For those wish to know.. The University of Hawaii (UH) has had a
long-standing relationship with NASA, providing the University with
Secondary DNS since Hawaii's connectivity to the net. That arrangement
is not new. The physical dispersion of UH campuses and community colleges
-- has over the years complicated network topology (I am in no way
responsible for it, NOR do I answer to complications within it...:) ).
Correspondingly, DNS as a function, does experience difficulty
with respect to stability -- within the UH system.
I am not going to go there... when it comes to HI.US

I did not want to be that complete Sean.. :) yes, however, if the bits
are experiencing a problem crossing a bridge -- no matter where the bridge
is (on land.. over a stream and between islands), what you ultimately end
up with is 'byte-jam' or as they say here in Hawaii, 'byte-jam-up'.
It does not ease the situation WHEN your bits transit one provider's
backbone (whom you chose to assure redundancy) does ultimately receive
transit (at times such transit is not for long distances..) from a yet
another whose infrastructure is now effected. I am not suggesting however,
that is the case here.. AT&T is investigating. :)
I am going to jump out of this conversation all, and get back to work.
Thought that it would be interesting to report this to all who were
