It's the deframbulator. In Kansas, for historical reasons power is sent by CA not AC, so it arrives 100% out of phase for the operation of normal electrical appliances on the grid. Each building service has a deframbulator which is like a voltage regulator, which flips the phase back to AC transparently. With some older buildings the mechanical mica deframbulators start to break down under load and leak current transients at about 768 microhertz into the ether. A new deframbulator is expensive so it is cheaper to just buy a large (2 cubic foot) iron core transformer to clean the common mode noise from the wiring. If you stick a tester on the ground you will find that the ground voltage level is either -90 or +90 volts. The reason the computers start to glitch out at 10:30 is all the people in the building start their washing loads at that time and turn on the hockey game. The combined effect of all those cheap korean colour TV's and washing machines sends the deframbs into a fourier loop and the 768 starts leaking like crazy. You can tell if this is the case if you turn the power of on the breaker and on quickly. If the trouble goes away it's a deframb for sure. My advice. Steal all the colour TV's in the building and start a rumour that there is a second story gang in town, selling to the pawn shops. Sell a few of them in bars for effect thru a third party. search the building for kids playing with tesla coils. Steal all CB radio freaks equipment that have linears on them. Install a large iron core transformer for plugging in all electricimicals. You could even put a line cleaner that will make up big power losses. Install a decent 20KW air conditioner in the server room to get temperature down to 65 degrees. A cranky, sweaty maintenance person is bad, bad, bad. Install a master Linux server for the basic uber-monitor server to the sub-servers. Linux is a fast no never mind router/page server, which will, in a 400 Mhz computer, outperform any cisco router ever made. I had a computer that would make disk write errors every time the elevator in the building would run.
