The devs stream is a house on fire right now. I think the dev has lost connection from the server too, and is now answering and apologizing to the chat, and the chat is getting savage. AngryJoe is out too so he's watching the dev's stream http://www.twitch.tv/angryjoeshow
Because it is not that easy. If there is double more servers then it is today in a month half of them would be empty. Every popular MP game needs from few hours to few days to stabilize servers traffic. It is not best situation but that is how launch of MP games work.
Mine is doing that, too. I couldn't get passed Brooklyn. I guess we started downloading the game late, so it never fully downloaded the game and patch. I have about 5GB left in the download, and a little under an hour of wait time. I don't think I'll get to it tonight, though.
