The Great Unracking: Saying goodbye to the servers at our physical datacenter

news.ycombinator.com Ryan Donovan 2026-01-04 00:06:49

Since October 2010, all Stack Exchange sites have run on physical hardware in a datacenter in New York City (well, New Jersey). These have had a warm spot in our history and our hearts. When I first joined the company and worked out of the NYC office, I saw the original server mounted on a wall with a laudatory plaque like a beloved pet. Over the years, we’ve shared glamor shots of our server racks and info about updating them. For almost our entire 16-year existence, the SRE team has managed a
