Well, yes, but there's another consideration at this point that I can

Why has it taken three hours for the slave zone to be loaded?

The answer to this is, of course, that no client has requested data from
the slave zone.  And if no client has requested data, does it really
matter that the slave zone is out of date, SO LONG AS the correct data
is fetched in order to satisfy the query.

I admit that zone transfers take quite a bit of time, but what's to stop
the secondary asking its primary for the *specific* information that the
client requested, or referring the client to the primary while fetching
the updated zone from the primary?
