We were running on a week old backup for a few days, but are now back to our main webserver, no data loss. Actions have been taken to prevent this from happening in the future. At the moment, any new accounts, uploads, forum posts, etc. from the last few days are not here, but I will be trying to add them, so hopefully they will re-appear soon.
FYI, if there are ever issues accessing the site, the best way to find out what is up is by IRC. This is actually much easier than most think. Just go to this URL http://p2p-network.net/webchat.php type in your username and the channel #torrentshack-help and click Start.
Stay tuned for a more in-depth report of everything soon
