i would like to set my pihole to use the 1st upstram dns as long as its available and then change to use the 2nd when the 1st is unreachable.
i have set the below in a conf file to try to get this to work
strict-order
server=194.242.2.4 # mullvad
server=10.0.6.8 # DC
however after setting this the majority of the upstream dns do work as intended but i am still seeing some use of the secondary.
Is there a setting i can add to add more weight to the primary or give the primary more time to respond before the secondary is used?
