It depends on how old the post is, how active the forum is, and how you are viewing the forums.
Only a certain number of posts are visible, it looks like somewhere on the order of 6 thousand but that might vary, and highly active forums generally push old posts into the unseeable before-time. If it's important, staff can dredge through older posts to find things.
If you are in Threaded View, past a certain period -- possibly the introduction of threaded view -- you cannot see any posts. If you want to read old posts, you generally Must be in legacy view or they are not even visible.
I don't remember the exact post you're talking about, can you narrow down the date some?
