We’re not sure if this is just a temporary error or something more nefarious but Google appears to have changed something whereby Windows Phone users are now blocked when trying to access maps.google.com.
Granted, it’s not clear why you would want to use Google’s less-than-awesome mapping service through a browser, but humor us for a second. The move appears to be a continued approach to lockout all Google services from those who adopted Windows Phones. Or it’s just poor service.
We were able to verify on our Windows Phones that when going to maps.google.com we are redirected to www.google.com/m for mobile, regardless of IE10’s settings i.e. Desktop mode. Reports suggest that maps.google.co.uk still works for some folks but for us that too redirects, making this an in-motion change that is evidently occurring worldwide.
