Thank you! I use Quad9 and have noticed these links stopped working about a week or 2 ago. The problem was I redid my network at that time and kept thinking it was something on my end. I have a firewall with recursive DNS setup and I was able to add my own entry for it, but I’m guessing the IP changes because it only lasted a few days. Now that I know why I’ll see what else I can do since I do enjoy Quad9 otherwise.
