Frequently asked questions
Where does this region-to-region latency data come from?
The comparison uses Azure network round-trip latency statistics published on Microsoft Learn. Region pairs without a published numeric value are omitted. Published averages are a planning reference; application latency varies with workload, routing, network conditions, and VM configuration.
