Rage quit no, but maybe got disconnected once or twice due to poor connection (presumably not mine)? I still am able to connect to others, it's just that the frequency is tremendously down. I use to be able to get a game going immediately, now it takes a few minutes (or longer).
When I do get connected, I'm typically connected to the same individuals over and over again (even if they keep leaving and reconnecting). That's out the ordinary for me as well.
