Mud blocked by internet company. Help?

I play a Mud that was just recently blocked by my internet company. I've played the damn game for 6 and ½ years and i'm even paying for it now and they just blocked it about 15 days ago. I can start the game enter my pass and choose what character and after that it's says waiting while connecting to the game world. My friends sees me as online but i only see the loading screen. Is it any way i can breach the block or demand them to unblock it?
