The only way to know from your end if the packet loss is upstream or downstream is modem mode with a PC to allow ICMP for the BQM IP then with Wireshark using the main filter before running host 188.8.131.52 then with it running filter ip.src== 184.108.40.206 then you change the view time display format seconds since previous displayed packet milliseconds
When viewing the ping times they should be 1.000 or 0.999 between each ping if it show a gap longer then 2.000 then its downstream.
Thanks legacy. I have used Wireshark in the past so could theoretically do this test. However, I was rather hoping a VM staff would chip in a say 'Oh yeah - there a problem on this <thing> - scheduled to be fixed by December 2016' But then I am very lazy :-)
