I disconnected and i cant rejoin, is that happening to everyone or just me?

Did you get an error?

I'm getting that almost twice daily irl. Generally, I find it helps to press Quit Game and then relaunch MC. Is it a Java Socket Error? That would mean your game crashed of too much lag or of bad connection.

It happened again D:

It looks like these posts are coinciding with restart. Every day at midnight and midday server time, which is about 2 hours ago your time and 10 hours time, the server kicks you. It stays down for approximately 1 minute and then allows you to come back on again. It is a quick on and off again of the server to help keep things running smoothly. There is a 5 minute warning from Broadcast every time.
