So you can never talk to someone across the country? We are limited by the speed of light, you are never going to get sub 100ms latency across the globe.

>So you can never talk to someone across the country?

You mean across the globe, not country. 100ms ping in domestic call sounds bad.

>you are never going to get sub 100ms latency across the globe.

Latency adds up, bandwidth is calculated by the width of narrowest path, but latency is accumulated.

If you have 100ms ping to local gateway, you still need to add another 100ms for the packet to reach the other side of the globe.

I talk transatlantic and further a lot on t'phone, no real issue
