I would also recommend turning down the TTL for the zone to something 
short, like 30 minutes or an hour prior to removing the entry. Prior in 
this case should be twice whatever the current TTL is to make sure that 
all cached copies have been refreshed with the new short TTL.

That way if you do kill something critical then there will be less 
disruption when you put it back in.

Good luck :)
