Google webmaster tools tells me that I have DNS lookup timeout errors. My nameservers and bind are configured properly and reports no errors.

Question: Can I simply change the nameservers in /etc/resolv.conf to use the resolvers from OpenDNS or could this break my server?

Could it be a firewall issue? I am using CSF firewall at the moment.

When asking questions that require troubleshooting DNS it is incredibly helpful to know the domain name in question. – voretaq7 Sep 7 '11 at 15:52

If Google's telling you that you're having timeouts, it's not your server's DNS config, it's the authoritative DNS servers for you domain.

Check that all the servers in your domain's registration record are still valid and hosting working copies of your domain's zone.

How exactly would I check the domain records? A simple query lists my nameservers, but not more. How can you be so sure that my hosting provider did not misconfigure their resolvers causing a DNS timeout when the domain gets translated. – mashup Sep 7 '11 at 15:42
When I do a nslookup I also get an authoratative answer – mashup Sep 7 '11 at 15:49
