Tool
Ping / Connectivity Checker
Check if a host or IP is reachable and measure response time. Sends HTTP probes from CyrusX servers — works even when ICMP ping is blocked by firewalls.
Sends HTTP probes from CyrusX servers on the public internet — checks if a host is reachable from outside your network. Not suitable for local/private IPs (routers, LAN devices) — use your device's built-in ping for those.
About
What Does This Ping Tool Check?
This tool sends 4 HTTP probes from CyrusX servers to the target hostname or IP and measures round-trip response time. Unlike traditional ICMP ping, HTTP probes work against web servers behind firewalls that block ICMP — a common configuration in cloud environments and enterprise networks.
Sending probes from an external server (rather than your local machine) answers a different and often more useful question: is this host publicly reachable from the internet? This is the perspective that matters when troubleshooting whether a server is up from external users' view, not just from within your own network.
Results include minimum, maximum, and average response times across 4 probes — smoothing out transient network jitter for a more accurate latency picture.
Use Cases
When to Use a Connectivity Checker
Confirm Public Reachability
Verify a server or API endpoint is accessible from the public internet, not just from within your internal network where routing may differ.
Check ICMP-Blocked Hosts
Many cloud servers block ICMP by default. HTTP probes confirm whether a web server is responding when traditional ping returns 100% packet loss.
Latency Baseline
Establish expected response times for a host before making infrastructure changes. Compare before and after to detect unexpected performance degradation.
Incident Triage
Quickly determine if a reported outage is a total connectivity failure or a higher-layer application issue — is the server reachable but the app crashed?
FAQ
Frequently Asked Questions
Why use an online ping tool instead of the ping command?+
An online tool sends probes from an external server — it tells you whether the host is publicly reachable from the internet, not just from your local network. Useful when debugging connectivity issues for external users.
Why does this work when ICMP ping is blocked?+
This tool sends HTTP requests rather than ICMP echo packets. Most firewalls block ICMP but allow HTTP/HTTPS traffic. HTTP probes confirm web server connectivity even when standard ping shows 100% packet loss.
What does response time tell me?+
Round-trip latency from CyrusX servers to the target. Under 50ms is typical for nearby hosts. Over 300ms suggests geographic distance or congestion. A timeout means the host is down, port is filtered, or the path is blocked.
How many probes does this send?+
4 HTTP probes per check, reporting min, max, and average response times. Multiple probes smooth out transient jitter for a more accurate connectivity picture than a single request.
