Could well be that guy in the next dorm, who has an anonymous FTP service running for his 39 Gigabyte MP3 collection. Or the IT department looking at live video feeds from De Wallen in Amsterdam. Or it could be that eveyone unsuspectedly installed a trojan for DDoS purposes on their PCs.

Either way, if your IT admins can't figure out how to block that traffic, I'd hate to take the Computer Science course at your college/university.

Finally "I thought I might help our IT dept by doing a little research" and "I can't even download Morpheus to play with it!" is contradicting
