Johannesburg to Taipei ping and RTT: 333 ms, 4.56 ms jitter, 112.87 ms fiber floor, and 33.9% efficiency across AS203314. Updated 2026-08-10.

🇿🇦 This page compares the published ping and round-trip time (RTT) from Johannesburg (JNB) to 🇹🇼 Taipei (TPE) with vacuum and optical-fiber physical limits.

As of August 10, 2026, the Johannesburg → Taipei route on Hats Network averages 333 ms RTT across a 50-sample daily ICMP echo measurement round, 2.95× the theoretical fiber-floor limit of 112.87 ms.

Among the 19 measured routes departing Johannesburg, this route ranks 16th fastest by average RTT.

With a stdev-to-average ratio of 1.9%, this route is more stable than the network median of 3.1%. Across the round, per-probe RTT ranged from 325.9 ms to 355.43 ms with a standard deviation of 6.41 ms.

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: JNB → TPE

50 ICMP echo samples at 100 ms intervals · round 2026-08-10 · avg 333.0 ± 0.91 ms (SE)

Sample distribution: box = interquartile range (328.2–335.0 ms), median 331.3 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 (112.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Johannesburg (-26.20227, 28.04363) and Taipei (25.05306, 121.52639). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	11,525.4 km
Vacuum RTT floor	76.89 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	112.87 ms
Low-latency fiber material floor	112.41 ms
Engineering floor (5% path allowance)	118.52 ms
Research 1.33× mapped-fiber reference	150.11 ms
Estimated unamplified path loss	2420.3 dB
Transparent optical spans / inline amplifiers	152 / 151
Published RTT inflation over fiber floor	2.95×

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