Not everyone has the same knowledge and skills. Not everything is documented. Not everything in the documentation is current and correct. (especially after recent changes) It's not even that they won't stay up, but depending on who left the company, the oncall response may look radically different and have different time to resolution.

Yeah, but I think a judgment is being made that having the service be less reliable is tolerable.

With that amount of staff change, I’m not sure that service would inevitably come back up at all, in case of a serious enough problem.
