I've just found myself at forum.doom9
.net (via a google search), and was a little thrown when I was not logged in, tried to login, not possible,
only then noticed that was not on forum.doom9.org. [so is not exactly a mirror of .org], maybe login has been deliberately disabled since Wonkey post..
Also, Firefox usually shows a little green padlock "verified by Let's Encrypt" icon, whereas .net shows a not verified type icon.
