The site and forum came back up around 4:15 PM, after our host Telefragged temporarily moved us to a different server.
In the mean time, we have temporarily disable forum attachment uploads and downloads database uploads. We will re-enable uploads as soon as we are back to our original server.
Thanks for your understanding and we apologize for the inconvenience.
EDIT: I have re-enabled uploads, although we are not yet back to original server.
