wow I would hate to have that job, that is what telnet is for or a terminal, so you can send commands from your home to the server like reboot.
Thats what works the other 99/100 times. Every once in a while one gets stuck or has a hardware problem. When theres 500+ servers your odds start to go up that something is gonna hit the fan every once in a while.
Oh well.. I got 34 minutes to run to the bar and do some shots before 2am, got nothing else to do here
