Live ICMP RTT data from Singapore to Amsterdam, Netherlands: average latency, jitter, packet loss and route efficiency for the 2026-08-15T04:03:13Z round.

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

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

Singapore to Amsterdam recorded a 157.3 ms average ICMP RTT in measurement round 2026-08-15T04:03:13Z, based on 50 samples taken at 100 ms intervals. The minimum was 149.78 ms, the maximum was 176.63 ms, jitter was 5.98 ms, and packet loss was 0%, so the link stayed fully available during the test window.

The observed average sits 1.53 times above the theoretical fiber floor for 10,503 km, giving a fiber efficiency of 65.4%. In practical terms, the route carries a noticeable latency overhead beyond the straight-line cable distance, and the average RTT should be treated as the expected operational latency rather than an ideal-case value.

Among the 19 routes leaving this Singapore origin, the route ranks 11th by average RTT. Its 7.49 ms standard deviation is about 4.8% of the average, higher than the network median of 3.08%, and the 26.85 ms gap between minimum and maximum means traffic engineers should plan for a wider latency envelope than the average alone suggests.

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 2026-08-15T04:03:13Z · avg 157.3 ± 1.06 ms (SE)

Sample distribution: box = interquartile range (151.6–160.0 ms), median 155.2 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.

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

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.
