Re:Network Latencies and Speed of Light

He mentions an overhead of about 11ms in a cross-country network, which may be insignificant in the 35ms overall latency.
But, much of the infrastructure is communicated to regional servers or local CDNs, not cross country. A game server might split loads across east-coast servers and west-coast servers to improve responsiveness. In those cases, it's not unfeasible to see a 2ms-5ms speed-of-light latency. And that's where those 11ms really starts to affect user experience, since now you're looking at latencies that can cut into your 60fps frame rates. (or local video-chat services or even websites)
