Hey @dang, you wouldn't happen to know anything about how Hacker News is hosted, would you? Reading this has piqued my curiosity. If time / your position permits, of course.
From what I remember from previous posts by dang: It's living on a single dedicated server with some hosting company (I think you can look up the IP to figure out which) - at least a while ago the code also was single-core, not sure if that is still the case. (in the past it used cloudflare for caching, but hasn't in a few years)
Last I read it was hosted out of M5 Networks in San Diego. I used to like fairly close to their data center and had considered hosting there at some point, so when I read that Hacker News hosted there it stuck with me.
IIRC it's just stored on someone's Dell Inspiron that they've got laying around in an office. Might be outdated info, but it's really nothing special if memory serves.
