   You can use dnsdist as your upstream for load balancer and failover

   If you connect to only one dns server(dnsdist) then it is a Single Point of Failure.

   Nginx will not know whether DoH Proxy 1 can resolve or not if DNSdist 1 dies. Therefore, in case of a fail, it will still route traffic to the "faulty" DoH server.
