No. Tiger Woods, Rocco Mediate, and the U.S. Open were responsible for
evidence that your network was not adequately provisioned for the
unexpected demands for the "real world". No malware or miscreants
involved...just demand for bandwidth which exceeded normal parameters by
a wide margin.

My point in not to argue your choice of words (though I do), but to
point out that this sort of thing is going to be a huge problem as time
goes on. You need to have significant over-provisioning (not good
for the bottom line), block the high-bandwidth stuff (also not good for
business if people can't see Tiger), or you need to do some sort of
shaping to not piss of anyone too much while keeping expenses in line.

Good luck! (Now throw in "net neutrality" and see where we are heading.)
