Blah @ too many edits.
Oh hay, remember that story that I was telling you about, about the herd of baby taurens that were going to run from Mulgore to Stormwind, and how they crashed AD in the process?

I totally forgot about this part. This is important. Perhaps more important than anything else. (And amusing, too.)

They didn't just crash Argent Dawn. All of the people who tried to log back in to the game? They crashed the WoW Authentication Server, too. With that, people couldn't log back in to WoW on ANY realm for another 15 minutes after the event started and AD crashed. And of course, with the Authentication Server being taken out, the WoW website and forums were all knocked offline as well. (Whether it was because the Auth server going down pulled the WWW server offline as well, or if it was because so many people couldn't log into the game that they - logically - hit up the forums to find out what was going on, thereby crashing the webserver as well as everything else, is anybody's guess. :P)

Truly epic. Now that I'm remembering more details, it's hard to tell which was more epic -- the stampede event or the Boom execution event. :o

Here's the apology on WowInsider that soon followed the system-wide crash:

Oh yeah, and screenshots of all the baby tauren. Looks like they made it as far as Ratchet, at least:

... and I can't seem to view that video you linked. Even with NoScript and Cookie Monster disabled. Sorry. :(
