    Exclamation DNS Issue, not resolving

    Hi,

    Suddenly, without warning OpenDNS's 208.67.222.222 stopped resolving correctly an A record of one of our domain. But 208.67.220.220 works without any problem.

    This just happened 5 minutes ago while working on this particular subdomain where I got DNS-not-resolving issues.

    Nothing was changed to the DNS since I do not have access to it.

    What could be wrong?

    Greetings:

    Have you contacted OpenDNS to find out?

    Thank you.

    3600 ; refresh (1 hour)
    900 ; retry (15 minutes)
    604800 ; expire (1 week)
    43200 ; minimum (12 hours)
    )
    NS dns1.myhost.net.

    Both work without problem giving me the proper information. Tried using @server_IP for both name server also.

    This is kind of a bump of thread I started a few days ago (http://www.webhostingtalk.com/showthread.php?t=898945)

    During lunch time, OpenDNS stopped resolving my subdomain.

    Code:
    nslookup - 208.67.222.222
    > client.domain.com
    Did not resolve.

    But since 15 days,
    Code:
    nslookup - 207.164.234.129
    client.mydomain.com
    Never worked. 207.164.234.129 is my ISP DNS. Tried with a different ISP and it does not work either

    It is recommended that you directly query the authoritative name server IP address for the Fully Qualified Domain name and determine if the DNS record resolves. If it does, then it's a problem of the local resolver you're using else try reloading the DNS zone file in that respective name server after incrementing the serial and check /var/log/messages.
