We automatically restart our servers every single night for performance and updates. Restarts lasts anywhere from 30 seconds to ten minutes and do not affect player progress in any way.
You are on an outdated or too updated version of Minecraft, please contact support if you are not sure.
Downtime or Maintenance
While this does not happen often, sometimes we are down for maintenance. This means our servers are temporally un-join-able. Usually we would clarify this when you attempt to join the server, and we would always announce it on our Discord.
