LeFantome | on: Microsoft pulls plug on plans for 244-acre data center in Caledonia (2025)
us-east-1 is a region. That means that it is 3 to 6 “availability zones” within a 100 km or so. Each of these availability zones consists of a cluster of data centers. Each cluster is perhaps 3-5 that are a few km from each other. The data centers will have tens of thousands of servers each.

So that is the mental model you should have for “how big is us-east-1”. But also, the data centers are not going to be, individually, anything like 244 acres. Best guess is that individual data centers are between 200,000 and 400,000 square feet. That is 5 to 10 acres.

Do the math above and us-east-1 may be 300 acres of floor space spread over a very large area.

AWS publicly stated I think in 2021 that the larger availability zones in US East 1 consisted of 17-18 datacenters each. It’s likely grown a lot since, and they recently announced AZ7 will be online in Maryland soon, so they must be running out of ability to grow the ones in NoVA.

I can’t find a link now but it was one of the re:Invent talks like Peter DeSantis briefly explaining AZs before he dug into how Amazon optimizes their concrete mixtures to be more environmentally friendly or something…

All things point to that being the biggest region any hyperscaler has in the world, and several gigawatts of power consumption.

James Hamilton also gave a talk in 2021 about AWS having crossed 20 million Nitro cards deployed and 12GW power consumed —
