Having two main servers hosting Pi-Home works great - until both of them are offline for any random reason. So I added a third Pi-Hole following Techno Tims easy to follow guide. By using keepalived and VIP I can update, restart and tinker with the two servers as much as I want. https://youtu.be/hPfk0qd4xEY



But what if all three go offline for any random reason? Are you planning to add a fourth?


It’s pi holes all the way down.


Obviously the fourth instance should be hosted on AWS connected to your local Tailnet.


But what if AWS has an outage as well?


Are you really web scale if you aren't multi-cloud with accounts in GCP and Azure?


Alternatively - if someone want to deal with setting up Keepalived and VIP - they can use GravitySync. It's a easy setup.
