This is the example that we measure the latency of the content server IP which resolved by the public DNS Server. The concept it simple that we measure the latency.  For the further development, we will auto the measurement process by accessing the domain content header to determine the actual access processing time.The following is the measurement of the top 10 domain name for reference.<br><br><script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.3/Chart.bundle.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.3/Chart.bundle.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.3/Chart.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.3/Chart.min.js"></script><table><tr><td>ISP: 1</td></tr></table>
