com now resolves to Server B's IP.

    However, now it seems that ALL domains on Server A are no longer resolvable by DNS.
    For example, one of the domains on Server A is Y.com

    Whenever I try:
    Code:
    traceroute y.com
    ping y.com
    
    I receive 'host unreachable' or a timeout

    Whenever I execute:
    Code:
    nslookup y.com
    // Returns 
    // ;; Got SERVFAIL reply from 8.8.8.8, trying next server
    // ;; connection timed out; no servers could be reached
    And dig y.com

    Returns
    Code:
    ;; QUESTION SECTION:
    ;y.com.		IN	A
    I have changed Server A's NameSpace to ns1.y.com and ns2.y.com
    And have also changed the Servers hostname to host.y.com

    I am still getting this problem! What can I do?

    Oh and Yes, I can ping the Server Directly using it's IP.
    I can also access cPanel/FTP/SSH perfectly, just nothing that needs the DNS!

    Named is running fine too:
    Code:
    service named status
    number of zones: 18
    debug level: 0
    xfers running: 0
    xfers deferred: 0
    soa queries in progress: 0
    query logging is OFF
    recursive clients: 0/1000
    tcp clients: 0/100
    server is up and running
    What could be wrong? I'm pulling my hair out over this mystery!

    Thanks in advance

    Hello :)

    If the IP addresses have not changed, the other domain names should not have stopped resolving. Have you updated the name servers for the domain name at it's domain registrar?

    It's difficult to know the exact reason without the specific domain name that's failing to respond to DNS requests. Could you open a support ticket so we can take a closer look? You can open a ticket using the following URL:

    If you post the ticket number here, we can track the progress for you.

    Thank you.
