Ping Probe
Send 4 ICMP probes from our server to any target, measuring latency and packet loss.
4 ICMP probes sent from our server
What ping measures
Ping measures the round-trip time (RTT) for ICMP packets between our Singapore server and your target, plus packet loss. It answers "is the target reachable and how far away does it feel" — useful for checking server health and route quality.
Reading the numbers
Latency is dominated by physics: light in fiber travels ~200 km/ms. From Singapore expect ~70 ms to Tokyo, ~150-250 ms to Europe / US. Jitter (variance between probes) matters more than the absolute number for interactive use.
Why ping from our server
Pinging from your own machine tests your local network. Pinging from a fixed datacenter vantage point gives comparable, repeatable numbers — and also tells you how your own server looks from Asia.

Frequently asked questions
The target blocks ICMP — is it down?
Not necessarily. Many servers silently drop ICMP while serving traffic normally. If ping fails, also check the port scanner — a TCP handshake on 443 may still succeed.
Why does latency vary between probes?
Routing changes, congestion and rate limiting all add variance. A spread of a few milliseconds is normal; hundreds of milliseconds of spread indicates congestion or unstable routing.
Can I ping from my own location?
This tool probes from our server. For a test from your own machine to the target, use the speed test — it measures the real route between your browser and our server.
