No, but you should put it in.

A random af.mil server tells me that the two name servers for rl.af.mil
are babs.rlcn.rl.af.mil and buster.rl.af.mil.  Neither responds to a
query for name servers for rl.af.mil, or even to resolve their own
names.

I would call this a more serious problem.

Pings to neither system respond, but I would not expect them to for an
af.mil system ...   ;-}
