I like to say that if its not actually getting traffic, its not actually working. Or really, if its not serving traffic, you don't know if it will do it correctly, so just don't expect that to be the normal situation. Though, of course, you then have to pay more attention to the load you can handle, since you need to make sure that you have the capacity in case of failures, instead of just having 2x capacity as stand-by... ie, real capacity planning instead of just adding resources when there's a problem.
