Microsoft confirms Windows Phone 7 Marketplace downtime caused by scheduled maintenance

Microsoft has just confirmed what I had been told yesterday. Yesterday’s hours long Windows Phone 7 Marketplace downtime was a result of a scheduled maintenance operation performed earlier in the night:

We regret any inconvenience this disruption caused the impacted customers and our developer community. The problem was the result of scheduled maintenance being performed on Microsoft’s infrastructure during the night. The root cause of this issue has been identified and steps are being taken to help prevent future disruptions to the Marketplace service.”
