Diablo 1 multiplayer


I can't seem to get on battle.net anymore. Just one day out of the blue I can't get on. I try and it says it's connecting to the fastest server and then I get a message saying I must be trying to connect to a dead server. Last time I checked it was being hosted by AT&T, is it just my comp or did Diablo 1 multiplayer disappear? It's an old game so I'm asking to be sure.
