Diagnosing resolution problems
Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network.
Traceroute outputs the list of traversed routers in simple text format, together with timing information
Traceroute is available on most operating systems.
On Linux:
If the last line of the output does not list 8.8.8.8 as the final hop, or if there are significant timeouts, there may be a network problem preventing you from contacting our servers.
sudo traceroute -n -w 2 -q 2 -m 30 8.8.8.8
