In my opinion they are only "somewhat reliable" if they are on your network or very close to your network -we operate one of the speedtest.net sites and for our own eyeball traffic find it to be a "reasonable indicator" of what kind of speeds the customer is getting. To put it a different way, if a customer is getting 20X1 Internet service and the speedtest shows 17 X 0.8 then case closed - if they are getting a speedtest result of 5 X 0.5 then our helpdesk will take a further look - this is really in rough terms...
