Live ICMP RTT data for Hong Kong (HKG) to Los Angeles (USA): 147.1 ms average latency, 0% loss, with technical context for this Pacific route.

🇭🇰 Hong Kong (HKG) → 🇺🇸 Los Angeles, USA (LAX)

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

In the 2026-08-15T04:03:13Z round, ICMP echo requests from Hong Kong to Los Angeles returned an average RTT of 147.1 ms, with a minimum of 143.73 ms and a maximum of 161.41 ms.

All 50 probes were answered, so reported packet loss is 0%. That average is 1.29 times the theoretical fiber-path floor of 114.3 ms implied by the 11,671.5 km geodesic distance, putting the route at roughly 77.7% fiber efficiency.

The observed jitter of 2.33 ms and a standard deviation of 3.2 ms show a tight distribution around the mean. The route ranks 9th among 19 outbound paths from Hong Kong, and its stdev-to-average ratio is below the 3.08% network median, making this a relatively stable Pacific route in the sample.

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 → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 147.1 ± 0.45 ms (SE)

Sample distribution: box = interquartile range (145.1–148.3 ms), median 146.3 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 (114.3 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Hong Kong (22.27832, 114.17469) and Los Angeles (34.05223, -118.24368). 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.
