If the record is dropped, a new query should look it up freshly. Make sure 
all the auth NS are in sync - the secondaries have to be hupped too.
Are all your servers answering correctly and up to date?

The TTL is cached as well in the name record, so the effects of changing 
the TTL have the same propagation delay.
