ICMP echo RTT from Singapore to Moscow, Russia: 147.6 ms average, 0% loss, 50 samples from the 2026-08-15T04:03:13Z round.

🇸🇬 Singapore (SIN) → 🇷🇺 Moscow, Russia (MOW)

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

In the 2026-08-15T04:03:13Z round, ICMP echo RTT from Singapore to Moscow averaged 147.6 ms across 50 samples, with a minimum of 144.71 ms and a maximum of 154.68 ms. The standard deviation was just 2.32 ms with 1.95 ms jitter, and no packets were lost.

Although the geodesic distance is shorter at 8,423.2 km, the measured average is 1.79 times the straight-line fiber-floor value, translating to 55.9% fiber efficiency. The route therefore carries more extra latency than an ideal great-circle path, yet the very tight sample spread means that extra latency is stable.

This route was ranked 7th among the 19 outbound routes measured from Singapore in the same round. The set's median standard-deviation-to-average ratio was 3.08%, so this route's 2.32 ms standard deviation is notably tighter than the group norm.

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 → MOW

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 147.6 ± 0.33 ms (SE)

Sample distribution: box = interquartile range (145.9–148.8 ms), median 147.0 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 (82.5 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Moscow (55.75204, 37.61781). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	8,423.2 km
Vacuum RTT floor	56.19 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	82.49 ms
Low-latency fiber material floor	82.15 ms
Engineering floor (5% path allowance)	86.62 ms
Research 1.33× mapped-fiber reference	109.71 ms
Estimated unamplified path loss	1768.9 dB
Transparent optical spans / inline amplifiers	111 / 110
Published RTT inflation over fiber floor	1.79×

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.

The measurement round behind this page is published as open data under CC BY 4.0 in the Hats Network latency dataset. Per-pair files are available at /opendata/latency/latest/pairs/sin-mow.pings.{csv,json,yaml}.
