We have not deployed an X.509 certificate for planet.debian.org. In other words, planet.debian.org was never available via HTTPS.
Currently, it's hosted on machines that host many other websites on the same IP address and you're getting the default HTTPS certificate. Since it is a goal to deploy an X.509 certificate, I'll leave this bug open. -- Luca Filipozzi http://www.crowdrise.com/SupportDebian -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
