Η Microsoft had an interruption modes that caused various web page content to display issues and the Microsoft Store app to fail to load.
So when they visit www.microsoft.com, subdomain at windows.com or on xbox.com, users were encountering either a broken site layout or an error that said “Your request has been blocked. This can be due to various reasons”, as shown below.
As the Microsoft Store app pulls the data from microsoft.com, the Store page wouldn't open.
At this time all problems seem to have been fixed.
