Why does AWS Route53 not keep consistent DNS zones?

Question

In a setup with EC2 instances, and a properly configured zone file, I've found that AWS periodically changes their DNS servers. This means one has to go all the way back to the initial ISP setup and update those DNS records every time they change.

This ISP (and most every ISP) actually allows you to set up private DNS nameservers, but this only works if the DNS servers (addresses) are consistent. Otherwise the site will become completely unreachable when AWS randomly changes their zone files/DNS servers. Is there any way around this?

Answer 1

The IP addresses of Route 53's name servers assigned to your hosted zones should not change. I would post to the Route 53 forums explaining what you are seeing.
