Is the server down or undergoing maintenance?
I've been ok connecting for the day and after I disconnect for a bit, it's not letting me join :/

 

SkyBlock.net is currently down.

 

Alright thanks. Any link where we can see it's status or an eta?

 

any website that shows servers usually have a bit saying - server: offline/online
you can see it here -SkyBlock.net | Minecraft server
