ICMP RTT measurements from Singapore to Berlin, Germany: average latency, jitter, packet loss and route efficiency for the 2026-08-15T04:03:13Z round.

🇸🇬 Singapore (SIN) → 🇩🇪 Berlin, Germany (BER)

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

Singapore to Berlin averaged 159.2 ms ICMP RTT in round 2026-08-15T04:03:13Z, based on 50 samples with zero packet loss and 4.64 ms jitter. The minimum latency was 153.41 ms and the maximum was 182.06 ms, so the extremes show a wider spread than the jitter figure alone might suggest.

Even though the geodesic distance is 9,925 km, the path runs at 1.64 times the fiber floor and only 61.1% fiber efficiency. The gap between the measured average and the 97.19 ms fiber floor is roughly 62 ms, making this a higher-overhead route relative to its geographic length.

Among the 19 routes leaving this Singapore origin, this route ranks 12th by average RTT. Its 5.95 ms standard deviation is about 3.7% of the average, close to the network median of 3.08%, but the maximum observed at 182.06 ms remains the outlier to watch; with zero packet loss, latency variability rather than availability is the main operational consideration.

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 → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 159.2 ± 0.84 ms (SE)

Sample distribution: box = interquartile range (155.2–160.8 ms), median 157.7 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 (97.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Berlin (52.52437, 13.41053). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,925 km
Vacuum RTT floor	66.21 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	97.19 ms
Low-latency fiber material floor	96.8 ms
Engineering floor (5% path allowance)	102.07 ms
Research 1.33× mapped-fiber reference	129.27 ms
Estimated unamplified path loss	2084.3 dB
Transparent optical spans / inline amplifiers	131 / 130
Published RTT inflation over fiber floor	1.64×

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.
