    Exclamation Need DNS troubleshooting help


    We have one domain that our server cannot connect to

    ; <<>> DiG 9.3.4-P1 <<>> boe.ca.gov
    ;; global options: printcmd
    ;; connection timed out; no servers could be reached

    I can query some other servers and retrieve the information such as
    $ dig @8.8.8.8 boe.ca.gov

    ; <<>> DiG 9.3.4-P1 <<>> @8.8.8.8 boe.ca.gov
    ; (1 server found)
    ;; global options: printcmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 59290
    ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

    ;; QUESTION SECTION:
    ;boe.ca.gov. IN A

    ;; ANSWER SECTION:
    boe.ca.gov. 3774 IN A 134.186.249.87

    ;; Query time: 47 msec
    ;; SERVER: 8.8.8.8#53(8.8.8.8)
    ;; WHEN: Tue Dec 18 09:18:04 2012
    ;; MSG SIZE rcvd: 44

    I can query ca.gov successfully from our servers.

    Looking at this a little more the Authoritative servers for boe.ca.gov are

    ns5.net.ca.gov
    ns6.net.ca.gov
    ns7.net.ca.gov

    I can query ns6 with dig but not ns5 or ns7. All I get is “connection timed out; no servers could be reached”. I assume this could be my problem with resolving boe.ca.gov.

    None of these servers respond to pings including ns6 and all traceroutes end in time outs(even ns6 that I can query).

    Some suggestions please!
