Would it be reasonable for the order to be the same as that in the download directories (in other words, something like Fedora-$VERSION-$PRODUCT-$ARCH-$IMAGETYPE)? That's the same order as the old pungi images, for example Fedora-20-i386-DVD.iso. - Robatino

If/when this is finalized, RelEng should inform Websites team, so the URLs in the next following iteration of the site templates are written against the naming policy. This was again an issue for F22, because Cloud images all changed location without their knowledge. So our release had 4 hours where any downloads of Cloud images met with a 404/blank page.
