Hacker News is upgrading to a new server, as originally reported on Hacker News.  The site should be down for “around 10 minutes” during the switch to the new server at about 6 a.m. EST on Saturday.  According to the post comments, Hacker News gets visits from 200,000 unique i.p.s on weekdays and just under 2 million daily pageviews.  That’s up from 120,000 uniques and 1.3 million pageviews in October 2011.

Surprisingly, Hacker News apparently runs on just one process on one cpu on one server. RTM gives the machine specs: “Old server: two Xeon E5450 chips, 3.0 GHz, 8 cores total, 24 GB RAM.  New server: one Xeon E5-2690 chip, 2.9 GHz, 8 cores total, 32 GB RAM.”
