# Paris, France → Hong Kong RTT

🇫🇷 **Paris, France (PAR)** → 🇭🇰 **Hong Kong (HKG)**

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

Measurement round 2026-08-16T04:07:28Z collected 50 ICMP echo samples from Paris to Hong Kong, yielding an average round-trip time of 160.1 ms and a minimum of 155.89 ms. The maximum observed RTT was 182.08 ms, with a standard deviation of 4.45 ms and jitter of 2.89 ms; no packets were lost.

The geodesic distance of 9,647.6 km implies a theoretical fiber-floor RTT near 94.48 ms, so the measured average sits 1.69 times above that floor. The route is running at 59% fiber efficiency, meaning the gap over the straight-line fiber ideal is substantial but the low jitter and zero loss indicate the delay profile is consistent rather than erratic.

Within this round, the Paris-to-Hong Kong route ranked 13th among 19 outbound paths, and its relative variability of about 2.8% sits below the 3.28% median stability ratio for the round. For capacity planning, the route offers a stable delay profile with a clear propagation floor that dominates the observed RTT.

## 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/par-hkg.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Paris → Hong Kong round 2026-08-16T04:07:28Z, CC BY 4.0".
