I had a ddos in 01, took the entire cluster down for a fairly popular website.
Traffic distribution was very wide; everything was on port 80.
All the traffic would come in, smack the front page, then disappear.
Turns out marketing had purchased an ad on MSN which was a hot search engine at the time, we were supposed to be the top link for any search with "school, education, classes, tutoring". MSN accidentally made us the top link for EVERY search term. My T1 and my BGP frame connection were balls to the wall for 3 days.
OBV, this isn't marketing, but they're not a great target. No one's getting any money from it, They don't have any stiff corporate competition.
