It's no secret. We were happy to answer this last week (https://news.ycombinator.com/item?id=23473932), happy a couple years ago (https://news.ycombinator.com/item?id=16076041), and happy now: we have two boxes (one active, one failover) at M5, a small hosting provider that has good support and better tooling than what we had before. They've served HN well. They seem to be run by engineers, and are engineer-friendly. The founder has been an HN user for 9 years (https://news.ycombinator.com/user?id=mikiem).
I don't remember how Scott found them, but it was through some HN-sympatico source like an obscure technical mailing list. We wanted to switch providers, and it seemed like a good idea to pick one that appealed to people with similar tastes to us and sympathetic with the spirit of HN. It's worked out great so far.
Weirdly, this is at least the third time that you've posted strangely insinuating posts about how/where HN is hosted:

Three starts to look like an idée fixe. I still can't figure out what the insinuation is supposed to be...no, we're not an intelligence front. I really want to put a joke here, but I suppose it would probably only feed whatever this is, so I guess I'd better not.
I just saw this sorry. Reading now.
