Horrible Lag

I am a PS3 player and over the past 2 days I have been encountering horrible lag. I have never had serious issues with lag before. During the duration of lag, my fc mates noticed flickered red light over my head (disconnect symbol).

In addition, I have talked with my ISP, confirmed that I had no late bills or other issues with my network on my end, and checked other programs on my computer, and everything else works fine.

Same here.

Honestly, the PS3 version has lagged for a long time now. I understand it's a cross-system game, which is awesome, but for me on a PS3 on a loading screen for 4 minutes while PC and PS4 players get 20 seconds tops while an S Rank pops, and I miss it because of the loading or get it to it and the lag is so bad, it doesn't load up for about 10 minutes or at 2% health left, it's just not right.
