Two weeks ago, Microsoft Malaysia published a list of 50 templates to help developers creating applications for Windows 8. The links to the SkyDrive account that was hosting the 500 MB file is down and even all the MSDN blog posts that were talking about it have been deleted by Microsoft or their respective authors. I think the reason of this “black out” is the success of the operation, imagine a lot of people downloading the 500 MB file on only one SkyDrive account.
But as you can see on the web site of Microsoft Malaysia, the templates should come back soon. Microsoft will probably host the file on another platform.
