Since i happen to be on a DALnet server as we speak, i must once again disagree with you. The site you meantioned i believe is checked once a day (altho im not positive about that) and with all thats happening, the status of any server(s) can change from moment to moment. It is more than possible that at the moment that website checked, there werent any servers up. Please also be aware that some of the servers listed on that site were delinked a good bit ago so would of course show as dead.
Be patient and have a little faith
