Measure how fast your connection reaches Cloudflare's global edge network. This tool pings the nearest Cloudflare datacenter several times from your browser, then reports your round-trip latency, jitter, and which datacenter is serving you.
How to use it
- Open the tool — it runs a burst of timed pings automatically.
- Read the average and fastest round-trip times, plus jitter (the spread between samples).
- Press Run test any time to re-measure, for example after switching Wi-Fi or enabling a VPN.
What each metric means
- Average round trip — the mean time for a request to reach the edge and return, across all samples.
- Fastest — your best single round trip, a good read on your connection's floor.
- Jitter — the gap between your fastest and slowest samples. Low jitter means a stable connection.
- Datacenter — the Cloudflare location (IATA code) serving you.
- Connection — the HTTP protocol and TLS version your browser negotiated.
How the grade works
The average is graded roughly: under 40 ms excellent, under 80 ms good, under 150 ms fair, above that poor. This reflects latency to the edge, not to any particular website — a nearby, well-connected datacenter scores well even when a distant origin server is slow.
Frequently asked questions
Why is this higher than a command-line ping? Browser fetch adds a little overhead versus a raw ICMP ping, so treat the numbers as relative comparisons rather than an absolute benchmark.
Do you store my results? No. Every test runs client-side and keeps no record.
Why did some samples fail? Transient network hiccups can drop a sample; the tool simply averages the successful ones.
