I think Truecrypt crashed the site. Might have just been a simple power failure, I really don't know. But, if you lost any info from the "15 hour crash", I would say blame Truecrypt. And viruses. OF COURSE.
Truecrypt is basically a file on your computer that is so secure not even the FBI can crack it after a year. You save whatever you want to this file, and it gets stored on a server you either make or choose to store the file on, and as it is being transferred to the server, TrueCrypt keeps it safe.
The problem is that it cannot be installed (at least not properly) if there is malware installed, specifically malware that tracks what someone types (or Keylogging). The reason for this is because TrueCrypt is notorious for having the most secure/stupidest password based protection since the ZuneHD: if your forget your password, you are f****d. No one but you can access it, so you better know your password.
I believe that one of the mods had the password saved just for this reason, and somehow got keylogged, hacked, and got taken down "For the lulz". The other hypothesis is that there was a trojan horse or other heavy virus that slowed down the server to a halt, and the reason it took 15 hours was because no one could remember the damn password!
Again, this probably isn't it; I don't know the basic physical tech used to keep the site running, only that it runs off phpBB. Please do not assume I am right unless someone in charge says "Yep, he nailed it". In which case, clap for me. Slowly, then get faster and faster, like in "Cool Runnings".

*The ZuneHD Comment: I have owned this awesome thing for 2 years now, and the only complaint I have (Other than it uses Internet Explorer as its internet browser instead of letting people choose) is that the password protection on it is, without a doubt, the worlds worst. At least with TrueCrypt, nothing gets erased if you mess up the password 3x; with ZuneHD, after 3x, if you fail to put in the right password, it will ask "If you forgot your PIN, would you like to delete everything on here?". So, basically, if a thief nabs it and doesn't know the PIN, he just fails 3x and the message asks "Want to make this REAAAALLY easy?!". He clicks yes, and in 2 minutes he has a completely empty ZuneHD. Yeah, great planning.
