Your Speedtest is (almost) completely irrelevant in the context of ExpatTV. Your Speedtest only measures the speed between you and your ISP, which is usually located geographically very close to you and never has to traverse any external networks – all communication is within the private network of your ISP and therefore is not subject to the slings and arrows of the Internet.
The speed that matters is between you and ExpatTV’s servers in the U.S. Because ExpatTV has to traverse external networks and traffic is carried by multiple providers, ExpatTV traffic is more likely to be negatively impacted by Internet backbone outages, re-routes, and congestion.
The relevant speedtest for ExpatTV is an iPerf3 test run against our servers – we at times run these tests for our clients to show them how their current end-to-end speed between them and ExpatTV is insufficient for satisfactory performance.
