Yeah, I have this argument with the Bellheads all the time.  We'll
never have to worry because we all run our own SCP's.  Tell Canada
that.  Its just the difference between a static cache and a dynamic
cache.  Whether you get the information on magtape from Bellcore, or
via AXFRs from NSI, the data comes from somewhere.

ObGeek: for those that care, the master copy of the north america
1-800/888/877 database is also in Saint Louis.  For such a sleepy town,
there are a lot of interesting technological knooks and cranies.

It is important to have both.  You don't want all your name servers
sitting in the same rack (plugged into the same 6-socket electric cord),
nor do you want all your name servers sitting on the same subnet.  It
doesn't matter how many you have, if they all go away due to the same
problem.
