I’m not exactly sure how many queries, but it’s above the free limit. I purchased the pro plan. For $20 a year and it’s been a great service for me. I can send a referral code for 30% off (I think). I think adguard has a similar service.

I don’t think this accomplishes what he wants. The router DHCP will assign the second DNS address as you mention, but the devices will select one at random, not as a backup/failover. So what happens is that devices sometimes go through the Pi-hole and sometimes go through the secondary DNS address and receive ads. The only real way I’m aware of is to have a second pi-hole for redundancy. Personally, I decided to use a cloud based service (NextDNS) for this exact reason. I didn’t want my families internet to rely on devices that I host.

I have a similar setup to the above. Personally I use Docker Compose and backup up my compose scripts to the NAS.

If that’s the actual name of the fruit, why wouldn’t it be marketed under that name?

Out of curiosity, how do you accomplish that?

That last paragraph is great advice. I get so frustrated at times. Sometimes it feels like I need to fix things ASAP when I’m reality it doesn’t matter. In many cases coming back with fresh eyes helps considerably.
