Bind Help - NS Lookups timeout

I don't think that you understood what I was asking.
My DNS servers are resolving my own domains (ie. ionosphere.net) just fine. That's not the problem. The problem is that I am not able to use my DNS servers to resolve domains that I don't host. Using the hints in named.root.
Try doing an nslookup (or dig) --using-- ns1.ionosphere.net as your name server, and lookup the A records for covad.net, then try to do the same thing looking up the A records for yahoo.com.
One will work, and one won't. This is just one example. We have several domains that -do- work, and several domains that -do not-. This is, of course, causing a lot of problems. Mostly with our email servers which use our own DNS servers for domain lookups.
What I am trying to figure out is.. why do the internic root servers (in named.root) work for some domains, and not others?? What am I missing?
Thanks!

Works fine from here:

BTW: Stop using nslookup, use dig instead.
