About this tool
What is a looking glass?
A looking glass lets you run network diagnostics from someone else's network. Comparing results from several places shows whether a problem is near you, near the destination, or somewhere in between.
Reading a traceroute
Each line is a router on the path, with the time it took to answer. A * means that router didn't reply, which is common and not an error by itself. Look for where latency jumps or where replies stop for good.
Ping vs traceroute
Ping checks whether a host answers and how fast (round-trip time and packet loss). Traceroute shows the path to it, hop by hop.
