Fallback Minecraft Server

A plugin designed to keep players connected when a Minecraft network is temporarily unavailable. Instead of disconnecting players when all fallback servers are offline, mc-fallback transfers them to a dedicated fallback service and automatically sends them back once their original server is available again.

Supported platforms and versions

• Velocity Versions: 3.5.0 - 4.1.2
• Paper - Versions: 1.21.10 - 26.2

Although mc-fallback may work on other platforms or versions, I do not guarantee their stability or functionality.

Setup

1. Download the latest version of mc-fallback.
2. Place the plugin in the /plugins/ folder of your server.
3. Enable accept-transfers in your configuration.
   • (Velocity) Enable accept-transfers in your velocity.toml.
   • (Paper / Purpur) Enable accepts-transfers in your server.properties.
4. Restart the server.

How it works

When a player is disconnected from a server, mc-fallback first checks the fallback servers configured in Velocity. If none of them are available, the player is transferred to the external fallback service instead of being disconnected from the network.

While waiting, the player receives a visual status display showing that mc-fallback is attempting to reconnect them. As soon as their original server responds again, the player is automatically transferred back.

Players are also transferred to the fallback service when the Velocity proxy is shut down. This allows network maintenance or restarts without immediately disconnecting every player.
