Marketplace went down for close on 10 hours yesterday. After a non-committal statement Microsoft has now released some information about the cause of the problem.
Posting on the Windows Team Blog Microsoft said:
The problem was the result of scheduled maintenance being performed on Microsoftâ€™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.
While the explanation does not really tell us in detail what went wrong, at least we know the servers were not down due to hacking, unlike Sonyâ€™s unfortunate situation.
