Deja Vu all over again.
There is a wider problem here isn't there.
I've coloed and rented from a lot of data centers and hosting companies over the years, and without exception all of them have had an "unplanned" outage for an extended period at some point or another. Without exception all of them have also boasted a robust and redundant UPS system and hot fueled diesel generators. Of those whose outage was a power issue where the UPS and generators where supposed to ensure an uninterrupted power supply, without exception they all failed.
In one instance it was a issue with power blowing out the UPS circuit hence cutting UPS power and disabling the path of power from the generators. In another it was the transformer room having it's floor and walls blown in which severed the physical connection to the generators. A mobile genie was trailered in that was wired into a hastily reconstructed power panel and was then found not to be man enough for the job.
It seems that whenever a scenario occurs that UPS and generators are called for, other factors impede and these intangibles are never envisaged. There is a mind set here that says, "We've got UPS and generators, so power redundancy is sorted."
Well it's not is it, and there seems to be a whole area here of power systems design that is in need of far greater scrutiny.
