Hy everyone, I have a PiHole instance running on my home server, and I changed my router (Fritz box) DNS in order to use my PiHole. Everything runs great.

I was wondering if I can put another DNS provider on my "alternative DNS server" in my router, in order to have a fallback alternative in case my server is down, or if I should avoid it.

I'm asking this because I don't know if the request will be handled in parallel between the two DNS provider (that would make my PiHole useless) or not. Thank you.

This answered my question. Thank you. I guess I will sacrifice redundancy

Or set up a second pi-hole.

I run multiple pinholes using keepalived. Then I only use one DNS in my DHCP server. Second pihole will seemlessly take over if the first one goes down whilst using the original DNS address.

Work quite well. I had to learn the hard way that only using a single pihole was just asking for my partner to be mad when it didn't work / when I was doing server maintenance. Now I have multiple and they can all seemlessly take over if any my server nodes are down

Keepalived is the way. Gravity sync keeps everything in line. Works like a charm. I migrated yesterday from wifi to wired and cannot be happier. As a bonus did not need to reconfigure pivpn.
