How to perform Ping test
========================
In Windows search type cmd and hit enter. It will find Windows Command Prompt. Click on it.
The command prompt window will open.
In the command prompt window, type the following:
ping -t 8.8.8.8
Press enter. 
You should see something like:
Pinging 8.8.8.8 with 32 bytes of data:
Reply from 8.8.8.8: bytes=32 time=14ms TTL=59
Reply from 8.8.8.8: bytes=32 time=15ms TTL=59
Reply from 8.8.8.8: bytes=32 time=17ms TTL=59

This will run endlessly until you stop it. Let it run for several seconds, then press control and c to stop it.
You should see something like this:
Ping statistics for 8.8.8.8:
    Packets: Sent = 3, Received = 3, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 10ms, Maximum = 21ms, Average = 16ms

Note: 8.8.8.8 is used in this example is Google's DNS server. It was chosen because it is a known reliable server available to anyone. You can substitute that address with any reliable server.

What does this all mean? The part that is most meaningful is this:
Lost = 0 (0% loss)
That means there was zero packet loss. Anything greater than zero is problematic. The greater the number is, the worse the condition.
This is also important:
time=14ms
In this example it is telling you that the target server took 14 milliseconds to return a response. The lower the number, the better the response time.
Now try this same test with the server in question. The Deer Isle server address is 66.55.142.50, so the command would be:
ping -t 66.55.142.50
Evaluate the results as described above.
