On http://www.webqa.redhat.com/apps/support/documentation, click on the "Red Hat Linux Manuals" link (support/manuals) and will get a 404 error. Actually, looking deeper I see that all of those manual links are broken.
More details. The attempt to get to http://www.webqa.redhat.com/support/manuals results in a 404 error. This page is linked to from http://www.webqa.redhat.com/apps/support/documentation.html
This appears to be resolved. Closing out the bug.
