The latency statistics presented in this article are based on the 50th percentile (P50) of these measurements, which represents the median round-trip time. This means that half of the measured round-trip times are below this value, providing a reliable indicator of typical network performance.

For readability, each table is split into tabs for groups of Azure regions. The tabs are organized by regions, and then by source region in the first column of each table. For example, the *East US* tab also shows the latency from all source regions to the two *East US* regions: *East US* and *East US 2*.
