SERVER DIAGNOSTIC / ONE PUBLIC TARGET
Ping / Traceroute / MTR
Send bounded real ICMP echo or TTL probes to one public target and inspect measured replies, latency, and hop response loss.

What these measurements tell you
Ping measures real ICMP echo replies and their round-trip times. Traceroute increases the IP TTL or IPv6 hop limit and reads actual ICMP time-exceeded replies. MTR repeats those probes for up to three passes and reports measured reply loss and latency at each TTL.
All modes share a five-second deadline. Ping sends at most three packets, Traceroute eight, and MTR twenty-four; each probe has its own socket. Ping waits up to one second per reply; TTL probes wait up to 150 milliseconds. Reaching the target stops that pass. A missing reply or an eight-hop limit does not prove a host is down.
Routers can filter or deprioritize ICMP. Hop reply loss alone does not establish forwarding loss. Private and blocked intermediate router identities are masked, and the service never connects to a hop address or performs a reverse lookup. Results describe the route from this server.
This tool uses Linux unprivileged ICMP datagram sockets. If the operating system does not allow them, it reports unavailability. It does not substitute TCP for ping, request raw-socket privileges, change system settings, or save probe history.
