Tim,
What was the reason for shutting it down?
This reminds me of a story from years ago where a young friend contacted me before a trip to the University of New Hampshire for a Linux LUG meeting.
He asked me if I would go to a particular dorm and knock on the door of what had been his door room. I was to ask if I could unplug the box that was in the corner of the closet in the room. The system had been running for five years in his former dorm room and he had forgotten the login password. He did not want the machine back, just wanted it unplugged.
A young woman answered the door, heard my explanation and let me unplug the machine. "We were afraid to unplug it" she said.
Your machine beat his machine on uptime.
