RSS - "similar to a DoS"

Netcraft reports that Infoworld.com is experiencing a flood of RSS requests at the top of every hour.

"If I didn’t know how RSS worked, I would think we were being slammed by a bunch of zombies sitting on compromised home PCs," Dickerson(of Infoworld) writes. "Our hourly RSS surge has all the characteristics of a distributed DoS attack, and although the requests are legitimate and small, the sheer number of requests in that short time period creates some aggravating scaling issues."
