I go to:
On the left side in the Fedora Documentation frame, I click on PDF in the
pull-down for the Installation Guide. However I don't get the Installation
guide. Instead I get redirected to:
A page with 'Fedora Documentation' in blue appears for a short time. Then
it is replaced with the above URL.
The other options (EPUB, HTML and HTML-SINGLE) all seem to work just fine.
I can get the Release Notes and Security Guide in PDF format just fine.
