Problems with Service Registration

I play Halo Reach on Xbox 360 and since yesterday (11/05), I can not see my commendations. When I select the service registry option, the following message appears: Failed to download Service Registry. The Halo Reach server is not available. Please try again later.
I’ve already deleted the HD game, cleared the content cache from the console, erased the profile and downloaded all of them again and the problem persists.
Could anyone tell me why this problem is occurring ? Please.

Not just you–it’s everyone. Started yesterday when I got home from work. I pinged 343 on Twitter and came here to post a thread before i saw yours. So no need to delete the game off your drive or clear your cache or anything like that. The issue’s on 343’s end not ours.
