The path that traffic takes around the internet is not always obvious or logical. Traceroutes are decades old but still useful in diagnosing routing issues.
Supported clients: Whiteboxes, Routers
A traceroute client is used to send UDP probes to each hop in the path between client and destination. Three probes are sent to each hop. The round-trip times, the standard deviation of the round-trip times of the responses from each hop and the packet loss are recorded. The open source traceroute client "mtr" (https://github.com/traviscross/mtr) is used for carrying out the traceroute measurements.
