ICMP RTT measurement page for Taipei, Taiwan to Singapore, Singapore: 50 samples, average 44.2 ms round-trip, 0% loss, jitter 1.06 ms.

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

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

In measurement round 2026-08-15T04:03:13Z, 50 ICMP echo samples from Taipei, Taiwan to Singapore, Singapore returned an average round-trip time of 44.2 ms, with a minimum of 42.88 ms and a maximum of 46.44 ms. The standard deviation of 0.96 ms and jitter of 1.06 ms describe a tightly grouped sample, and packet loss was 0%.

The route ranks third among the 19 outbound routes in this measurement set. Its standard-deviation-to-average ratio is about 2.17%, below the 3.08% median for that outbound set, so the stability seen here is better than the midpoint of the measured routes.

For the 3,243.9 km direct-line distance, the fiber-floor estimate is 31.77 ms; the 44.2 ms average is 1.39 times that floor, or about 71.9% fiber-path efficiency. With the 'Excellent' latency tier and no packet loss, most of the measured RTT is explained by physical distance, leaving only a modest overhead component in this sample.

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 2026-08-15T04:03:13Z · avg 44.2 ± 0.14 ms (SE)

Sample distribution: box = interquartile range (43.5–44.8 ms), median 43.9 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}.
