Speaking of the exchanges (at least the sanely operated ones), there’s a reason the stack is simplified compared to most of what is being described here. When some component fails you absolutely do not want to spend time trying to figure out the underlying cause. Almost all the cases you hear in media of exchange outages are due to unnecessary complexity added to what is already a remarkably complex distributed (in most well designed cases) state machine. You generally want things to be as simple and streamlined as possible so when something does pop (and it will) your mean time to resolution is inside of a minute.
