Then I got a UPS. System stays up for months at a time, and then comes down usually because of some pilot error or the power going away for longer than the UPS stays up. I've been running 3.51m since about a week after it was available, and I've not noticed any problems with the machine up 24 hours a day. However, the machine is mostly a personal convenience, and it is lightly used (i.e., not running netnews, no other regular users, low uucp traffic, etc.) I'll have to pay more attention to window switching time, though. My personal theory is that the 3b1's power supply is sensitive to the power coming from the line. The $500 I spent on a UPS is one of the best investments I've ever made. -wilkes
