Cant log in

Hello everyone, I'm having an issue, I've been playing on this server for a month now perfectly fine, not too big of issues. But now I've come a crossed my first technical issue, im trying to log on, my username and password are correct, but everytime i go to log in it gives me one of 3 different responses, 1. "disconnected from server" ( my internet is fine), 2 " unable to connect", and 3 logon server not found. Can anyone provide guidance on this ?

Login or world server's are down at the moment. Having the same issue on my end.

Okay I thought it was just for me, I'm not too worried then, hopefully it gets back up and running soon, thankyou.
