When trying to solve problems with hosting (email and website), it is sometimes useful to be able to test the connection between your computer, and the server providing the service.

The most important details from the answers are the percentage of packets lost. If all (100%) of the packets are lost, then it is a networking problem, rather than fault with the service. Knowing that you can successfully Ping a server will save hours of trying to solve an issue with a particular service, when it is actually a network problem.
