# Paris, France → Taipei, Taiwan RTT

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

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

During the 2026-08-16T04:07:28Z round, ICMP echo requests from Paris to Taipei returned an average round-trip time of 171.9 ms across 50 samples. The fastest reply was 163.74 ms, the slowest 192.89 ms, and with a standard deviation of 7.09 ms and jitter of 5.24 ms the path remained consistent with zero loss.

The observed RTT is 1.78 times the fiber-floor estimate of 96.42 ms for the 9,846.2 km great-circle distance, corresponding to a fiber efficiency of 56.1%. The excess over the floor represents cable routing and switching overhead, and the low jitter plus complete reply set suggest it is not driven by congestion.

On the Paris outbound set of 19 routes, Taipei ranks 14th and falls on the slower side of the group. The median standard-deviation-to-average ratio for those routes is 3.28%; at 4.12% of its own average, this route's variability is only slightly above that norm, making the measured 171.9 ms a stable result for the route.

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