NGlobal Network Latency Averages
  The below listed measurements of latency on AT&T's Global IP Network represent the average interval of time it took during the applicable calendar month for test packets of data to travel between selected pairs of the AT&T Network Nodes within the regions specified below. Over 2800 measurements are taken for each city pair over an entire month to derive the reported monthly average. AT&T believes this type of measurement more accurately reflects customer's real life experience, rather than measuring ICMP traffic such as pings.

For more information about how these statistics are compiled and displayed, check out our methodology.

The table below provides examples of round-trip latency performance data on selected city-pairs within AT&T.s Global IP Network:
