United.com having DNS issues?

["Christopher L. Morrow" <christopher.morrow () mci com>]

Not horribly on topic, but perhaps there is a united.com person listening:

www.united.com's NS servers are -
  dns01.uls-prod.com.
  dns02.uls-prod.com.

DNS01 seems 'fine' (responds atleast)
DNS02 seems to return 'servefail' for everything...

Servefail seems to make cache dns servers not attempt lookups from the
other NS's on record. This seems 'bad', if your dns server is busted could
you just null route it or turn it off?

Actually, now as I test both NS's are toasted :( Hope the record's TTL is
long enough for you.
