Thank you for reaching out.
I understand you wish to know the historical data for the network round-trip latency statistics.
AFAIK currently there is no way to fetch the historical data for the network round-trip latency statistics. It will be helpful if you could create a feedback item for this our feedback portal .
In the documentation you shared above, there is this note below.
So, the month-to-month latency data for last one year cannot be provided. Although as the Azure Documentation is hosted on GitHub, there is a crude way of fetching the latency data based on historical documentation updates of the latency document.
For example, you can get July 2022 Latency Data in this update(scroll below for the inter region latency image)
Hope this helps! Please let me know if you have any additional questions. Thank you!
