See the route packets take from our server to a host: which networks they cross and where latency grows.
It shows every router (hop) on the way to a host, revealing where loss or latency appears — your side, your ISP, or the server.
That hop doesn't answer diagnostic packets. If later hops respond, it's fine.
Windows: cmd → tracert example.com. macOS/Linux: traceroute example.com (or mtr for continuous stats).
