If you want to remain playing - for next at least 1 hour (notified longer if problems still persist) stay logged into minecraft - the sessions are down. You may learn more here: http://help.mojang.com/ *Should be fixed now - Try closing minecraft, and then rejoining.*
right - you're able to log into your account, you can see the servers up... but you can't join a server - you'll most likely get the connection lost error message.
As long as you don't log out - you should be fine... Also: Hoorah my 1000th post - and now i have all trophy points success
I just discovered this a few minutes ago. someone on each server should post a link to this n chat t let the other players online know.
