I have an asus router with a pi-hole on the network.
I was doing some work on my server and noticed that when pi-hole was down, I couldn’t access the internet. I was looking for some ideas online how to deal with this, but they said to have a second pihole on the network in case one is offline. Is that the only way to do it? Is there any way to have the network go back to normal if the pihole is offline?
If your DNS sinkhole is down, your modem/router/host operating system settings (and even the PiHole itself) should allow a fallback. If you didn’t set that up and don’t know how, then you should consider not using Pihole until you know what you’re doing.
The ONLY DNS server you should have set on your network is a/the PiHole(s).
You still should set two dns servers… Two piholes/adguards
