# São Paulo, Brazil → Berlin, Germany RTT

🇧🇷 **São Paulo, Brazil (GRU)** → 🇩🇪 **Berlin, Germany (BER)**

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

For the 2026-08-16T04:07:28Z measurement round, ICMP echo RTT from São Paulo, Brazil to Berlin, Germany averaged 191.3 ms over 50 samples, with a minimum of 185.86 ms, a maximum of 210.68 ms, and zero packet loss.

The 4.6 ms standard deviation and 3.74 ms jitter show a fairly steady signal, even though the average places the route in the Fair latency tier. It ranks 11th among the 19 outbound routes from São Paulo, putting it on the slower side of the set.

At 1.91 times the fiber-floor estimate of 100.2 ms, the route's 52.4% fiber efficiency reflects the additional overhead beyond the great-circle distance. Its stdev-to-average ratio of 2.40% is well below the 3.28% median for the outbound route set, so this is a comparatively consistent round-trip time despite the higher absolute latency.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/gru-ber.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, São Paulo → Berlin round 2026-08-16T04:07:28Z, CC BY 4.0".
