Multiple upstream servers

[kristoftorok]

Hi,

is there a way to specify multiple upstream servers and, in case of fail, switch to another one?

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

Hmm, I'll show you what I'd like to do.

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.
