the speed of light is 186,000 miles per second. which is infinite most of the time. but not always. take gaming for example, 10 milliseconds is the difference between being the fragg-er and fragg-ee. 10 ms round trip is about 900 miles. so if you are halfway across the country and we're connected to a server in my home town, expect to respawn a lot. latency is a funny thing. perceived latency is non-linear with clocked latency. there's a threshold amount of latency below which your brain won't complain. it just compensates. making latency effectively zero. get a little bit over that threshold and now the brain yowls like a teen with a dead cell phone battery. latency is effectively infinite.
