Generator ATS Provides Power During Partial Power Loss

How a Generator Automatic Transfer Switch Works and is a Very Important Part of the Home Generator System

A Generator HTS/ATS Can Provide Power When One Leg Of Power Is Lost
Question: I am in a building in Summit county where there are no known power outages. I am assuming there is three phase coming in to our building by the looks of the transformer outside. We have a backup generator which is a Generac Elite series that is supposed to supply backup power for half of the building. Earlier today the power went out in 1/3 of the building.

I am assuming just one phase went out, and so the generator kicked on and has been supplying power ever since. Now the reason I am thinking just one phase went out is because we have two HTS transfer switches. One has standby operation lit with utility power not lit, and the other has utility power lit and the switch position is utility. Is it possible that there is a problem with the power company that just one of the phases are down? And if so, should I report this as a power outrage?
