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?

    On Mikrotik I have a script that runs every 30sec. If pi-hole not responding, router switches to public cloudflare dns records, otherwise to pi-hole IP.

    This setup works like a charm.

    P.S. I am using Blocky, but it’s almost the same as Pi-Hole.

      That sounds cool. I’ve never messed with scripts on Mikrotik, but would it be possible to share what you have?

      I’m guessing a relatively short DHCP lease time is also in play so devices can get the new DNS address? Or do you have Mikrotik set as the DNS server?

      Thanks, this looks good, but I’m not sure I can do it on Asus. I’ll look into it.

      Seconding the request to share your work.

      That is an amazing idea you’ve come up with that I never considered, but now I need it.
