Ping
Send ICMP echo packets from our server to any hostname or IP address. See round-trip time and packet loss.
ICMP may be blocked even when a website or service is healthy.
Enter a host or IP to ping
Packet loss and average latency appear after the check completes.
Ping sends ICMP echo request packets to a host and measures the round-trip time for each one — a direct way to check reachability and latency, independent of the site's content or configuration.
As a rough guide: under 20ms is effectively instant, 20–80ms is normal for cross-country traffic, and consistently above 150ms usually means real distance or a routing problem. Sustained loss above ~5% points to a real issue, and consistency matters too — a steady 60ms beats one that swings between 20ms and 300ms, even if the average looks similar.
Firewalls often block ICMP even when a service is perfectly healthy over HTTP — a failed ping doesn't necessarily mean a site is down. For a fuller picture, pair it with Is My Site Down, Port Checker, or Website Health Check.
| Parameter | What it means |
|---|---|
| time | Round-trip latency, in milliseconds — how long the packet took to get there and back. |
| TTL | Hops remaining. A router decrements it by 1 at every hop, so an unusually low value means the reply crossed more hops than expected. |
| bytes | Size of the echo packet, usually 32 or 64 — rarely significant on its own. |
| loss | Share of packets that never got a reply. 0% is normal; sustained loss above ~5% points to a real problem. |
