if you noticed, it checks for packet loss from the client side all the way up to US East/West coast. Still is useful as you can see the UK side of things which may affect you on the VM network. My results as you can see above are very stable but seeing i have 2% packet loss in my area would explain slightly higher than usual pings times and sub 20Mb speeds recently.
As for Noggo suggestion, to test individual game serves, ping plotter is the better option to isolate whether it may be the game server or your equipment that may have the problem.
