Why do overseas game servers have such high pings?
Why is the latency so high? One reason is because the electrical pulses (or light pulses, in the case of optic fibre) have to travel around the globe and back (15 thousand kilometers down the Southern Cross Cable is approximately 80 milliseconds at the speed of light through fibre optics). Another reason is because there are more intermediatary routing points between you and the destination — each one adding as much as 20 milliseconds delay to the trip. For games that require split-second reaction, such delays are unacceptable. Use a local game server if possible.
