Also keep in mind the trends that the "consumers" of the service use;
If ohare got nuked, you would also see a serious DROP off in
passengers; much as the airlines are seeing right now.  If PAIX fell
into the ocean, presumably there would be other things going with it,
and there would be an INCREASED usage on the net as people try to
scour for information..

Not that that's particularly related to the issue, just another
example of why it's a poor analogy..

My $0.02


(BTW, I'm flying thru ohare tomorrow, so if anybody has
aforementioned intentions, please re-schedule.)

The national air traffic system makes a poor analogy to the Internet
in this case, IMHO. If O'Hare got nuked tomorrow, we'd have some
serious disruption in passenger traffic. If PAIX fell into the ocean,
OTOH, traffic would simply route around it. Isn't that how we try to
engineer the Internet?

So in other words, yes, everything is important, and yes, nothing is
particularly important.
