Comment on When Pi-hole is down?
AndiTails@lemmy.world 4 months agoRun two and check the logs. You’ll see about 20% of your requests will log on the second instance. So currently, that’s 20% of your DNS requests not being filtered.
You’ll also find some devices just latch on the the second and never use the first - again, in your scenario, these are not being filtered.

I can back this up with experience.
I'm actively running two piholes for years now. About 2/3rds of my traffic does go to the primary and some seem to 'lock on' to using just one, but most devices will swap between the two at their leisure.
