I found a new game server hosting platform that is doing a free beta test right now. The beta is planned to be free for about three months.
They want people to spin up servers and test performance then share honest feedback. You can pick which node your server runs on.
The whole point is performance focused hosting with lots of headroom. They say they do not want to cram a bunch of servers onto one machine.
This might stay private and may never fully open to the public. The panel they use is pterodactyl and they are mainly testing systems networks and power costs.

I found a brand new UK survival server that is mainly here for stress testing and performance checks. The owner is mixing Azure hosting with Minecraft and wants players to jump in and see how it feels.
It runs on Paper 1.21 and the gamemode is Survival. The server is hosted in the UK on Azure UK South so it should feel snappy for UK players.
If you join the test server you are basically helping them push the infrastructure and report if anything feels laggy or weird. They also offer free 48 hour server trials for anyone who wants to try running their own server.GG.MINEWIND.NET New Server IP
