My location: Australia
Why on earth would you open up the servers to outside of AUS? It has a massive effect on latency and gameplay experience! At least make it an option to search locally, globally, or under a set ping limit. I don’t care if I have to wait for a match, it’s better than having a terrible time in-game. Do you want to get more people playing Halo? You’re wrecking the experience with the current matchmaking settings.

server reports can be discussed in the linked thread.
