Johannesburg, South Africa to Paris, France ICMP round-trip time measurements: 50-sample latency results, packet loss, and network stability from JNB to PAR.

🇿🇦 Johannesburg, South Africa (JNB) → 🇫🇷 Paris, France (PAR)

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

In the 2026-08-16T04:07:28Z ICMP echo measurement round, Johannesburg to Paris averaged 164.4 ms over 50 samples sent at 100 ms intervals, with a minimum of 158.64 ms and a maximum of 177.46 ms. All samples returned, so packet loss was 0%, and the 4.15 ms standard deviation produced 4.24 ms jitter.

The geodesic distance between the two cities is 8,697.3 km, and the theoretical fiber floor is 85.17 ms; the measured average was 1.93 times that floor, an efficiency of 51.8%. This route was 3rd in the set of 19 outbound paths, and its relative variability of about 2.5% of the average remained tighter than the network's median 3.28% standard-deviation-to-average ratio.

Notably, the 18.82 ms spread between minimum and maximum is small for an 8,697 km route, making the 164.4 ms average a reliable diagnostic reference for this pair in the 2026-08-16T04:07:28Z round.

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 → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 164.4 ± 0.59 ms (SE)

Sample distribution: box = interquartile range (161.3–166.3 ms), median 163.7 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 (85.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Johannesburg (-26.20227, 28.04363) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	8,697.3 km
Vacuum RTT floor	58.02 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	85.17 ms
Low-latency fiber material floor	84.83 ms
Engineering floor (5% path allowance)	89.44 ms
Research 1.33× mapped-fiber reference	113.28 ms
Estimated unamplified path loss	1826.4 dB
Transparent optical spans / inline amplifiers	115 / 114
Published RTT inflation over fiber floor	1.93×

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-par.pings.{csv,json,yaml}.
