It's a good thing that Metal Gear Solid 5: The Phantom Pain is still a lot of fun offline, because its first few days have been plagued with slow servers and extended downtime. Now Konami says on its official status page that servers for all the systems should be operating normally - except for PS4.
Konami first disabled some of MGS5's online features, then pulled the servers down to work on them. They've recently started coming back online (I watched the PC servers tick over from "undergoing maintenance" to "operating normally" while writing this) so PS4 likely isn't far behind. Hopefully the online experience will be much improved for players on PC, PS3, Xbox 360, and Xbox One now - but if you find your game starting to lag again, there's always the offline mode.
