The problem today seems to be that the game can't create new servers to let more players in. "Some of our Beta servers are currently offline and our team is working with Microsoft to resolve," one of the game's community managers wrote online earlier today. "Stay tuned for updates." It's actually unclear if the problem is that servers are down or if it's that the game can't create new servers.
Microsoft is still working to resolve the connectivity issues to the Beta servers.
