How is it the only datacenter?
33 Thomas St is basically one huge datacenter, that's why it doesn't have any windows. https://en.wikipedia.org/wiki/33_Thomas_Street
The headline is confusing. It’s Jane Street’s only data center in NYC, not NYC’s only data center.
This was pre-Hurricane Sandy, so before 2012. I'm guessing data centers have grown since then
Jane Street’s only NYC data center. Not the only data center in general.
It's Jane Street's only datacenter. not the only one in NYC. As they explain, they chose to specially locate their datacenter.
