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

Measurement round: 2026-08-15T04:03:13Z.

Average RTT on the Paris-to-Taipei ICMP echo route was 172.5 ms in the 2026-08-15T04:03:13Z round, from 50 samples at 100 ms intervals. The minimum was 167.65 ms, the maximum was 187.88 ms, and packet loss was 0%; the 4.64 ms standard deviation and 3.81 ms jitter make this a tightly behaved route.

This route ranked 14th of the 19 outbound routes measured from the same origin, placing it in the slower portion of that set. Its stability is better than the typical route, however: the standard deviation is about 2.7% of the average RTT, below the 3.08% median standard-deviation-to-average ratio for the set.

Against a geodesic separation of 9,846.2 km, the theoretical fiber-floor RTT is 96.42 ms, so the observed average is 1.79 times that floor, for 55.9% fiber efficiency. The best sample, 167.65 ms, is still 74% above the fiber floor, indicating the practical path carries considerably more delay than the direct-line reference.

Ping Measurement Series

The chart below renders the 50-sample ICMP echo measurement round for this route; an accessible table of every sample is included with the chart.

Ping series: PAR → TPE

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 172.5 ± 0.66 ms (SE)

Sample distribution: box = interquartile range (169.5–174.2 ms), median 171.3 ms · whiskers = min–max · diamond = round average · each dot is one measured sample.

How to read this chart

The shaded band spans the measured minimum to maximum RTT of all samples collected up to that point, and the thin line traces the running average. The final position therefore matches the round statistics exactly — the band only widens when a new extreme sample arrives.

The dashed line is the round average, and the shaded band at the bottom is the theoretical fiber-optic floor (96.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Taipei (25.05306, 121.52639). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,846.2 km
Vacuum RTT floor	65.69 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	96.42 ms
Low-latency fiber material floor	96.03 ms
Engineering floor (5% path allowance)	101.26 ms
Research 1.33× mapped-fiber reference	128.24 ms
Estimated unamplified path loss	2067.7 dB
Transparent optical spans / inline amplifiers	130 / 129
Published RTT inflation over fiber floor	1.79×

Attenuation is used to estimate the number of 80 km optical spans; it does not directly slow light. See the full theoretical fiber latency, GeoNames, attenuation, and amplifier methodology.

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.
