I am surprised that Netflix uses UltraDNS when they use AWS and they could be using Route53.

I would imagine they don't use it for exactly that case. Imagine a case where most of AWS is having critical problems, you would want (at the very least) control of your DNS to attempt a partial recovery of service for some portion of your customers that have providers who respect DNS TTL's.

Running my own DNS servers. But having issues with clients using Rackspace Apps - hosted email (still down due to UltraDNS).

Would there be anything against using multiple large anycast DNS providers?

Netflix is 100% dependent on AWS for infrastructure. If AWS is having problems, there is nowhere to redirect to.
