This is a server called MinecraftOffline and it runs Minecraft version 1.21.10. The world is permanent so your builds are meant to stay and you can keep coming back.
The server uses a custom plugin suite so it is not just plain vanilla. It is hosted on strong hardware with an Intel Xeon E 2276G two fast NVMe SSDs and 64 GB of DDR4 ECC RAM.
The server is based in Finland so players in Europe get really good performance and a fast connection. There is a Discord community where players can hang out and talk about the server.
It feels like a place that wants to be stable and long term so you can settle in and play without worrying about constant resets.
