Microsoft explains when Halo: The Master Chief Collection uses a dedicated server or a peer connection

Microsoft just launched Halo: The Master Chief Collection for the Xbox One, and the shooter is facing a number of issues that are preventing players from getting the full online experience. But that’s not because Master Chief lacks dedicated servers.

Like Call of Duty: Advanced Warfare, the Halo bundle uses a hybrid system that features both dedicated servers and peer-to-peer connections. It always tries to host its public matches on the best connection (which is almost always the dedicated servers), but that’s not always possible.
