-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Normally, queries are sent to just one server, but every so often, a query is sent to both servers, to see which on answers first. The server which answers first is used until the next time the test is done. If a query times out, the retry is done to both servers.
If your "bad" server never answered, it would be ignored, but if it answers some of the time, that's a problem. A solution to try is the dnsmasq --all-servers option. Cheers, Simon.
