TestMy's servers are located world wide, in locations where a large majority of the worlds popular websites are hosted. Despite any distance users in San Francisco can still accurately benchmark their connection here. If you're testing outside the US or EU or Asia you have to understand that the distance will be a factor as well as international Internet routing. If your provider has poor peering or there is a bottleneck along your route then your speed test results will suffer. Greater distances result in more chances for your connection to hit a snag along the route.
