No one is lying. There is a "switch" from main power to backup. If there is a switch to backup and the backup isn't working then you will lose power. When you switch back to main then power is restored.

I've worked with enough UPS (Uninterruptible Power Supply) systems in large data centers to know what can happen when main power is transferred to backup and backup fails. It gets really dark and really quiet. It can also trip and even blow breakers and circuits that need to be reset or replaced when the system is set back to main power.

They probably had to fix and reset certain circuits which could result in multiple, temporary, power losses to certain systems.

Take care,
Mike
