what if Amazon DNS goes down? Doesn't matter how many zones you've got... DNS remains a potential single (yes it is redundant with HA), but it's still a single point of failure.

Super low TTL and Refresh combined with replication to a DR provider. High Availability placed exclusively on a single provider - even Amazon (albeit different AZ's) is of zero value if all of Amazon itself is offline...
