I’ll add this for any future readers who may wonder why not all links work.
The ‘Ubuntu Discourse Service Interruption’ can be read about here at the following post
Two issues of UWN were ‘lost’, and have since been re-posted on this Discourse (in original form; same text goes to a mailing list; though News members also had local copies).
The links that were no longer valid (when published) were left unaltered UNLESS newer links were available. Some links were changed subsequent to re-publication, as our checking for ‘new news’ detected a re-posting which led to link replacing bad link on published issue.
