I appear not to have made my sarcasm obvious enough. :P I was amused by the thought of CIA agents being told that they need a VPN installed and so downloading the first result on Google.
My hypothesis: people who are already using VPN egress traffic in IAD (which has the largest AWS region), thus the results based on IP address is skewed by people who actually live in other countries or maybe even continents.
Wouldn't int'l users choose the location closest to them? If you're in China for instance you're probably going to be using SIN or TPE. Besides, most VPN providers avoid Amazon and use colo providers that give much better deals on bandwidth.
This was my first thought, too. But these aren't data for VPN usage. Just searches. Why would Langley have a bunch of people Googling VPNs in March?
