Netflix Streamed 19,500,000 Terabytes Of Video In The 1st Quarter of 2014

And a lot of that, suprisingly, using FreeBSD instead of Linux or Windows, as can be seen on recent presentation from MeetBSD California: http://www.slideshare.net/iXsystems/scott-long-netflix-updat...

I wonder what the capacity of the internet WAS in the 1st quarter? We hear about what fraction of traffic is this-and-that; but where are we regarding total available bandwidth?
