Singapore to Los Angeles ping and RTT: 168.9 ms, 2.95 ms jitter, 138.43 ms fiber floor, and 82% efficiency across AS203314. Updated 2026-08-09.

🇸🇬 This page compares the published ping and round-trip time (RTT) from Singapore (SIN) to 🇺🇸 Los Angeles (LAX) with vacuum and optical-fiber physical limits.

As of August 9, 2026, the Singapore → Los Angeles route on Hats Network averages 168.9 ms RTT across a 50-sample daily ICMP echo measurement round (source: GSL), 1.22× the theoretical fiber-floor limit of 138.43 ms.

Among the 19 measured routes departing Singapore, this route ranks 14th fastest by average RTT.

With a stdev-to-average ratio of 2.4%, this route is more stable than the network median of 3.4%. Across the round, per-probe RTT ranged from 165.23 ms to 182.85 ms with a standard deviation of 3.97 ms.

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: SIN → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-09 · avg 168.9 ± 0.56 ms (SE)

Sample distribution: box = interquartile range (166.1–170.4 ms), median 167.5 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 Singapore (1.28967, 103.85007) and Los Angeles (34.05223, -118.24368). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	14,135.8 km
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
Estimated unamplified path loss	2968.5 dB
Transparent optical spans / inline amplifiers	186 / 185
Published RTT inflation over fiber floor	1.22×

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/sin-lax.pings.{csv,json,yaml}.
