Brad is wrong. It will try others if the first one does not respond.

Your local DNS provide authorative service for only your PCs on your
private network and recursive service for the rest of the internet.
Noone else needs to know that your server exists.

You don't need to ask any upstream servers for queries, it will do it
all itself and cache the responses it gets. We recommend against
forwarding queries except in special circumstances. DNS is truly
distributed, otherwise the internet would have collapsed a long
time ago.
