[dns-operations] OpenDNS, Google, Nominet - New delegation update failure mode

[Doug Barton]

Puneet, or anyone else at Google, are there publicly available 
references to this configuration choice? Web searches have all returned 
pages of generic discussion about parent/child config. I'm having a 
discussion with some colleagues and it would be helpful to reference 
something official.

If anyone from Nominet, or Knot, or other folks who referenced that 
their software is also parent-centric have references, that would be 
helpful as well.

Best regards,

Doug
