Ask HN: How do you find an old post that has been hidden?

This morning there was an excellent article from The Atlantic about China's Uyghur treatment through the eyes of a family that escaped to the United States. However, now due to downvoting, flagging, or other hiding, it's no longer on the front page or the next three pages. It had been a front page article. How can I find this submission that is no longer showing up? NOTE: I am not looking for the article (which is called One By One, My Friends Were Sent to the Camps). I am looking for the submission and comment section.
