Astroblock Server Hosting

Astroblock is a space skyblock pack by knoxhack for Minecraft 1.12.2, sitting at over 600,000 downloads on CurseForge. Instead of the usual dirt block floating in the void, you start on a small space station in the asteroid belt with almost nothing, and the pack's progression is a route through the solar system and eventually back down to Earth, where a set of overworld dungeons waits.

The framing changes how skyblock feels. In a normal skyblock the void is empty scenery; in Astroblock the space around you is the content, with custom asteroids and structures to reach once you can survive outside your station.

Astroblock is quest-driven. The quest book is not decoration — it is the only reliable map of what the pack expects from you, because a space skyblock has none of the landmarks a normal world would give you. Early quests cover resource generation from nothing, then life support, then getting off the starting rock.

From there it turns into a tech pack: power, ore processing, automation and rocketry, all in service of reaching the next body in the system. Groups that split the quest chapters between players get through it far faster than groups where everyone follows the same chain.

Astroblock runs on Minecraft 1.12.2 with Forge. The most recent build is the Astroblock: Reloaded line, last updated in 2022, so the pack is effectively finished — which for a server is an advantage. Your world will not be invalidated by an update mid-playthrough.

As with any Forge pack, client and server must run the same pack version. Skyblock packs are particularly unforgiving here because a mod mismatch can corrupt the custom island generation rather than simply refusing the connection.

Skyblock packs are usually kinder to a server than open-world packs because there is far less terrain to generate and keep loaded. For a group of two to four, 4 GB is enough. Five or six players with separate stations and automation running are comfortable at 6 GB.

The load profile shifts in the late game. Once every player has ore processing and item generation running around the clock, the server spends its time ticking machines rather than terrain, and that is where a fast CPU core matters more than a bigger heap.

• Create a Minecraft server on your plan and pick a nearby location.
• Open the mod installer and choose Astroblock; the pack and its Forge build are set up automatically.
• Wait for the first start to complete — the pack generates its custom void world on that run.
• Do not regenerate the world after players have built. Skyblock worlds cannot be reset without wiping everyone's islands.
• Send the identical pack version to every player before they connect.

This is the decision that shapes an Astroblock server more than any setting. A shared station keeps the group together and makes the early resource crunch much easier, but it means one person's automation experiment can flood everyone's storage. Separate stations with a shared trade hub is the pattern most groups settle on after the first week.

Space skyblock leaves no margin for error: fall off the map with the wrong gear, or break the wrong block in your generator setup, and there is no forest to go rebuild from. Take a backup before any large machine build, and again before anyone launches for a new planet.
