I found the Kere server and it is a hardcore survival server but it plays really different.
There are no structures and no hostile mobs spawning so the danger is more about staying alive in hardcore while you explore and build.
The terrain generation is made to feel like continents instead of one giant landmass and there are a bunch of small features to discover.
It is on Java and it says version 1.21.11.
If nobody is online the server can go into sleep mode and you just wait in the lobby until it boots back up.

GG.MINEWIND.NET New Server IPONE LIFE Hardcore Vanilla No Mercy

Ultimate Hardcore is a hardcore vanilla survival server where you only get one life. If you die you are done so every fight and every cave run feels serious.
It has no pay to win stuff and it does not do resets. It also does not allow alts so you cannot dodge the rules.
The rules are pretty simple. No cheats. But griefing and PvP are allowed so you have to watch your back.
The dragon egg is still not taken yet so people are still racing for it and trying to be the one who gets it first.
GG.MINEWIND.NET New Server IP2K Border Super Hardcore Challenge

This is a hardcore server where the owner made the mobs way tougher and scarier. The whole idea is to push difficulty as high as possible so every step feels dangerous.
The world has a tiny 2k border. That means you do not get endless land to run to. You have to fight for space and learn the terrain. There is no easy escape and every chunk actually matters.
If you like clutch plays and intense fights and you do not mind losing your stuff when you die this server feels perfect. It is made for players who want a real challenge and not a chill hangout.
There are no extra details listed about rules or versions so you just join knowing it is hardcore with modified mobs and a tight world border. If you can survive here you are actually good at Minecraft.
