Measure round-trip time (latency) to any server.
Ping is a network utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the time it takes for messages sent from the originating host to a destination computer that are echoed back to the source.
Low time (e.g. 20ms): Fast connection, good for gaming/VoIP.
High time (e.g. 200ms+): Slow connection, laggy experience.
Timeout: Server is down or blocking ICMP packets.
