They only seem to have two auth nameservers for faa, both within the
faa.gov domain. Don't seem to be anycasted and the 2 v4 and 2 v6 blocks
the servers are in all die just within each block run by the FAA.

Seems like an internal routing meltdown making the only 2 nameservers
unreachbable reliably.
