Pro move: type dmarc:yourdomain.com or blacklist:1.2.3.4 straight into the box — it switches tools for you.
About this tool. Classic ICMP ping can't be sent from a serverless edge, so we measure the next best thing honestly: full HTTPS round-trip time to the host, three times in a row. It answers the same question — is the host up, and how far away does it feel.
How to read your ping & latency test results
We measure round-trip time from our edge to the host you enter. Lower is faster.
This reflects the path from our network, not from your own location, so treat it as a relative signal.
Common problems and how to fix them
Latency is unexpectedly high
High round-trip time can mean a distant server, network congestion, or an overloaded host. Compare against a known-fast host to calibrate.
Common questions.What does the latency test measure?
The round-trip time from our edge network to the host you specify.
Is this the same as ping from my computer?
Similar idea, but measured from our servers, so absolute numbers differ from a ping on your own machine.
