I submitted the link that Julian posted (to his article) on X yesterday. There’s indeed some refresh action in my browser too, but the article opens up.
When it was first submitted the URL was http://0.0.0.0:4000/ .. that's since been magically fixed (by a mod?). I checked http://www.hydromatic.net and the post wasn't visible their either (most recent was Morel Rust release 0.2.0)
Interesting. I just posted the link from this X post [1] without modifying it (and it wasn’t 0.0.0.0…). I think one thing HN does is that when it detects a HTTP redirect, it will start using the referred to URL instead…
