The thing is, all our cloud instances were redundant so SL downtimes almost never caused real service disruptions on the site. But when one instance dies, there is a huge chance that other one (two, five, ten) will die soon as well. As for the automated kill/deploy scripts - really often even their own cloud-related portal features don't work (like when you try to restart/reset an instance and their APIs and portal just time out, etc).
