Check Ping: Global ICMP Test from 50+ Locations

Enter a domain or IP address above to begin the global ping test.

Global ICMP Ping & Network Latency Test

Ping sends ICMP echo requests to a target and measures how long each packet takes to return. This tool runs that test simultaneously from over 50 nodes across different countries, ISPs, and data centers. The result is a quick read on whether your server is reachable globally and how response times vary by region — without installing anything or logging in anywhere.

Latency and Packet Loss

Latency is the round-trip time in milliseconds. What matters is not just the number but how it varies across locations — a server answering in 8ms from Germany and 270ms from Australia is completely normal. The same server timing out in Singapore while responding fine elsewhere is a problem specific to that path. Packet loss above 1–2% on a clean internet connection is worth investigating further.

Anycast & BGP Routing

CDNs like Cloudflare, Fastly, and AWS announce the same IP from multiple locations simultaneously using Anycast. A ping from Frankfurt to an Anycast address should hit a nearby edge node and return in single-digit milliseconds. If Singapore returns 150ms to the same IP, traffic is likely routing to the wrong region — usually a BGP configuration issue on the CDN or a transit provider not accepting the announcement locally.

Live Monitoring Mode

A standard ping sends a few packets and stops. Live mode runs for 60 seconds continuously and plots each response on a chart as it arrives. This is the right approach when you suspect intermittent drops — a one-off test might catch a clean window, while a 60-second stream shows the loss spikes that are actually hitting users. It is also useful during incident response to watch whether a fix is taking effect in real time.
