I’m typically fascinated by the types of questions you ask like you’re the Mystical Merlin or something.
I’ve literally been in hundreds of environments, done hundreds of deployments, worked in small-ish environments with servers numbered in dozens as well as massive environments with servers numbered in hundreds of thousands, and not once have I run in to the types of scenarios you bring up here.
Makes me think I missed something in my education, or I’m doing somnething wrong.
