You do have two DNS options on most devices.
A Primary and a Secondary. If you’re worried about your primary’s stability/reliability, put a different dns as your secondary that you trust.
Not really. I maintain backups (one local, one offsite, one snapshotted and stored on a flash drive I carry around with me) of everything at home, including my OpenWRT devices and the configuration of my Pi-Hole. The Pi-Hole is running on an SBC so I also periodically take local images of it with dd in case I need to write a new microSD card and boot it up. I’m not the only one at home that relies on a net.connection every day, so I have to take other folks into account for resilience.
It’s not hard to setup a pi as a backup DNS on your local network, but how I’ve setup a few friends who have limited hardware is to have the primary DNS as the local adguard and the secondary DNS as adguards public adblock DNS
That way if the local falls over, you still get some as ad blocking from their public one. If your setup allows it, they also have a public doh and dot encrypted dns for a bit of privacy
Are you guys not concerned about losing complete access to the internet if something drops on your server?
I realise these will be very rare cases, but shit happens sometimes, and always seems to happen at the worst possible moments.
What’s your recovery plan?
Edit to add that this is the reason I’m on nextdns… Make it someone else’s problem
