In fact, if you use Route 53 with an alias to an ELB, the TTL is hard-coded at 60s -- it is not even configurable. If it were, we'd follow the practice of lowering it prior to changes, and raising again once things or stable, but as it is, that's not an option (moving DNS off AWS would be a hard sell, not cause it's terribly hard but afamic, there's not really any value to doing it).
