Just an FYI in case no one has mentioned it already, it appears that after the web server frontend upgrade, the site is not automatically redirecting http -> https connections resulting in insecure connections on a number of browsers (when the short email is typed in without an explicit https:// at the front of "savannah.gnu.org"). I infrequently check the site, and my browser choked on this in standard goose-chase fashion.
This is often considered a misconfiguration, and its fairly normal to redirect to https using a 301 (permanent), or 302 (in temporary cases). If there is a reason for not redirecting in this way, it might be good to post it when soliciting reports of issues following upgrades. Best Regards, N
