The Traceroute command displays the list of Internet hops that lie between your local computer and the remote computer. It provides an excellent way to identify connection problems because it is actually showing you the hop that is causing the problems.
Just Traceroute (via Digital Inspiration) takes this a step further by issuing a traceroute command from multiple locations in the world. Different locations, especially when they are from different parts of the world, use different “ways” to reach their target which could give additional information about the cause of the connection problem.
The services is using servers located in the United States, Netherlands, Australia and Singapore to run the traceroute command.

The results can be forwarded to an email address. The very same window offers a way to copy the all four traceroutes to the clipboard directly.
