resolving problems when some authoritative servers are down

[John]

Problem resolved, or at least determined.

The NAVCIRT (Navy Information Assurance) was publishing a document telling
the military to block an entire class B address space from which we have a
/19 assigned to us.

Thus, DNS is not very workable when you are firewalled off from the the DNS
servers you are trying to reach :)
