ICMP echo RTT from Johannesburg, South Africa to Berlin, Germany: average ping time, packet loss, jitter, and route stability.

🇿🇦 Johannesburg, South Africa (JNB) → 🇩🇪 Berlin, Germany (BER)

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

The Johannesburg–Berlin ICMP echo path averaged 172.1 ms over 50 samples, with a 168.33 ms minimum, a 187.75 ms maximum, and zero packet loss. The 3.76 ms standard deviation and 2.87 ms jitter place this in the fair-latency tier with very tight sample-to-sample behavior.

In the 2026-08-16T04:07:28Z round, the route ranks sixth among 19 outbound routes, and its standard deviation is about 2.18% of the average RTT, comfortably below the 3.28% median ratio for the outbound set. The physical reference is 8,836.6 km of great-circle distance, a 58.95 ms vacuum floor, and an 86.53 ms fiber floor.

The observed average is 1.99 times the fiber floor, which puts the route at 50.3% fiber efficiency. That combination of moderate latency, minimal variability, and no loss gives Berlin-bound traffic a more predictable round-trip profile than many routes in the same 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: JNB → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 172.1 ± 0.53 ms (SE)

Sample distribution: box = interquartile range (169.6–173.3 ms), median 170.8 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 (86.5 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Johannesburg (-26.20227, 28.04363) and Berlin (52.52437, 13.41053). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	8,836.6 km
Vacuum RTT floor	58.95 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	86.53 ms
Low-latency fiber material floor	86.19 ms
Engineering floor (5% path allowance)	90.87 ms
Research 1.33× mapped-fiber reference	115.09 ms
Estimated unamplified path loss	1855.7 dB
Transparent optical spans / inline amplifiers	116 / 115
Published RTT inflation over fiber floor	1.99×

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