I will be rebooting servers starting at about 12:15AM October 11th (about 1/2 hour from now) in order to make updates effective.  This will interrupt all non-duplicated services, services which are duplicated, external mx mail receiving servers, DNS servers, radius authentication, all will experience an interruption in one of the duplicated members.  Services which are not replicated, shell servers, web server, ftp server, will experience an outage lasting approximately ten minutes.  This is necessary in order to keep software current.
