There are no new ideas in the message, I just don't know if the existing components have been previously combined in the way I'm proposing. If they have been I couldn't find anyone talking about it. Anyway...
Most websites live forever in obscurity getting a few hundred hits a day at best. However, if that same website gets linked to from a popular super-recommender like slashdot.org or boing-boing.net the hits can jump from 100s per days to 100s per minute. This phenomenon is called the slashdot effect (http://en.wikipedia.org/wiki/Slashdot_effect). On a server built with a low hit volume in mind it's pretty devastating, generally resulting in complete denial of service.
