FromSoftware says the game servers for Dark Souls 2 and Dark Souls 3 are temporarily unavailable on all platforms because of a server issue. The studio hasn't said what the issue is.
There's no return time yet. FromSoftware says it will post updates once it has information on when the servers will be restored. Until they're back, the games' online features are down. Eurogamer also reported the outage.
