Been running a pi-hole with unbound for years here. Apart from updating the roots file every six months its been sitting there doing it’s thing happily without skipping a beat. I did take a small look at Adguard but couldn’t see anything like the tail pihole log option which I tend to have in a tab as I like to see what’s going on.
Hmm they not been round one of our camp fires… They hot like the sun. Let’s just say there’s actually a Couple of Nasa needs that love riding dirt bikes and like to make HOT fires. Not sure what 90 of the stuff is they bring but makes for fun weekends :)
