Measured ICMP RTT from Taipei, Taiwan to New York, USA: average latency 174.2 ms, jitter, packet loss, and route stability for this trans-Pacific path.

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

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

During the 2026-08-16T04:07:28Z round, ICMP echo requests from Taipei, Taiwan to New York, USA returned an average round-trip time of 174.2 ms, with a minimum of 165.46 ms and a maximum of 214.55 ms. None of the 50 samples were lost, and the jitter figure of 6.73 ms points to a reasonably steady path over a 12,549 km great-circle distance.

At that distance, a theoretical vacuum path would take 83.72 ms and a straight-line fiber path would take 122.89 ms. The measured average runs 1.42 times the fiber floor, or about 70.5% of theoretical fiber efficiency, putting the measured average 51.3 ms above the straight-line fiber minimum.

Compared with the 19 outbound routes measured from Taipei in this round, this path ranked 15th for RTT, meaning 14 routes were faster and 4 were slower. The typical variation from average across those outbound paths was about 3.28%, which helps frame the measured standard deviation of 8.46 ms. With 0% packet loss and 6.73 ms jitter, the route is stable despite an average that lands in the Fair latency tier.

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 2026-08-16T04:07:28Z · avg 174.2 ± 1.20 ms (SE)

Sample distribution: box = interquartile range (168.7–177.3 ms), median 171.7 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.

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.
