Sigh, as somone else already pointed out, the root-servers manually zone transfer
and will not nessesarily expire the zone.  At any rate I can see the problem lasting
long enough to impact anything.  Some people might even claim DNS is not required for
proper functioning, and that DNS isn't in the Nanog charter, although perhaps root-servers
are as they have some impact on performance.  I don't really beleive that the operational
folks at network solutions would actual do delibert things to interfere with root zone
operations.  Frankly while all the things network solutions has done lately, not one
of them seems to be with the scope of this mailing list, as no offically supported
operational functions have been broken.  (I can see how if you wrote a script that
depending on a particulaj output of whois, how it would be annoying, but I can't recall
the RFC where that particular output format is specified.  I don't believe WWW services
were ever required.

Ah well, off to do operational related things, I guess I should ignoring nanog more,
as it just doesn't seem relevant to anything in particular.  (Other than whining.)
