Superbowl success?

[Sean Donelan <sean () donelan com>]

Not necessarily a major Internet event, but it appears superbowl
releated web sites did well this year.  According to Keynote's
press release http://biz.yahoo.com/bw/000202/ca_keynote_1.html
only one superbowl advertisor web site out of 35 was inaccessible
during the superbowl.

I didn't notice any significant correlation between the network
provider and the performance of the web site.

Are folks getting better at predicting advertising generated
traffic?  Or are people just massively over-provising their
web sites, and praying?
