ICMP RTT measurements between Paris, France and Singapore, Singapore: average latency, jitter, packet loss and route efficiency for the Southeast Asian path.

🇫🇷 Paris, France (PAR) → 🇸🇬 Singapore (SIN)

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

Measurement round 2026-08-16T04:07:28Z produced a Paris-to-Singapore ICMP RTT average of 150.3 ms from 50 samples, with a minimum of 144.03 ms and a maximum of 164.23 ms. Standard deviation was 4.53 ms, jitter was 4.83 ms, and packet loss remained at 0%.

The straight-line distance of 10,741.6 km corresponds to a theoretical fiber floor of about 105.19 ms, so the observed average is 1.43 times that floor and the path achieves 70% fiber efficiency. This leaves a relatively modest overhead of roughly 45 ms above the ideal fiber path, with the extra delay spread evenly enough to keep jitter below 5 ms.

Among the 19 Paris outbound routes in this round, Singapore ranked 12th, placing it near the middle of the distribution. Its relative variability of about 3.0% is below the 3.28% median stability ratio for the round, so this path is a steadier-than-median member of the current Paris outbound set despite its 150 ms absolute latency.

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: PAR → SIN

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 150.3 ± 0.64 ms (SE)

Sample distribution: box = interquartile range (146.4–152.0 ms), median 149.8 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 (105.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Singapore (1.28967, 103.85007). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	10,741.6 km
Vacuum RTT floor	71.66 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	105.19 ms
Low-latency fiber material floor	104.77 ms
Engineering floor (5% path allowance)	110.46 ms
Research 1.33× mapped-fiber reference	139.9 ms
Estimated unamplified path loss	2255.7 dB
Transparent optical spans / inline amplifiers	141 / 140
Published RTT inflation over fiber floor	1.43×

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.
