As I had to upgrade a bunch of Operating Systems as part of my regular system maintenance, I have taken advantage of my downtime and upgraded my Terraforming Mars server.
This server is the one I used for my digital birthday party back in 2022. It now has a proper TLS certificate (via Let’s Encrypt) and a real Internet solvable hostname.
This private game server can be reached at terraforming.operationalsecurity.es. You can use it without registration.
