Those attempting to download Microsoft Surface Pro firmware and drivers today are finding it a bit tough to do, considering the original download page is either missing or has been removed.
Original download page: http://www.microsoft.com/en-us/download/details.aspx?id=38826
For now, some have suggested using the Google cached page to obtain the downloads if you need them quickly: Google Cache of Surface Pro firmware and driver packs. This still works.
Interesting enough, the download reference is still showing up in a search of Microsoft's Download site…
But, clicking on the supplied link results in the following…
I have a note into my contacts at Microsoft to verify and will update you when I get word back.
UPDATE 1: Apparently, there's more than just the Surface Pro downloads being impacted. I've confirmed with my sources that the Microsoft Download site itself is experiencing problems and is currently being worked on.
