How to set up a decentralized game/chat server (sh.itjust.works)

I've been kicking around the idea of running a server for games and chat woth some of my friends, but worry about everyone getting cut off when there's a disruption.

I've started looking into kubernetes out of curiosity, and it seems like we could potentially set up a cluster with master nodes at 3+ locations to hose whatever game server or chat server that we want with 100% uptime, solving my concerns.

Am I misunderstanding the kubernetes documentation, and this is just a terrible idea? Or am I on the right track?

And 4x chance of some of the hardware failing and someone needs to fix it. Unless I'm mistaken about how Kubernetes works.

I'm pretty sure half the point of kubernetes is to have the server automatically reroute traffic when one node goes down

But doesn't that require some software-defined networking or a special network setup? I'm pretty sure with the average home internet connection, you'll fail over to the replica at your friend's home. But that has an entirely different IP address and the game client will not handle that gracefully. It's going to disconnect. And you need to do some DNS as well to always point at the active server and forbid caching. In a datacenter or enterprise setting, sure. you'll just reroute the traffic and nobody will notice.
