Microsoft had an outage modes that caused various web page content to display issues and the Microsoft Store app to fail to load.
So when visiting www.microsoft.com, a subdomain on windows.com or xbox.com, the users encountered or damaged layout of the site 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 its data from the microsoft.com website, the σελίδα of the Store did not open.
At this time all problems seem to have been fixed.
