D2R servers are down (Diablo 2 Battlenet is Down) on PC, PS4, Switch, and Xbox One. Since the last update, players are experiencing a number of issues when they trying to play online. Out of those affected, some are experiencing login and character deletion issues. You can check D2R server status, maintenance, and downtime details here.
Since this morning D2R servers are down. However, your characters are safe. If you were just playing the past few hours there will be a server rollback – you may lose recent progress. If your Horadric cube was in use during a server crash or game crash, it messes with the save state. The cube and anything in it may be gone. You can get a new cube by running the Halls of the Dead in Act 2 and getting a new one from the chest.
Blizzard posted the following:
