Hello. Microsoft asked me to contact you as they said your server is stopping me from playing Halo Reach online so I would be most grateful for your assistance Thanks
There seems to be some issues with Reach at the moment, you can follow this thread in the mean time. I believe that 343 are aware of the issues and are currently working to resolve those issues
