Test servers would be live till the game release
Today the PUBG devs announced they would be not shutting down test servers
Most of the players who already tried the new map were really excited about it. The game developers decided not to follow their schedule and leave the test servers online till the game would be released. Everyone is free to learn the new Miramar map with all possible game modes. See the full changelog here.
Players, the test servers will stay open until PC 1.0 comes out on live servers! The transition to Phase 2 will be relatively seamless and there won't be any downtime today. There will be maintenance periods to deploy patches as needed. We highly appreciate all your help.— PLAY BATTLEGROUNDS (@PUBATTLEGROUNDS) December 11, 2017
