Where did the Yún Shield Documentation go ???

As someone else mentioned the product disappeared from the product list and it's not even listed as retired. Where is the documentation now?

Thanks!
Alex

It's right there in the "Internet of things" section of the products page but for some reason the link to the documentation only works if you're on the "Europe / Africa" version of the store. If your location is set to "America / Asia / Oceania" then you need to click the location icon on the top bar and change your location.
