Sark.cc.gatech.edu, the primary MX server for cc.gatech.edu, has reached the end of its usable life and will be permanently powered off on Tuesday, April 14, 2009, at 5:00 PM. The server's functions have been replaced by ace.cc.gatech.edu and ace2.cc.gatech.edu. Most users will not be affected by this maintenance. If users have any applications hard-coded to use sark's IP address (130.207.7.23), they should update those applications to point to 130.207.7.7 or 130.207.7.98 instead.
