The site is down for planned upgrades and breaking of things, please do not panic or freak out man.
This means that you need to wait a few moments. Give it another 15 seconds, and try try try again!
While you wait, why not:
Subscribe to the MCS RSS Feed. (yes I realize the irony of suggestion you subscribe to a site that isn't currently working, but it's the best way to be notified when everything is back up)
