I doubt any amount of staffing could address lack of specialism in dealing with power or air conditioning issues, both likely involve infrequent maintenance by external vendors. 20 people blowing up the phone to a vendor doesn't fix a problem any faster than 1 etc.

Amazon goes to the extreme of putting its own custom firmware on switchgear because the choices that vendor makes in theirs doesn’t align with their objectives.

I don’t think AWS is blowing up a vendors phone when something goes wrong in one of their facilities.

Amazon doesn't make their own AC units or generators, so it's still likely they would need external support for a case like this.

That's some magical thinking, thinking that you don't need hardware people because you wrote some software.

All the same gear is still there, its control functions are just ceded to Amazon panels. And integrated to the point of even removing some PLC like devices.
