Many years ago, I had an account on a service that shall remain nameless here. Their main shell machine was maintained by a gentleman who had been a member of the BSD group at Berkeley. Due to a change in management, the shell machine become unmaintained. Today, by mistake I logged into it (used an old script, which had the wrong host name hardwired), and was amazed to see that the unmaintained machine is working just fine:
The machine is a 3.2 GHz Xeon (32-bit, obviously) with 2gig of memory. It runs with two Western Digital 1TB disk drives (WD Reds), which seem to be doing excellently. I bet the uptime is determined by power problems. Fundamentally, this machine has been running without any maintenance for over 10 years now.
