I'm having login issues too... Even with the use of server1.lolnet.co.nz As far as I can tell the server is online from the World Stats page, so does this mean a minority of users are running into troubles?
I think it would be easier if all the key server information was posted on the forums, either on like an important notices thread or just separate posts. Not everyone checks the facebook page for all the information you post there and rather we go through checking up on the forums.
