It seems like concern over reliability of the PiHole is a common concern (between the original post and the comments). I guess I'm just not sure why. I just run one, and have for quite a while. I've never had any issues, which suggests to me that the probability of failure is pretty low. But more importantly, the impact of failure is (in my opinion) almost zero. It's a home network. If the PiHole has a problem, either fix it, or change your DHCP server to hand out a different DNS server and renew a few leases.
If you have other, less technical family members on your network, this becomes a bigger problem, especially if you work from an office or take business trips.
What’s a 60 second side quest for us is a “wifi’s down” for them. (Any outage at my house is reported as a WiFi problem.)
I’ve had problems a couple of times in several years. Part of the issue is that it is rare—so that when it does happen, I just figure the ISP is being flaky instead of my mind immediately jumping to DNS problems.
