Guide: measure latency to cloud regions
Picking a deploy region from the provider map alone ignores the real path from your team and users. An HTTP ping from your browser shows which datacenter responds fastest on your current network.
The tool fires requests to each region's public endpoints (for example AWS DynamoDB `/ping`). The number is HTTP round-trip time — not ICMP — and is best used to compare regions relative to each other.
Use before provisioning staging, when testing a corporate VPN, or when explaining why São Paulo beats Virginia for a Brazil-based team. Re-run after changing networks or ISPs.
Step by step
- Click Measure latency — Many regions are tested in parallel; the first run may take a few minutes.
- Compare providers — Open AWS, GCP, DigitalOcean and others in the accordion. Unavailable or non-CORS endpoints may fail or look slower.
- Sort by latency — After the run, sort results to quickly see the best options for your location.
- Validate in production — Confirm with real API tests and end users — latency of an empty GET is not a full workload benchmark.
