networking - How much network latency is "typical" for east - west coast USA? - Server Fault: the actual math is: 3000 mi / c = 16.1ms
So, light can travel from east coast USA to west coast USA in just over 16ms.
minimum PING response:
- it has to come back too.
- it is traveling over glass fiber, not in a vacuum
- many other components can introduce latency.
a 40 something ms response is the best it's ever going to get.
