Problem with ed.gov

[Baird, Josh]

Hi,

My resolvers seem to be having problems resolving ed.gov hosts.  Others
have reported similar problems, but I am having trouble figuring out
where the problem lies.  Some other resolvers seem to be resolving
ed.gov correctly.  I am able to query their authoritative servers
directly from the same network where my resolvers are located.  But, my
resolvers are not able to recurse to them.

$ dig +tcp fafsa.ed.gov

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-16.P1.el5 <<>> +tcp fafsa.ed.gov
;; global options:  printcmd

$ dig +notcp fafsa.ed.gov

Is anyone else having problems?  Can you spot anything that could be
preventing my/our resolvers to successfully query this?

Thanks,

Josh
