ATM10 8.4 was published on 29 October 2026. Its official server archive is ServerFiles-8.4.zip, listed under Additional Files on the 8.4 release page since 1 November 2026. Download that archive for a server, rather than the smaller client pack.
Our All The Mods 10 server hosting page shows the hosting options. Before using an installer or moving a world, confirm which pack version it installs. A new release on CurseForge does not mean every hosting template has updated yet.
Where to download the ATM10 server files
Open the official release for the version your group will play. Under Additional Files, choose its matching server pack. The checked 8.4 page lists ServerFiles-8.4.zip at about 1.26 GB. The main All-the-Mods-10-8.4.zip download is the client archive.
Match the exact pack version on the server and every player's launcher. Keep the release page bookmarked so you can check the maintainer's files again before the next update. Avoid repacks and do not rename an older archive to look current.
Match Minecraft, NeoForge and Java
The 8.4 release identifies Minecraft 1.21.1 and NeoForge 21.1.265. Older instructions for 8.3 refer to NeoForge 21.1.259, so do not carry that old loader forward when moving to 8.4.
The maintainers' Java guide maps Minecraft 1.21 to Java 21. Check the runtime used by the server process, including its container or panel startup setting. The Java version on your own computer does not tell you which one the hosted server uses.
Check what your downloaded archive contains
Read the instructions supplied with the server files before changing startup settings. Use that release's scripts and installer rather than copying an old launcher command. Do not upload the client's entire mods folder as a replacement for the server pack.
We opened the 8.4 server archive on 1 November 2026: startserver.sh installs NeoForge 21.1.265 and asks for Java 21, user_jvm_args.txt sets -Xms4G -Xmx8G, and the mods folder holds 469 jars, the same number as 8.3. If your server has more than 8 GB of RAM, raise -Xmx in user_jvm_args.txt to use it.
Prepare a recoverable update
Stop the server and keep a separate backup before replacing files. Save the world, configuration changes, scripts and access lists needed to restore the previous setup. Keep the previous pack files and record the working pack and loader versions.
Do not overwrite that copy during the update. An untouched recovery point is useful if the new pack, an extra mod or your custom configuration does not work together. The ATM10 update guide covers the update process.
Install using the matching server instructions
Follow the official server guide for the archive you downloaded. For a fresh local installation, it describes extracting the server files, running the supplied startup script and accepting the Minecraft EULA before starting again. Let installation finish.
On managed hosting, check the loader and startup settings with your host before substituting scripts. If you are updating an existing world, review the guide's update methods first and apply your own configuration changes deliberately.
Test before opening the server to everyone
Use a copy first. Read the startup logs, join with the matching client and inspect the parts of the world your group uses. A completed download does not mean your existing world, extra mods or custom scripts are compatible.
Check memory use during actual play rather than treating a pack filename or a player count as a capacity guarantee. Keep the community on its known working version until the updated copy has passed your checks.
Choose a location for your group
Space-Node offers Minecraft regions in Europe, North America, Singapore, Mumbai and Australia. CPU resources on game plans are shared and checkout bills in EUR. Compare the displayed resources, region and total before ordering.
For groups around Australia or New Zealand, see the Sydney Minecraft guide. For Singapore and nearby Southeast Asian countries, see the Singapore Minecraft guide. A region choice does not guarantee a particular ping or tick rate. Confirm the location in the order summary and the pack version in the installer before moving your world.
