Google Cloud latency test
Measure network latency from your location to Google Cloud regions worldwide and find the best region for your workloads. Pings are sent straight from your browser to Cloud Run region endpoints, so results reflect real round-trip time from where you are right now.

Frequently asked questions
What is latency and what constitutes good latency?
Latency, often referred to as ping, is the duration for data to travel from the source to the destination and back. The results of this test represent the median round trip time (RTT) latency to Google Cloud region endpoints, with lower RTT indicating superior performance.
What constitutes good latency? Good latency varies by application type:
- Real-time applications (e.g., gaming, video conferencing): latency below 50 ms is ideal.
- Interactive applications (e.g., web browsing, online trading): latency between 50 ms and 100 ms is usually acceptable.
- Non-interactive applications (e.g., file transfers, backups): latency above 100 ms may be acceptable.
These guidelines may vary depending on specific application needs and user expectations.
How does the Google Cloud Latency Test work?
Your browser sends lightweight HTTPS requests to a Cloud Run endpoint in each selected region. The median latency is calculated by measuring the time between the request and the response.
Does the latency test reflect actual application performance?
Partially. This test is a network-focused indicator, not a full application benchmark.
- ✓ Good for comparing relative latency between Google Cloud regions
- ✓ Useful for region-selection discussions
- ✗ Not a substitute for application-level load or performance testing
Use this test as a signal for initial guidance, not as the sole decision-maker.
Is my speed test result private?
Yes. GCP Speed Test does not require authentication and does not collect personal or corporate identity information. Test results are generated entirely in your browser and are only visible to you. Other users cannot view, discover, or search for your results unless you explicitly share them (e.g., via screenshot). Results are not published, stored, or retained on our servers.
Why might some Google Cloud regions measure high latency?
Distant regions legitimately measure many hundreds of milliseconds — the test never hides a region for being "too slow", it shows the real number. The first request to a cold region also pays a TLS handshake and cold-start cost, so we run a throwaway warm-up ping before recording timed samples.
