Mafiaboy hosed down a few big sites - I think he had something like 850
zombies under his control.  Today's botnets are averaging some 100x the size.

The problem is cost - the vast majority of sites on the Internet really *can't*
afford the resources needed to withstand the impact of a 100K zombie botnet
or a mention on Slashdot.  Even sites with big pipes have to make judgment
calls - our site has enough OC-12's worth of pipe to ride out a small attack.
But at some point, we need to draw the line and say "We're not putting in
another OC-48 until our normal traffic justifies it, and we'll just have to
bet that we don't piss off anybody with an OC-48's worth of zombies".

10 years ago, the script-kiddies were armed with the equivalent of switchblade
knives - now they're packing the equivalent of AK-47s and several magazines
of extra ammo.
