Good point, although that means maintaining another service on your own 
infrastructure.

Another thing that makes it hard for many companies to diversify their 
DNS providers is that they make use of DNS-based load balancing and 
failure (e.g. Amazon's Route 54, Akamai's Global Traffic Management). 
These services can't easily update each other.
