View Singapore to Miami USA ICMP round-trip time measurements: average 221.9 ms, jitter, packet loss, and latency analysis for the SIN-MIA route.

🇸🇬 Singapore (SIN) → 🇺🇸 Miami, USA (MIA)

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

Measurement round 2026-08-15T04:03:13Z captured 50 ICMP echo samples from Singapore to Miami, yielding an average round-trip time of 221.9 ms, a minimum of 213.75 ms, and a maximum of 240.71 ms; no packets were lost.

At a geodesic distance of 16,978.7 km, the theoretical vacuum floor is 113.27 ms and the theoretical fiber floor is 166.27 ms, so the average is about 33% above that fiber floor. This route ranked 17th by average latency among the 19 outbound routes measured from the same origin in the round, meaning it was slower than 16 of them.

The standard deviation of 6.42 ms and jitter of 6.07 ms are nearly equal, and the 26.96 ms difference between fastest and slowest replies is modest relative to the 221.9 ms average. Route variability of about 2.9% of the average stayed below the 3.08% median variability for the outbound route set, so the sample was internally consistent despite the long distance.

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 → MIA

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 221.9 ± 0.91 ms (SE)

Sample distribution: box = interquartile range (216.6–224.9 ms), median 220.2 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 (166.3 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Miami (25.77427, -80.19366). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	16,978.7 km
Vacuum RTT floor	113.27 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	166.27 ms
Low-latency fiber material floor	165.6 ms
Engineering floor (5% path allowance)	174.6 ms
Research 1.33× mapped-fiber reference	221.14 ms
Estimated unamplified path loss	3565.5 dB
Transparent optical spans / inline amplifiers	223 / 222
Published RTT inflation over fiber floor	1.33×

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.
