>dedicated "production support" team

That's interesting, so if some bug pops up during the weekend they will just revert back? And then that bug gets handled later. Or is there also so rigorous QA process that bugs rarely happen, and it's more like infra issues that the "product support" team can handle on their own?

The interesting part is that I think on-call is not only about infra issues etc., but could also be bugs in the application or some other weird behavior, which I'm assuming the "production support" wouldn't know how to handle. Maybe there is some huge amount of process to handle all that I'm just oblivious of, never having heard of this before?
