ICMP echo RTT measurement page for Hong Kong (Hong Kong) to New York (USA): 187.8 ms average, 0% loss, with latency stability context.

🇭🇰 Hong Kong (HKG) → 🇺🇸 New York, USA (NYC)

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

During the 2026-08-15T04:03:13Z ICMP echo RTT session from Hong Kong to New York, the average latency was 187.8 ms, with a minimum of 179.48 ms and a maximum of 220.5 ms.

None of the 50 probes were lost, leaving packet loss at 0%. The measured average is 1.48 times the theoretical fiber floor of 127.11 ms for the 12,979.6 km geodesic route, corresponding to about 67.7% fiber efficiency.

Jitter reached 5.66 ms, and the standard deviation was 7.96 ms, indicating moderate dispersion around the mean. This route is ranked 16th among the 19 outbound paths from Hong Kong, and its variation relative to average latency is larger than the 3.08% network median, so zero packet loss coexists with meaningful RTT fluctuation on this East Coast path.

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: HKG → NYC

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 187.8 ± 1.13 ms (SE)

Sample distribution: box = interquartile range (182.4–191.2 ms), median 185.2 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 (127.1 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Hong Kong (22.27832, 114.17469) and New York City (40.71427, -74.00597). It does not disclose either facility address.

Vacuum RTT floor	86.59 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	127.11 ms
Low-latency fiber material floor	126.6 ms
Engineering floor (5% path allowance)	133.48 ms
Research 1.33× mapped-fiber reference	169.05 ms

Published RTT inflation over fiber floor	1.48×

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.
