[SIGCIS-Members] Internet traffic in northern Virginia

We sometimes forget that a large number of messages (as compared to volume of data) is generated for the DNS rather than for directly transporting dat and that NOVA has a substantial part of the DNS infrastructure.  Still, I have a hard time turning that observation into 70% of anything. 

On a related point, the largest chapter of the IEEE-CS is the Nova chapter but that is a little artificial as the Bag Area is divided into three chapters.

There are approaching a billion internet users in China alone, close to a third of the world’s total, and I doubt their traffic is being routed through Virginia. So does Loudoun Country handle 100% of the non-Chinese traffic? Or are some internet users in the DC area, most obviously the NSA, using enough bandwidth to each outweigh hundreds of millions of Chinese smartphone users?

It is now a diverse, IT- and Defense-oriented exurb of DC. The article mentions in passing that “70% of the world’s Internet Traffic passes through” Loudoun County data centers.
