It seems the Ubisoft news website is a bit buggy, or theres an issue with its cached pages. If you go to the main news page[0], its not there. However, if you click "Latest", it brings to to the same URL, but with the Blender article on top. Clicking that still brings you to the notfound page you linked.

Edit: It's now there on the news home page without having to click "Latest", but it still 404's.
