Thank you for the response. I get acceptable results from some servers on pingtest.net
However many of the servers, these are some I tried:
I get a message that says:
Packet Loss Test Error
Couldn't connect to the test server. A firewall could be blocking the connection or the server might be having some issues. Please try again later.
I think rather than issues with those servers or a firewall on my side, it is that what ever is causing my issue is so bad that the test will not even run, depending on how the packets are routed.
I did get one that was a bad, but did return a result
