I think that what you probably meant to say was:
"... outsourcing to Affilias, Amazon Route 53, DNS Made Easy, DNS.com, 
Dyn/Dynect, EasyDNS, GoDaddy, Netriplex, UltraDNS, Verisign, Zerigo, etc."

^^ Those are the commercial anycast DNS services that I know of 
presented in a simple non-preferential alphabetical order.

I happen to know, because I did parts of the implementation, that DNS 
Made Easy provides anycast IPv6 DNS to all customers (available on all 
servers if they like).
