Can you say more about your experience with AWS support? My experience has been consistently quite bad. I've had to resort to AWS technical support perhaps a dozen times over the last few years. They're always slow to respond (even if you have an SLA promising otherwise), and it always takes half a dozen go-rounds to get to a resolution. They will stick with you until the issue is resolved, but they don't add much value along the way. It's a slow process of "did you do obvious thing X" (even if you've already provided facts indicating that couldn't be the problem), "please provide six different pieces of information" (that don't seem to bear on the actual question), and "I've never seen this before, let me go research it".
