Nope, the biggest AWS region is in Virginia (as well as a bunch of others, energy is cheap there). There are also lots of datacenters in Dallas, TX and San Jose

Nope, the biggest AWS region is in Virginia (as well as a bunch of others, energy is cheap there). There are also lots of datacenters in Dallas, TX and San Jose, CA. NYC has a lot of connectivity (throughout the northeast, and transatlantic) but the cost of real estate is so high that it is uneconomical to operate lots of large datacenters there.
The majority of the population in the US is in the eastern half (1/3 in states on the East coast), so you don't actually decrease median latency by putting datacenters in the geographic center: https://commons.wikimedia.org/wiki/File:United_States_population_distribution_2000_census.png https://commons.wikimedia.org/wiki/File:United_States_popula...
- jjeaff 7y agoNope, the mean population center of the contiguous United States is somewhere west of St. Louis. https://en.wikipedia.org/wiki/Mean_center_of_the_United_States_population https://en.wikipedia.org/wiki/Mean_center_of_the_United_Stat... Actually not too far away from the geographic center which is somewhere in Kansas.
- maccam94 7y agoThat doesn't disagree with what I said. The majority is still in the East (the mean is East of the geographic center), and you don't want to optimize for average latency anyway. You'll get the best median latency with two datacenters by putting one on the mid-Atlantic coast (~180M people East of the Mississippi) and one on the mid-Pacific coast (another 50M in Pacific Coast states). That means the latency for ~2/3 of the population is way lower, and the max latency is still about the same as putting them in the center of the country.
