I setup two DNS servers on my network: &&

I can ping the DNS servers and get a fairly good response time, when I dig them I also get a fairly reasonable response, but any website I filter through them is painfully slow (an upwards of 20+ seconds) -- verifiable by performing a tracert or attempting to access the URL in a browser.

The DNS servers are running CentOS 6.3 and BIND9 with 500MB of memory (I figure that should be more than enough?). I have a reverse look-up zone (1.168.192) along with two website zones ( and

If I access the websites using their IP the page loads nearly instantly so I do not believe the issue is with the hosting server, but that is running Ubuntu Server 12.04 and Apache2 with 12GB memory.

Any thoughts? I do not have the named.conf file in front of me but I can edit this post to include it if you feel it would be useful.

Thanks for any advice!

IntoDNS has lots of good information:


In addition, is not a CNAME and has two A records, one of which times out on port 80. The same is true for and respectively.
