Don't they have all the primary components on UPS systems? Their UPS setup
should allow at least an hour on batteries in case of generator failure. If
it's true that the backup uplink has no generator, that's a disgrace! The
contract should have required that both uplinks have a minimum of 1 hour UPS
and both have generators. Generators tests should be done weekly and UPS
systems tested monthly. This shows some very weak links in the system!
