As a reminder for folks, on 12/7/20 the NewsDemon Blog noted that article numbering of headers changed (due to their backend move), which was causing general problems. See their blog at:
https://www.newsdemon.com/blog/ for more info. Related to the change I've noticed an awful lot of missing data/articles, even for recent material ("Failed: 430 no such article"). I now have to regularly use my backup block accounts for fills. Until they change to their new backend (late January '21?) I would say their service is no longer generally usable. It's a shame to have such basic problems today, given their stellar history.
