In this article, which had a lot of interesting tid bits, one thing that jumped at me was the mention of a new network that Facebook is working on that will be able to transfer 1 gigabyte a second. It goes on to say that this network will be tested this year.
Do those speed specs line up with what we know about our tech? Dots?
