Major Nelson writes on his blog regarding the many Xbox LIVE service issues:
"You may have noticed that the LIVE service has been having a few issues over the past few days. This includes things like signing in, matchmaking and account recovery. Not everyone has had problems, but I know some of you have and I wanted to give you and update. While the service was never completely offline, problems like this are not acceptable. The entire LIVE team has been working day and night to ensure that you can have a great LIVE experience. While we're not done yet, I wanted to let you know that things are getting better each hour and that no one on the team is going anywhere until the job is done".
