One could also encourage folks to use different name servers for caching and not allow recursion on their authoritative servers. That way if they claim to be authoritative and they are no longer, nobody cares. I seem to remember having a discussion about this very thing with a large provider about 6 years ago and they were not interested in any form of co-operation that would prevent client internet experience being broken when a change of delegation took place. They didn't have the capacity to understand the problem let alone a resolve to solve it. I wonder if anything has changed :-) regards Peter Mott -/-

I believe this is now considered best practice :^)

That sounds exactly like the discussion we had with them... Thanks for the feedback, much appreciated - I'll ask them again then. Regards, Gerard
