I ordered a Raspberry Pi 5 so I have a Pi 3 that’s about to be redundant. I haven’t used Pi-Hole so I was thinking it’d be good for that but I’m curious if there’s any downsides for users. Are sites blocked if you dont whitelist them? That sort of thing.
Basically, I’m not worried about me having issues but I’m worried about a maintenance headache if friends and family can’t access things.
You have full control over what you block and whitelist. So if anything goes wrong, you can just troubleshoot it and whitelist if needed. If all fails, you can always (temporarily) turn off all blocking in pihole.
“PiHole Browser Extension” in Firefox is great for temporarily suspending the Pi-hole altogether and automatically re,-enabling it after a set amount of time. It’s especially handy if you run multiple Pi-holes for redundancy.
