I am currently aware of the disruptions that have been plaguing the site today. As a quick summary, we had some DNS issues, the files decided to not play nice with me, and now I have no idea what is wrong. Luckily, the only thing that is down at the moment is the main part of the site -- the forums, wiki, and mantis are all working as intended.
On behalf of Arcen, I would like to apologise profusely for the inconviences this poses to everyone, and I am currently working on finding a solution as soon as I can.
EDIT: I managed to fix the main part of the site, just some more DNS issues. Once again, many apologies for the issues!
