How to crash your web server/data center:
1) Come out with an update to an existing application that is used by millions of people on multiple platforms and that they use to access your website. Ensure this update is substantial in size. (iTunes 7.7)
2) Launch a new part of that existing website that encourages frequent reloads and increased traffic. (App Store)
3) Conduct a worldwide product launch that requires access to that website to activate the product. (iPhone 3G)
3) Have everyone who bought the first version of your product download the new OS software from the same website. (iPhone 2.0)
4) For good measure, completely upgrade a historically low-revenue/low-margin product that users use for online storage. When existing/trial/new users begin uploading 20 Gigs each, have your crisis team route all traffic through your main domain. (.Mac-->Mobileme, auth.apple.com)
5) Schedule all of this on the same day. (Brilliant)
{Yes, AppStore/iTunes was available earlier, but you get the point}
6) Be a company devoid of anyone with the guts to tell their effete, autocratic CEO that this is a bad freakin' idea, regardless of his penchant for simultaneous dog and pony shows. (Can you say Fonzie on waterskis?)
7) Reap the rewards of looking like a small company completely unprepared to be the big company they are becoming.
