Some posts are not in first page when I'm logged in

Question

So I was looking to hacker news today when I noticed something. Of all the threads in first page, one of them (beeper mini is back - https://blog.beeper.com/p/beeper-mini-is-back ) disappeared from the main page when I logged in. I tried multiple times, and the result didn't change: as logged out the post is in front page, top 10, as logged in the post is not listed, at least not in the first few pages.I don't remember seeing this pattern before, what would be the idea behind it?

I don't know if this is true for HN or not, but sometimes sites/CDNs cache non-logged-in pages more aggressively than logged-in ones.If it is of any consolation for you, right now I'm both having problems just loading HN and seeing the beeper mini link in the front page (at #6).

My understanding is that HN serves pages from a CDN for non-logged-in views. It is a way of reducing load on the server core that serves HN.
If that's true, then you will see a real-time front page (or a apology for not handling your request) when you are logged in and might see an older cached version of the front page if you are not logged-in.
Of course I might be wrong and there is indeed a scandalous conspiracy of nefarious skullduggery. Good luck.
