Quick anecdote.

After using pihole on an rpi2(!) for over 5 years, with the same SD card mind you, I have switched to technitium, and I'm not going back!

The switch happened when I boasted about my pihole setup to a colleague and how it's been robust for the last 5 years. After the video call, internet connection drops and I naturally suspect DNS issues. I plug jetkvm to the rpi2 and sure enough got a kernel panic, possibly due to a corrupt SD card 😅

I quickly deployed technitium on an LXC and been using it ever since! I'll probably move it to its own hardware sometime in the future.

I just wish it had a better mobile UI and it wasn't a single page app, which can be frustrating at times.
