location of cloud providers and data centers can be an important factor in performance, as ideally you want to route and store data through the server that's the closest.Even if your data is "in the cloud," it's still housed somewhere. And as we've written about before, the
In preparation for the launch of its new backup and migration tool, Turnkey Linux has done some work to automate selection of the nearest regional data center.

Below is a map that plots the countries with their associated Amazon region:
And for an interesting comparison, here's a map of worldwide underground cables:
