Guys,
This isn’t just USEast that is down - ALL Realms of Diablo 2 cannot make/join games at all. USWest Europe and Asia are also affected. Did someone flood or DDoS the game servers? It sounds like this is happening or something. All you get is a line waiting screen that never creates any actual game, and to try to click join a game, you get “No New Games can be created right now. Please join a game or try later.”
Repeat: THIS IS HAPPENING ON ALL REALMS.
