Ask HN: Is HN running on a bare metal server?

Reading [1] suggests one bare metal server with FreeBSD as OS with a Raid system + a backup server. Found also this [2] suggesting 1 process on Arc language. I actually kind of like the one massive server setup vs a distributed cloud infrastructure to squeeze out maximum performance.
