We don't know anything about the WS11 traceroute. Time of day? What would repeated WS11 tracerts show? The internet varies from second to second, never mind minute to minute. Same in the VM network.

There are doubtless UK areas where performance differs - but you'd need to prove that WS11 was perfect at all times for your particular case to stand up.

The VM guys are right - in general your pings are poorer outside VM's network. This is where tracert is an inexact art. It's your gaming experience that's going wrong and the data that moves is very different from the tracert data.

I believe your attack needs to be based on a demand that VM lives up to its advertising or that they should stop advertising what they can't deliver and compensate you accordingly.
