I agree it's a bug, but this is far, far more difficult to test against with a chaos monkey than one might think. With a whole datacenter down, not to speak of multiple availability zones, problems and dependencies will crop up that are extremely difficult to anticipate. Maybe you expected one other AZ to be up so you could provision servers from there, but now you have to somehow get one of them bootstrapped. Or maybe during the outage power was cycled on some equipment one too many times, causing some failsafe to trip, or maybe some of the core infrastructure like your switches and routers expect some core service to be up, but that core service can't get online without working network.
