Minecraft Uptime
by Gvach
Minecraft Uptime is a Fabric client mod that checks whether websites are reachable while a player is in the game and reports outages in chat.
What it does
Players can list the sites they want to watch in the mod's configuration file, along with how often each check should run. While the world is loaded, the client checks each listed address at that interval, so a site that goes down during play is noticed without leaving the game. The mod is client-side only, so only the player who installs it needs it and a server does not have to run it.
When a monitored site becomes unavailable, the mod sends a notification to the chat, accompanied by a distinct sound. The list can hold up to 60 sites, and each entry is set with a name and a URL. Minecraft Uptime is published for Fabric only, with a single build, 1.0 for 1.21.4, under All rights reserved, so the code is not open source.
Key features
Periodic site checks
Each listed address is tested at a set frequency while the world runs, without any command needed.
Chat outage alerts
A site that becomes unavailable triggers a chat message and an audible cue during play.
Named site list
Every entry in the configuration pairs a display name with a URL, making it simple to tell sites apart.
Up to 60 sites
The configuration accepts up to 60 monitored addresses, each with its own check frequency.
Configuration file
After the first launch a mc-uptime.json file appears in the game's config folder, where all settings are edited.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Watching a home server
A player running a server or web service on their own machine can list its address and hear about an outage without alt-tabbing to a browser.
Following several services
Players who depend on multiple websites while gaming can track them all from one list, up to the 60 entry limit.
Who it’s for: The mod suits players who want to know about website outages during a session, and anyone who hosts a service they check regularly. Because it is client-side only, it does not need to be installed on a multiplayer server.
