Well, I have run the gamut of tests on this case and I am getting pretty
stuck. Installed a demo copy of QDNS on a new machine on my same colo
network and am still having no luck getting lookups to resolve on the first
try in Safari.

I am about to buy another copy of QDNS just to get the 30 days support on
this issue, about to take this to the bind mailing list as well, hopefully
they are nice to me :-)

So far I have installed QDNS on a new machine, the problem persists, the
problem also happens inside my colo network viewing over TB2. I don't seem
to have any problems resolving local domains for which I am serving DNS on
my colo network. I think I am working locally just fine, I think that
getting out seems to be my problem.

I only just learned about the +trace option for dig, and I sure hope this is
promising, here is what I get when I look up a domain while ssh'd into a
machine on the same subnet as my DNS machine: (several attempts, comments
interspersed)

crfg.org is a domain my DNS server has more than likely not seen before:

dig crfg.org +trace

So there were 1 errors in that first one, something about the D root.
Next try was equally bad:

dig crfg.org +trace

Now I find that I can not get to the fastdns.net server in the above, the
below one seems to work:

dig crfg.org +trace

Can someone help me translate what this means and possibly offer some
insight as to why it may be happening.
