Steve,

The AT&T experiences might be different, but at GTE-I, a SYN flood 
was the primary attack mechanism for one major web site that we host. 
Also, it is not at all clear that our network had a problem handling 
the other flooded traffic (ICMP Echo Reply and UDP traffic) that was 
sent to 3 other targets on our net, but the web hosts that were 
targets certainly did suffer from processing the traffic.

Right.  Yahoo, though, was flooded mostly by the volume.  I worry about 
high-volume TCP garbage sent to port 80, which you can't filter.

P.S.  Nice photo and quotes in Newsweek!

Thanks.
