I think the general problem space of how we distribute authoritative data to caches is well worth thought and investigation. The model "if you want good end-user performance, you need to anycast your authority servers all over the planet or pay someone to do it for you" is a poor one, no matter how much we enjoy it at Dyn.

This document is thinking in that direction, but it is restricting itself to what is arguably the best-served DNS zone in the world, with the most spare capacity in its infrastructure, and which is least in need of improvement. Generally, I am against adding complexity without benefit.

I continue to be concerned that slaving the root zone on (or near!) validators smells like a configure-and-forget project for some sysadmin who has since left the company, and the people left are only one firewall rule change away from weird troubleshooting nightmare. I agree that carefully documenting how this should be done is better than leaving those people with no documentation at all when they need it at 3am.

I think the document is well-written and clear, but that it needs the risks (non-zero) and benefits (near-zero) to be clearly discussed, and to avoid any unwarranted suggestion that doing this is sensible in the general case.

So...

... +1 to Wes' conditional support above.

I will review, contribute text when not swamped by other things, etc.
