This is a StoneBlock 4 server running on Minecraft 1.21.1 and it looks really stable. It uses self hosted hardware in Europe with 16 cores and 32GB of fast ram and the owner says it holds around 20 tps on average.
The server is hosted in Belarus and also has a proxy tunnel through Germany. That means ping should be better for players from the US and from Asia so more people can play together without lag.
There are fancy progression based ranks that you unlock as you advance in the pack and they are connected with discord. So the more you play and move through the modded progression the more ranks you can get.
The world is new and started on October 30th so it is still pretty fresh. It is a modded survival server so it is mainly for people who like StoneBlock style grinding and progression with good performance and a small growing community.
