Global Ping Test
Measure public-host reachability, round-trip latency, and packet loss from global probe locations.

What does Ping measure?
Each distributed probe sends a bounded set of real ICMP echo requests. The result shows whether replies arrived, minimum, average and maximum round-trip latency, and packet loss.
What does latency mean?
Latency is the round-trip time between a probe and the target. Physical distance, routing, peering, congestion, and the destination network all affect it.
What does packet loss mean?
Packet loss is the percentage of probes without a reply. Network trouble can cause loss, but ICMP filtering and rate limiting can also affect Ping without disrupting application traffic.
Why can Ping fail while a website still works?
A firewall may block ICMP while allowing HTTPS. Compare a failed Ping with the Global HTTP Test or TCP Port Test before concluding that a website is offline.
Ping vs HTTP and Traceroute
HTTP measures the real web application path. Ping measures destination latency. Traceroute identifies responding hops along the network path.
Frequently asked questions
What does Ping measure?
Ping sends bounded ICMP echo requests and measures whether replies arrive, their round-trip latency, and packet loss.
Why can a website work when Ping fails?
A firewall may block ICMP echo requests while still allowing HTTP and HTTPS traffic.
What does latency mean?
Latency is the round-trip time between a probe and the target. Distance, routing, peering, and congestion all affect it.
What does packet loss mean?
Packet loss is the percentage of ICMP probes without a reply. Filtering and rate limiting can cause loss as well as network trouble.
How is Ping different from Traceroute?
Ping measures the destination. Traceroute identifies responding hops along the path and helps locate where latency changes.
