Next time there's a project like this that's going to have a big first day spike it'd make sense to do load shedding and divert peak traffic to a server that says "sorry, we're overloaded, please come back tomorrow and don't panic because you have until the end of July to sign up and be on the first release of the list." That and fix the rDNS and price out some alternatives to Redmond Bloatware, of course.
...and ask the questions asked here (much!) more than a few hours prior to the event start/spike.
Coming here to ask what was asked was obviously a smart move by Mr. Callahan, but one and a half days prior to launch was way too late to successfully implement any of the (very good) advice given.
