Okay thanks till I think I got it. But don't DNS servers cache NS records only and not the entire DNS zone?
The records were cached, as a external server normally does not know which records exist in a zone.

Will changing the ttl to a shorter time make any difference?
Yes. But not all external servers will care about that.
