# Taipei, Taiwan → Paris, France RTT

🇹🇼 **Taipei, Taiwan (TPE)** → 🇫🇷 **Paris, France (PAR)**

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

In the 2026-08-16T04:07:28Z test round, ICMP echo requests from Taipei, Taiwan to Paris, France averaged 173.8 ms over 50 samples, with a minimum of 169.08 ms and a maximum of 187.89 ms. Zero packet loss and 3.31 ms jitter accompanied the fair latency tier.

Paris sits on the Northwest European corridor with dense national and pan-European fiber paths. The geodesic distance of about 9,846 km yields a vacuum floor of 65.69 ms and a fiber floor of 96.42 ms; the measured path runs about 1.8 times that fiber floor, or 55.5 percent fiber efficiency.

Against the 19 outbound routes in the same test set, this route ranks 14th, toward the slower side of the round. Its 3.91 ms standard deviation equals a relative spread of about 2.3 percent, below the median variability ratio of 3.28 percent across the same set, meaning the route is predictable even if its average latency is fair.

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