But, on Saturday morning, just minutes after the UPS went down, power was resumed in what one source described as “uncontrolled fashion.” “It should have been gradual,” the source went on."
Sounds awfully like maintainer error to me with the poor guy operating all the wrong switches when he/she realized he/she had turned off the wrong switch or the UPS failed. Not uncommon.
Does not explain why Comet House did not take over anyway. What happens if something catastrophic like a fire or flood happens to Boadicea House as they seem to be saying Comet House only takes over some of it under some controlled circumstances? That is not a proper backup.
