And about routing. And anycast. And real-world operation of large DNS  
infrastructure. And to speak from *personal* experience.

You spout statements regarding "sufficient" or "adequate" numbers of  
resolvers, service addresses, etc. as if you actually know. So let's  
cut to the chase: How many service addresses are sufficient? Provide  
the methodology and research to back it up. And "It depends" doesn't  
cut it. You're making statements based on real word implementations  
without any qualification.
