About PrivateChunks
Three modded Minecraft worlds you just join and play on. We run them on our own hardware: All the Mods 10, ATM10 To The Sky and FTB StoneBlock 4. We take care of updates, backups and crashes. You pay one subscription, sign in with Discord and play on any of them, with up to 20 players per world.

Who runs it
One person runs it, which is why each world is capped at 20 players. If something's wrong, you'll know who to talk to.
The worlds so far
- ATM10 opened: All the Mods 10 on Minecraft 1.21.1. The original world, where most of the community started. 27 GB of builds, still kept.
- FTB StoneBlock 4 opened: FTB StoneBlock 4 on Minecraft 1.21.1. You start inside solid stone and dig out your base. There's no terrain generation, so the world stays small enough to keep.
- ATM10 To The Sky opened: All the Mods 10: To the Sky on Minecraft 1.21.1. All the Mods 10 as a skyblock. Same 400+ mods, but you start on a small island in the void and build outward.
- NextMembers vote on the next pack. It opens beside these, and none of them is reset to make room.
How it's run
- The stats come from the server
- A small program reads the server's own statistics files about once a minute. The website can't touch the game files, so nothing on it can be edited to look better.
- When the server lags, we find out why
- A watchdog spots lag that lasts, profiles the server for 30 seconds and reports what caused it: a machine, a mob farm or a chunk.
- We keep the config up to date
- In this pack, a reactor meltdown could break claimed land through the protection that's meant to stop it. We found that and switched it off before it hit anyone.
- Records get announced
- When you pass someone on a ladder, the Discord posts it with both names.
How the figures are read, and the small programs that run beside the worlds, are on How the stats work.
What we won't promise
What we do promise is on the front page.
We don't give an uptime percentage or promise it'll never lag. We can promise 20 slots per world, because that's a setting. Whether it ever hitches is something you'd see for yourself on your first evening.
Getting in touch
Message the owner in our Discord. It's run by one person, so that's who reads it.
