Singapore, Singapore to Miami, USA ICMP echo round-trip time measurement: 221.7 ms average, 8.4 ms deviation, 0% loss, fair tier.

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

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

In the 2026-08-16T04:07:28Z round, ICMP echo RTT from Singapore to Miami averaged 221.7 ms across 50 samples, with a minimum of 212 ms and a maximum of 252.74 ms. Zero packet loss was recorded, and the 6.57 ms jitter figure stayed close to the standard deviation of 8.4 ms, indicating a fairly steady path during the test window.

The raw distance between the two cities is about 16,979 km, which puts a vacuum one-way floor near 113.3 ms and a glass fiber floor near 166.3 ms. This route runs 1.33 times its fiber floor, translating to roughly 75% fiber efficiency, so the observed average is within a plausible range for a long intercontinental crossing.

This path ranked 17th in the 19-route outbound set, making it one of the slower options in the group. Its spread relative to the mean is about 3.8%, slightly above the network median of 3.28%, so while latency is fair, it is not the most consistent route in the outbound set.

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 2026-08-16T04:07:28Z · avg 221.7 ± 1.19 ms (SE)

Sample distribution: box = interquartile range (215.6–224.9 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.

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.
