Frankfurt to São Paulo ICMP RTT measurements: average latency, jitter and loss for Germany-to-Brazil network round trips in the 2026-08-16 round.

🇩🇪 Frankfurt, Germany (FRA) → 🇧🇷 São Paulo, Brazil (GRU)

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

During the 2026-08-16T04:07:28Z round, ICMP echo requests from Frankfurt to São Paulo averaged 181.3 ms over 50 samples, with a minimum of 176.28 ms, a maximum of 197.75 ms and zero packet loss. A 3.73 ms standard deviation and 3.34 ms jitter keep the route's variability at about 2.1% of the average, tighter than the 3.28% median for the 19-route set.

Ranked 15th of 19 outbound routes by average RTT, this path is among the slower half of the set, consistent with a great-circle distance of 9,807.7 km. Its average is 1.89 times the theoretical fiber floor of 96.04 ms, giving a fiber efficiency of 53%.

The notable feature is consistency: 50 consecutive probes with no loss and a standard deviation below 4 ms mean the high latency is steady rather than erratic. The Fair latency tier reflects the high absolute RTT, not instability, making the 181.3 ms average a stable reference point for this long-haul 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: FRA → GRU

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 181.3 ± 0.53 ms (SE)

Sample distribution: box = interquartile range (178.8–182.8 ms), median 180.4 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 (96.0 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Frankfurt am Main (50.11552, 8.68417) and São Paulo (-23.54750, -46.63611). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,807.7 km
Vacuum RTT floor	65.43 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	96.04 ms
Low-latency fiber material floor	95.66 ms
Engineering floor (5% path allowance)	100.86 ms
Research 1.33× mapped-fiber reference	127.74 ms
Estimated unamplified path loss	2059.6 dB
Transparent optical spans / inline amplifiers	129 / 128
Published RTT inflation over fiber floor	1.89×

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/fra-gru.pings.{csv,json,yaml}.
