It's probably just the HN kiss of death. It loaded on firefox/mac for me to the point i got some buttons, but it took so long i just closed the page to reduce the load on it.

I think it might be a FF issue. I had the same issue on FF, but it loaded in Chrome. (also took some time though. 1~min)

EDIT: nevermind, now it also loaded in FF

I suspect it got more traffic than expected. See the same results on Win 11 with Chrome this morning.
