Singapore, Singapore to Amsterdam, Netherlands: ICMP round-trip time data with average 155.8 ms, min/max, jitter, packet loss, and fiber efficiency.

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

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

In the 2026-08-16T04:07:28Z ICMP echo round, the Singapore-to-Amsterdam path averaged 155.8 ms with a minimum of 147.48 ms and a maximum of 172.04 ms; none of the 50 samples were lost.

The measured RTT is 1.51 times the 102.86 ms fiber-floor estimate for the 10,503.4 km great-circle distance, so the route converts about 66% of that theoretical minimum into actual progress. This path ranks 12th among the 19 routes measured from Singapore, and its 6.41 ms standard deviation is about 4.1% of the average, above the 3.28% median spread across that set.

Despite the slightly higher variability, the 6.07 ms jitter and zero packet loss point to a stable long-haul route; the largest measured delay was only about 16 ms above the average, so RTT stayed well contained across all 50 samples.

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 → AMS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 155.8 ± 0.91 ms (SE)

Sample distribution: box = interquartile range (150.8–159.2 ms), median 154.2 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 (102.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Amsterdam (52.37403, 4.88969). 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	1.51×

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.
