About this test: When a message is sent from our server to your computer it passes through a series of Internet routers. This test uses a technique commonly known as "traceroute" to determine both which routers the messages pass through and how long it takes for our server to send a message to each router and back. This path and timing information is often useful for detailed network diagnostics and debugging—for example, you can see which companies' networks your traffic traverses as your computer interacts with our servers.
