Summary of announcements about the servers for Xbox only (PS4 has already been announced as being NA-West, new server in Chicago)

15May: https://console.worl...consolidation/

For NA West players on Xbox: NA West will no longer be available in the launcher for Xbox One and Xbox 360. Players who usually use this server will be automatically directed to NA East to play. This happened with our scheduled Tuesday restart on May 15.

For NA West players on all platforms, including PlayStation®4: NA West will no longer be available for all platforms. All players who use NA West will be automatically routed to the new NA East server, located in our brand new Chicago data center. This will occur a few days later once we ensure stability. Stay tuned for more information.

20 June: "As part of our planned server upgrades the NA West server is again available and the NA East server has been de-advertised for Xbox players . While we expect smooth performance please let us know of any issues."

PS4: The new Chicago server, NA-East, is actually NA-West, according to the WG RU announcement. Which conflicts with their 15May announcement stating NA-East is the new Chicago server.

Xbox: NA-West being used while they upgrade NA-East (the new servers in Chicago).

It makes total sense now!
