[GRLUG] OT: latency across MPLS

How far away are the sites?   I see ~20ms getting from GR to Chicago, 40ms to Denver and 65ms to California in just transmission latency.

In a vacuum, signals between computers travel at the speed of light, or 186,000 miles per second. In a fiber-optic cable, they slow down closer to 122,000 miles per second. The loss of speed measures roughly 8.2 microseconds per mile, or 0.82 milliseconds per 100 miles.

Off topic: Just curious if any of you work at a place with an MPLS linking sites in different states, and what's the average latency you're seeing across it.

We get ~30ms (which is horrible for high-speed scanning to a network share across the MPLS).
