I got perm-banned on that server 2 years ago, so I don't know what the problem is with the server. I recommend checking another server to see if it says that when you try to log on. If it does, it's most likely your internet.
I know the feeling mate. I always have terrible internet. It has been bad on every server I have ever been on. Always dropping down to one bar in the name listings. I wish there was something I could do.

One of the most amazing tools you have at your disposal while troubleshooting a problem is, in fact, restarting the game. If that doesn't work, try a different server, as was posted above. Then try restarting your computer, and then finally redownloading Minecraft. If none of that works, then try the forums again!
Also, the most knowledgeable people for Minecraft support reside in the Support section. If you have another problem, you'll probably have more luck there than anywhere else.
