I have no idea whats on the site as my provider blocks it because European sanctions against Russia as this is on of the RussiaToday sites.
In this case, the ISP blocked it because the website is anna's archive [2], which was blocked around a year ago, but they have not made a post about that.
If you put "pcm." in front of the link it will work (for now)
You should probably edit your post, so as not to misinform. But I have to admit this confusion stems from bad decisions at the ISP.
