ICMP RTT measurements from Amsterdam, Netherlands to Singapore: 157.6 ms average latency, jitter, packet loss, and route efficiency for this fair-latency path.

🇳🇱 Amsterdam, Netherlands (AMS) → 🇸🇬 Singapore (SIN)

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

For the 2026-08-16T04:07:28Z measurement round, ICMP echo RTT from Amsterdam to Singapore averaged 157.6 ms, with observed values ranging from 150.92 ms to 175.59 ms. All 50 probes succeeded, and the 4.44 ms jitter points to a steady fair-latency path.

At 10,503.4 km apart, the two cities have a vacuum light-time floor of 70.07 ms and a fiber floor of 102.86 ms. The average sits 1.53 times above the fiber floor, giving a fiber efficiency of 65.3%; the extra 54.7 ms over the floor is the route's real-world distance penalty.

This Amsterdam outbound route ranks 13th among the 19 routes in the same measurement set. Its standard deviation of 6.2 ms is about 3.9% of the average, slightly above the 3.28% median variability for the set, so the route is stable but not the quietest in the set.

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: AMS → SIN

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 157.6 ± 0.88 ms (SE)

Sample distribution: box = interquartile range (152.8–160.0 ms), median 155.8 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 (102.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Amsterdam (52.37403, 4.88969) and Singapore (1.28967, 103.85007). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	10,503.4 km
Vacuum RTT floor	70.07 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	102.86 ms
Low-latency fiber material floor	102.44 ms
Engineering floor (5% path allowance)	108.01 ms
Research 1.33× mapped-fiber reference	136.8 ms
Estimated unamplified path loss	2205.7 dB
Transparent optical spans / inline amplifiers	138 / 137
Published RTT inflation over fiber floor	1.53×

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.
