Tens of Thousands of Servers. Wait.

Just one phrase that jumped out of the new missive from Zuck about privacy:

"As a matter of fact, privacy is so deeply embedded in all of the development we do that every day tens of thousands of servers worth of computational resources are consumed checking to make sure that on any webpage we serve, that you have access to see each of the sometimes hundreds or even thousands of individual pieces of information that come together to form a Facebook page." (from Our Commitment to the Facebook Community)

When I tell (non computer) people that it takes hundreds or thousands of servers in hundreds of data centers to run something like Google or Facebook they are surprised.

EvenI am surprised at "tens of thousands of servers worth of computational resources."

Wait , why the nuanced phrasing? What is a server's worth of computational resource? Is that a server or something else? Wait , what's a server anyway? Oh well. Parsing.
