# Moscow, Russia → Hong Kong RTT

🇷🇺 **Moscow, Russia (MOW)** → 🇭🇰 **Hong Kong (HKG)**

Measurement round: `2026-08-16T04:07:28Z`.

For the 2026-08-16T04:07:28Z ICMP echo round, Moscow to Hong Kong averaged 118.6 ms across 50 samples, with a narrow range from 116.41 ms to 127.8 ms and zero packet loss. A standard deviation of 2.24 ms and jitter of 1.64 ms make this a notably stable path.

The great-circle distance of about 7,154 km implies a fiber floor near 70.1 ms, so the observed mean is 1.69 times that floor and fiber efficiency reaches 59.1 percent. The steady sample distribution confirms the route is behaving close to its physical potential.

This route ranked 9th among 19 Moscow outbound paths, and the median variability across the Moscow outbound set was 3.28 percent of average latency. Its own standard deviation is only about 1.9 percent of the average, so latency is not just low—it is also unusually consistent for this outbound set.

## About This Measurement

Published RTT reflects best-case backbone path behavior measured with ICMP echo probes between PoPs. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. None of these values is an SLA.

The measurement round behind this page is published as open data under **CC BY 4.0** in the [Hats Network latency dataset](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/mow-hkg.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Moscow → Hong Kong round 2026-08-16T04:07:28Z, CC BY 4.0".
