Running multiple Pi-hole servers has always been a challenge, until now. In this video, I’ll show you a tool called Nebula Sync that helps keep them in sync, making DNS and blocklist management much easier. I'll walk through how it works, how to set it up, how to choose the right settings, and why it might be useful for your network. This is a follow-up video to my other popular High Availability Pi-Hole videos but for version 6 and up!
