There was a temporary glitch in the Matrix this morning where comments wouldn't show. On my machine it lasted a few minutes, and the URL above works fine now (though it is flagged).
EDIT: and 35 minutes after I left this comment, it did it again for about 20 seconds. Just a bad HN day, I guess.
I've seen some issues off and on today. Like HN profile pages not rendering anything after the "about" label (even for your own while logged in) as well as submissions/comments pages for a user not rendering anything.
