Azure network round-trip latency statistics

Article
2024-06-21

Azure continuously monitors the latency (speed) of core areas of its network using internal monitoring tools and measurements.

How are the measurements collected?

The latency measurements are collected from Azure cloud regions worldwide, and continuously measured in 1-minute intervals by network probes. The monthly latency statistics are derived from averaging the collected samples for the month.

Round-trip latency figures

The monthly Percentile P50 round trip times between Azure regions for a 30-day window are shown in the following tabs. The latency is measured in milliseconds (ms).

The current dataset was taken on June 20th, 2024, and it covers the 30-day period ending on June 19th, 2024.

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.

Important

Monthly latency numbers across Azure regions do not change on a regular basis. You can expect an update of these tables every 6 to 9 months. Not all public Azure regions are listed in the following tables. When new regions come online, we will update this document as soon as latency data is available.

You can perform VM-to-VM latency between regions using test Virtual Machines in your Azure subscription.

Latency tables for Americas regions including US, Canada, and Brazil.
