Elden Ring: Nightreign has 2 server regions worldwide.
Japan
Japan Very high population Separate matchmaking zone. Cross-Region toggle controls whether Japan players match with non-Japan players. Japan has the largest Nightreign player base relative to other regions. Rest of World
Global (undivided) Very high population All non-Japan players share a single matchmaking pool. There is no subdivision between North America, Europe, and Asia — this is the root cause of chronic cross-continental matchmaking. Disabling Cross-Region does not create finer regional pools; it only separates Japan from the rest. Connection: Peer-to-peer (P2P)
Game sessions are hosted by one of the players (the "host"). Your ping depends on your connection to that player, not to a fixed data center.
