> Having a single DNS server for your network is very stressful
Common... He's talking about a home network.
I also have one of my Pi set up as a DNS server (running unbound directly not PiHole though) and this thing is rock stable solid.
We're talking about Linux here. I've had a Linux server reach years of uptime (kids: don't try this at home, it's not secure but it was a test of Linux's stability).
Redundancy is great though but I really wouldn't lose sleep over it. If anything you can "dd" the Pi's SD card to another one and just replace the Pi (or the SD card) should anything go wrong.
