Very few deployments experience actual failures. Could be some fridge-door/light situation going on.

I think that is meant to be parsed as: Just like you can't check if the fridge light is on without opening the door (which of course turns it on), it's hard to know if a system is resilient to failure without having one. It just might be that there hasn't been a situation that would cause a failure.
