Latencies are round-trip times (RTT) between cloud regions or measurement servers located in or near each market, not between specific colocation facilities. Azure figures are monthly P50 (median) round-trip times measured between Azure regions over the 30-day window ending July 30, 2026; city names are mapped to the nearest Azure region (Singapore = Southeast Asia, Kuala Lumpur = Malaysia West, Jakarta = Indonesia Central, Tokyo = Japan East, Seoul = Korea Central, Mumbai = Central India (Pune, ~120 km from Mumbai), Sydney = Australia East, Frankfurt = Germany West Central, London = UK South, Amsterdam = West Europe, Dubai = UAE North, N. Virginia = East US, Dallas = South Central US (San Antonio, TX)). Bangkok figures come from cloudping.co, which measures TCP round-trip latency between AWS regions every 6 hours (Bangkok = ap-southeast-7, opened January 2025); the Bangkok–Dallas pair uses WonderNetwork server-to-server ping averages, as neither AWS nor Azure publishes that route. Actual latency between two specific data centers depends on carrier, route and peering, and can differ by several milliseconds (or more on poorly peered routes) from these cloud-backbone figures, which generally represent near-optimal paths over private fiber.
