The BEST command to use to characterize the location and type of failure over the course of several minutes in this scenario would be the "mtr" command, which stands for "My traceroute".
"Mtr" is a tool that combines the functionality of the "traceroute" and "ping" commands. It continuously sends packets to the destination, collecting data on the path the packets take and measuring the response time for each hop. This makes it very useful for diagnosing intermittent connectivity issues.
The "traceroute" command (also known as "tracert" on Windows systems) can also be used to trace the path packets take to a destination, but it only shows the IP addresses of the routers between the source and destination. It does not measure the response time for each hop.
The "ping" command can be used to test connectivity to a destination, but it only sends a single packet and does not provide information about the path the packet takes.
The "netstat" command is used to display network statistics, such as active connections and listening ports. It is not useful for diagnosing connectivity issues.
Therefore, the "mtr" command is the most appropriate command to use in this scenario, as it provides the most comprehensive information about the path packets take to the destination and the response time for each hop.
