ICMP round-trip time data from Los Angeles, USA to Singapore: average 168 ms, packet loss 0%, route stability, and network ranking context.

🇺🇸 Los Angeles, USA (LAX) → 🇸🇬 Singapore (SIN)

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

In round 2026-08-15T04:03:13Z, 50 ICMP echo probes from Los Angeles to Singapore returned an average round-trip time of 167.6 ms, with a minimum of 160.34 ms and a maximum of 200.67 ms. No packets were lost, but the 7.08 ms standard deviation and 5.12 ms jitter point to a less steady path over 14,136 km.

Singapore ranks 17th of the 19 outbound routes measured here, placing it near the slower end of the set. Its spread around the average is also wider than the network's median variation figure of 3.08%, so the route combines higher latency with more sample-to-sample fluctuation.

The average sits 1.21x the fiber-only round-trip floor of 138.43 ms, for an 82.6% fiber efficiency. The 40 ms gap between the minimum and maximum captures a meaningful range: even within a single 50-probe run, the route can shift from a clean oceanic baseline to a notably slower result.

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: LAX → SIN

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 167.6 ± 1.00 ms (SE)

Sample distribution: box = interquartile range (163.2–170.7 ms), median 164.8 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 (138.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Los Angeles (34.05223, -118.24368) and Singapore (1.28967, 103.85007). It does not disclose either facility address.

Vacuum RTT floor	94.3 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	138.43 ms
Low-latency fiber material floor	137.87 ms
Engineering floor (5% path allowance)	145.37 ms
Research 1.33× mapped-fiber reference	184.11 ms

Transparent optical spans / inline amplifiers	186 / 185
Published RTT inflation over fiber floor	1.21×

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.

The measurement round behind this page is published as open data under CC BY 4.0 in the Hats Network latency dataset. Per-pair files are available at /opendata/latency/latest/pairs/lax-sin.pings.{csv,json,yaml}.
