Global Ping
Ping a domain or IP from multiple locations across Mainland China, Asia-Pacific, Europe, North America, South America and Oceania.
Measure latency and packet loss from multiple public probes at the same time. Pick the groups you need; each selected node costs one quota point.
FAQ
It sends ping packets to the same target from multiple probes in different regions, so you can compare latency and packet loss around the world on one page.
Probes are grouped into Mainland China, Asia-Pacific, North America, Europe, South America and Oceania. All groups are selected by default; expand a group to see its nodes, and uncheck any group you do not need.
Mainland China is large and cross-border routes vary by region, so the tool pins probes in several cities instead of picking one random Mainland China probe. This gives a more useful view of different regions.
Many networks block or rate-limit ICMP, especially across borders. A 100% loss result does not always mean the target is down. Switch to TCP ping to test a TCP port instead.
It is the registered location of the IP that replied on that probe, not the probe's own location. CDN and anycast addresses can be registered in a different country, so use the probe location to compare network paths.
ICMP ping sends echo requests. TCP ping tries to open a TCP connection to the chosen port; it works when ICMP is blocked and is closer to what a browser does.
Four is a good default. More packets improve the packet-loss estimate but take longer; the number of packets does not change the quota cost.
The public probe network allows 250 rate-limit points per hour per IP, and each probe costs one point. Each selected node costs one point; selecting fewer nodes saves quota. The quota is tied to your own IP because the browser calls the probe network directly.
The measurement is sent directly from your browser to the public probe network. TCPLab does not store the target or results.
