Sorry all -- our host has taken down our main server due to a DDoS attack. We'll be down for at least a few hours. Back as soon as possible.
Sorry for the inconvenience!
Update: Service should be restored by midnight PDT.
Update 2: Limited service is now available. This is just to get us through until the proper fix (which will happen sometime before midnight PDT). Not everything will work.
Update 3: Things should be back to normal, and your nations should be where you left them. Thank you for your patience!
