Ps4 – the PS4 Launch Edition

The saved game is stored on the hard drive, not on the physical disc. As long as you have a copy of the game (physical or digital) your save game will work. The only exception to this is in the case of a new edition of a game, but this occurs rarely outside of games with separate editions in separate global regions.

I used to work for an ISP and there are some things that I can suggest assuming that you did not change anything yourself: - for best connection never use Wifi - do a speedtest from a wired machine that is not your PS4 and check the speed is at a minimum the same as you had before the problem if it is not - ensure that nothing has changed on the router on your end (check the config) and - call your ISP/provider and ask them to check if your subscription is still the same, if this is the case ask them to check the connection it is possible that due to the problems they had that your connection is configured at a lower speed
