Source 2013 MP Security Breach / TF2C Offline

Per the recent security issue discovered in Source2013 MP (http://tf2classic.com/forums/discussion/100)

we've decided to take our TF2C servers offline for the security of all. We'll bring them back up as soon as the exploit has been fixed or blocked.

Update: Valve has patched the exploit and the servers are back up.
