I am questioning the details of the culprit, that is  - what happened to the backup generatir, did they buy it on Alibaba?

Generators fail. Even well known name brand stuff like Caterpillar, Detroit, etc blow up now and then, especially older ones which it was mentioned this was. These are big diesel engines, they require maintenance and occasionally stuff breaks. If it spins a bearing, or has an injector problem, or something like a bad seal in a turbocharger can cause the engine to run away consuming its own lubricating oil until it throws a rod through the side of the block and spills oil and/or fuel all over the hot exhaust system and then you have a fire.

A backup generator's keword is 'backup', isn't it. Some robustness is supposed to be embedded in it from the get go starting from specs.
PaulAm:
Don't forget that part of the backup power architecture is a humongous UPS.  It's job is to keep everything up until the genset is up and stable.  Quite possible something went wrong in that gear.

My thought after the first day was that EEs everywhere across the world were showing an unexplained increase in productivity  :-DD

Assuming we have a VW Passat (which claims 1780 litres of cargo space with the rear seats down), our modern equivalent of the station-wagon-full of tapes is potentially something like 1780 x (100 x 100 x 100) x 6GB, or around 10 exabytes (10x10^9 GB).

And yes I know we wouldn't get that capacity, they're slow to write to, and so on and so on, but it does make one think.

1TB microSD still seems like sci-fi territory to me...   an amazing milestone.  Next:  10TB!  :D
