@zacchiro Apparently it was intentional: "The old issues of DWN are still available in their original location on the Debian mailing lists.
www.debian.org/News contains two links to the mailing list archive.
But on the web page, we want to show only the relevant news to our users, which are the recent ones from the last years, but not the very old ones."
Can't say I agree with that thinking. This is how you get link rot.
