From Wildcard:
“With the launch of ARK: Survival Ascended at the end of August, we will sunset all official servers on Xbox, PlayStation, and PC for ARK: Survival Evolved—at that time, the final save-datas from the ARK: Survival Evolved official servers will be uploaded for players to re-host on their own servers or play in single-player/non-dedicated, as well as slightly earlier snapshots. You will still be able to play on single-player, non-dedicated, player-dedicated, and unofficial servers.”
