Me and a friend have come across this, I've heard a wild variety of speculation over the cause, I only know of one way around, persistence, just keep joining servers, if it takes 10+ minutes to receive data, we tend to give up and find a new server expecting debug forest, we also monitor the amount of disconnects per minute before we commit to loading the server, if people are constantly disconnecting we take that as a sign that newcomers won't be able to get into the server and we find another one, sorry I wasn't able to be of any real assistance, but I'd also like some sort of technical answer to this. (If you were wondering the theories are: The character server is overloaded due to all of the new comers, The game servers are overloaded due to all of the new comers, The server has been running for too long and needs to restart, These are the only ones which I think might have something to do with it, the rest were wild speculation and incorrectly blaming the devs)

You need to have Operation Arrowhead as well as the regular version of the game, the addon folder needs to be in Operation Arrowhead and you need to launch the game as Combined Operations

I'm not sure it is, we've found occasional servers which actually work, only problem is they're perpetually full as people don't leave because they don't need to.
