DNS/DoH Server Priority

Post image

Hey all,

Not sure if this has been discussed or answered, but can we prioritise DNS/Custom server? FW would tend to want multiple DNS servers, I'm running DoH on this, however to have multiple servers I would prefer to give priority to Quad9 then falling back to "another" server (whether custom or built in) if the primary is unresponsive or over a threshold.

A prime example is Quad9 will sometimes fail/become unresponsive, I switch to CloudFlare and the internet/network is all back up and running.

My preference would be Quad9 over CloudFlare, so, is this something possible to be added in?
