Slaving the zone into the same view/instance as the recursion has the

instance will cache all of the queries it looks up. Currently the TTL

Accurate summary, but as this is the same behavior as you get when using
traditional root servers, I'm not sure it makes sense to characterize
it as a disadvantage.
Well I tried to be neutral about that, for just the reason you mention.
(I don't actually call it a disadvantage, I just point out the
behavior.) To be fair, I think it actually *is* a disadvantage, so
perhaps my thoughts on that are clouding my ability to be objective.
How about adding the following to the second-to last sentence, "...
looks up, as it would using the traditional root hints method."
Does that sound more balanced?
