What this tool does
Measures real round-trip latency to a host by timing TCP connection setup from our server — the accurate, browser-accessible equivalent of ICMP ping, since neither browsers nor most hosted web servers can send raw ICMP echo packets.
Why TCP instead of ICMP?
Sending a traditional ICMP ping requires raw socket access, which is intentionally restricted on shared and cloud hosting for security reasons. Timing a TCP handshake instead gives you the same real network round-trip measurement — the three-way handshake still has to physically travel to the target and back — without needing elevated privileges.
Reading the results
Min/avg/max show the spread of round-trip times across four attempts; a wide spread often points to congestion or an unstable path rather than a consistently slow one. Packet loss here means a connection attempt timed out completely with no response at all, distinct from a fast "connection refused," which still confirms the host is reachable.
