Two outgoing queries for each incoming query
Is this possible with 9.6.0-P1 or do I need to change the code (all ideas where to start are welcome, I haven't looked at the code yet). I want to setup a forwarder and each incoming query (in fact only A or ) should be sent to two different upstream servers.

If there are two (or more) servers serving a zone, it will already query all of them for the initial query. However, it uses the answer from the server that has the fastest response time.

No. It will query multiple servers in turn as needed to satisfy queries. RTT estimates are most effective with infrastructure zones as those are the ones queried most often. Named tries to minimize the number of queries it makes.
