Only "key facilities" protected
If the "key facilities" were unaffected thanks to a UPS but they still lost tens of millions of dollars from a ten minute outage, they have a different definition of key facilities than I do!
I can imagine some Samsung tech saying to his boss now "remember that $100k backup generator I wanted, that you said was too expensive...?" Of course, I remember the department which said "pay internally for backups of our server? Why'd we do that, it's been running fine for years - oh, what does 'TTS backout failure, unable to mount SYS' mean?"
We got one of those at work too, after a long power cut took out all the servers - only protects the core network and servers, though, all the edge switches are still unprotected and tend to need manual power-cycles after a power cut. Official answer is "they should all be on a UPS"...
