ICMP round-trip latency from Taipei, Taiwan to New York, USA: measured average, minimum, packet loss, and fiber efficiency for this trans-Pacific route.

🇹🇼 Taipei, Taiwan (TPE) → 🇺🇸 New York, USA (NYC)

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

In the 2026-08-15T04:03:13Z round, the Taipei-to-New York ICMP echo path posted an average round-trip time of 173.6 ms from 50 samples, with a minimum of 168.39 ms and a maximum of 190.79 ms. Packet loss was 0%, and the jitter of 3.75 ms with a standard deviation of 4.84 ms points to a stable long-haul crossing.

The 12,549.1 km geodesic distance puts the theoretical fiber floor at 122.89 ms, so the observed average is 1.41 times the floor and carries a fiber efficiency of 70.8%. This route ranked 15th among the 19 routes measured from Taipei in the same round, so the absolute latency is comparatively high even though the connection is loss-free.

The spread in round-trip times is tight: the 4.84 ms standard deviation is about 2.8% of the average, below the 3.08% reference median for the route set. The practical takeaway is that this path is consistently slow rather than intermittently unstable.

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: TPE → NYC

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 173.6 ± 0.68 ms (SE)

Sample distribution: box = interquartile range (169.9–175.2 ms), median 172.2 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 (122.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and New York City (40.71427, -74.00597). It does not disclose either facility address.

Vacuum RTT floor	83.72 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	122.89 ms
Low-latency fiber material floor	122.4 ms
Engineering floor (5% path allowance)	129.05 ms
Research 1.33× mapped-fiber reference	163.44 ms
Estimated unamplified path loss	2635.3 dB
Transparent optical spans / inline amplifiers	165 / 164
Published RTT inflation over fiber floor	1.41×

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.
