Hi folks. In case you haven't heard (and there's a good chance you may not have), the Xbox Live service has been undergoing dashboard maintenance and updates today so you could see some network instability across the board.
Those of you playing Forza 2 will see this affecting your ability to access the Auction House. We've been getting lots of email from Forza players asking if their Gamertags have been banned from the online Auction House due to the pop-up message that states you have either been banned or the service is unavailable.
If you know for a fact that you have not violated our Auction House terms of service, then chances are you have not been banned and the reason you can't access the Auction House is due to Xbox Live instability.
Please check back and try to login throughout the day. This problem should resolve itself soon.
Thanks for your patience and understanding.
