   Hi all,

   Please accept our apologies for last night's web and ftp outage, 
which lasted from aproximately 8:40 p.m. EDT until just after 
midnight.  The content management system of one of our virtually 
hosted sites was compromised, driving the load up on our vhost 
servers, and a simultaneous UDP flood threw our load balancers for a 
loop.

   We're still in the process of cleaning all of this up, but our web 
and ftp services have been back up since midnight EDT and we've taken 
steps to ensure that this particular problem doesn't happen again.

   A reminder on the importance of running current versions of software 
packages, and the benefits of healthy paranoia when considering file 
and directory permissions, group access, etc.

   Thank you all for your patience through this, and an especially huge 
thanks to John Reuning, who graciously (and expertly) volunteered his 
services during last night's investigation.

   Cheers,					919.962.5646 w
