# Berlin, Germany → São Paulo, Brazil RTT

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

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

During round 2026-08-16T04:07:28Z, 50 ICMP echo samples from Berlin, Germany to São Paulo, Brazil averaged 186.5 ms, with a minimum of 179.2 ms, a maximum of 206.69 ms, and zero packet loss. Jitter of 5.27 ms and a standard deviation of 6.78 ms keep the path in the fair latency tier.

At 1.86 times the 100.2 ms fiber-floor estimate for the 10,232 km separation, the measured average translates to 53.7% fiber efficiency. The spread is about 3.6% of the average, which sits close to the 3.28% median variability seen across the 19 routes in this round.

Ranked 16th of those 19, the route's absolute RTT is the main constraint; its loss-free, moderately jittered profile suggests a stable path whose cost is distance rather than erratic behavior.

## 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/ber-gru.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Berlin → São Paulo round 2026-08-16T04:07:28Z, CC BY 4.0".
