For months now the Reach servers have had some pretty bad issues. I, and everyone else, will get sent back to the lobby with the notation “Matchmaking aborted”. Searching is such an incredible pain. Finding full lobbies and getting the search restarted is extremely frustrating, especially when it happens in high number lobby playlists, like Big Team. These server issues have completely killed my will to play Reach, along with many other people I know. Hopefully there’s a way for you guys to fix this or at least acknowledge it. I’ve enjoyed Reach for over 8 years now. Many people still enjoy Reach daily.

Work is being done to repair issues and is scheduled to be completed towards the end of this month: https://www.halowaypoint.com/en-us/forums/cdecc00475c645b9a4d0a156fb542d59/topics/343-response-reach-servers-down/57350f64-2ad9-4189-8c18-79084a3dccb9/posts?page=5#post86
