Thanks, Justin.

We're already using an AT&T service that provides secondary/slave DNS
service for us based off of standard AXFR transfers from our master
BIND server.

I was hoping for something with a similar workflow, but the zone
changes would propagate to a global network of DNS servers available
via an anycast IP.

There are probably some other providers out there who do something
similar.  Route 53 is one I mentioned, but they have a custom API and
don't support AXFR directly.

Although, I did just come across this[1].

Thanks again...
