We are currently transitioning from our old site to one which isn't quite finished yet. We'll be working on the site, skynet, new oCTF challenges, and a bunch of other stuff. I've put up some old challenges on aCTF3.dc949.org to keep you entertained (don't let ICMP fool you, it's up). Have fun.
[Edit]I fixed the permissions on the crypto challenges and verified that things like almostFTPd could, in fact, be exploited. If you're using PuTTY, be like Busta and make sure everything you make is raw.[/Edit]
