Michigan - and yes, power is awful in certain parts.  Especially in subdivisions where much of the power cables are above ground and strung through trees...  So bad that I was considering a whole house generator at one point but eventually moved to an industrial park for expanding business....  I also run equally old Trippline UPSes.  They run off 220v.  Every couple years we have to replace the batteries in them and other than the batteries, they still work.<p>The UPSes pretty much keep things running for a couple hours - most of my mission critical hosting servers are are in data centers these days and for the office, our servers sit on the UPSes where at most we lose power maybe an hour every couple years in the office park.  Much more often in a residential area.<p>When that large blackout of 2003 occurred we were down for couple days.
