Sony announced that they'll be shutting down Gran Turismo 6's servers in March 2018. The distribution of downloadable content for the game will end on 31 January 2018. The offline portion of the game will remain available to players.
Gran Turismo 6 servers are about to go live at a nice little farm upstate. They will be joining Killzone 2 and 3's servers. You see, Sony has announced that Gran Turismo 6's servers will be shutting down in March 2018:
"On 28 March 2018 at 12:00 UTC, the online services of the PlayStation 3-exclusive software "Gran Turismo 6" will come to an end. Prior to this on 31 January 2018, we will also end the distribution of downloadable content that can be used in-game."
The racing game was released back in 2014 and has since seen some massive improvements that have been coupled with tons of free content. After the servers are gone, the offline portion of the game will remain available to players.
Alas, newer modes such as the Community, Open Lobby, Quick Match, and Seasonal Events will all be shut down. This also includes the GT6 Track Path Editor that is currently available on Google Play and the Apple Store. These will be cut on 28 March. Also, you won't be able to transfer your track data from the app to GT6. You should redeem all credits you purchased online before the servers go dark.

Gran Turismo Sport is the latest addition to the series. The new game was published by Sony in October, 2017. It includes two game modes: "Sports Mode" and "Arcade Mode". Gran Turismo Sport does not offer the same dynamic weather system and day-night cycle that was present in Gran Turismo 6.
