PingER uses the ping facility to measure the Round Trip Time (RTT) between about 20 monitoring sites and target hosts in over 160 countries (over 10,00 pairs of monitor-remote target site). Every 30 minutes the monitor sends up to 30 pings at one second intervals to each target until there are 10 responses, and records the data which are daily gathered, archived, analyzed and presented at the archiving site.
