PS3 - Haven't been able to join public game in 3 days.

And it's not just me, my mate a mile or so away is experiencing the same problem.

We can both set up custom games and play them no problem, but joining public playlists just doesn't work, no matter how long you wait.

Seems strange that I cant find anyone on the forums / reddit having the same problem.

What do I do now? Is this a common problem? I haven't played in about 2 months so m completely out of touch with any recent changes and only returned to buy the new maps.

Any help greatly appreciated!
