ICMP round-trip time measurements from Taipei, Taiwan to Singapore, Singapore: latency averages, jitter, packet loss and route performance.

🇹🇼 Taipei, Taiwan (TPE) → 🇸🇬 Singapore (SIN)

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

For round 2026-08-16T04:07:28Z, the Taipei-to-Singapore path returned an average of 44.3 ms across 50 ICMP probes, with a minimum of 42.61 ms and a maximum of 50.6 ms. Packet loss was 0%, with 1.64 ms standard deviation and 1.36 ms jitter.

Over the 3,243.9 km great-circle distance, the observed average is only 1.39 times the theoretical fiber floor of 31.77 ms, yielding 71.7% fiber efficiency. Within the 19 outbound routes from this source, the route ranks third.

The network-wide median standard-deviation-to-average ratio is 3.28%, while this route's ratio is about 3.7%, so consistency is close to the set's typical level despite the strong overall ranking. The standout feature is how close the measured RTT comes to the physical distance floor for an excellent-tier Asia-Pacific route.

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: TPE → SIN

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 44.3 ± 0.23 ms (SE)

Sample distribution: box = interquartile range (43.3–44.5 ms), median 43.7 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 (31.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and Singapore (1.28967, 103.85007). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	3,243.9 km
Vacuum RTT floor	21.64 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	31.77 ms
Low-latency fiber material floor	31.64 ms
Engineering floor (5% path allowance)	33.36 ms
Research 1.33× mapped-fiber reference	42.25 ms
Estimated unamplified path loss	681.2 dB
Transparent optical spans / inline amplifiers	43 / 42
Published RTT inflation over fiber floor	1.39×

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/tpe-sin.pings.{csv,json,yaml}.
