NetCraft has an amusing news item this week talking about how RSS aggregators cause traffic on sites to essentially pulse:
Infoworld.com experiences a "massive surge of RSS newsreader activity at the top of every hour," according to Chad Dickerson, the CTO of Infoworld. "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 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."
Wonder if it's worth 'randomizing' the update time on the feeds I subscribe to -- or even better, if the aggregators themselves had an option to “Download every 60 minutes +/- 20”.
