Live status
Check whether it's online first.
You might get lucky.
Official live server status
One click before the launcher ritual.
Open the live status page, check the server response, then decide whether Fabric deserves your attention today.
If the answer is no
Downtime has a changelog too.
When the status page says no, the official updates feed is where 6b6t posts outages and return notices. That is the useful part of the server's commitment to transparency; the rest is refreshing with purpose.
Connection check
Online is not the same as reachable.
If the live page reports the server online and Minecraft still declines, head to the join troubleshooting steps. Java needs AnarchyMod; Bedrock needs the correct host and port. The server's favorite puzzle is not necessarily yours to solve.
