Because these types of problems never occur when you are running on bare metal? In fact it is worse: typically you are resource constrained as the budget cycle to buy new hardware doesn't start up till next quarter so you literally don't have another machine to run on so you are screwed. That isn't to say that AWS is without fault, but I find most comments about unresponsiveness of systems or the inabaility to find a route cause (i.e. A bad disk) would happen anyway with another system designed in the same fashion.
