Just because you’re paying your ISP for a certain level of internet speed doesn’t mean you’re actually receiving that level of internet speed, and Netflix has made it ridiculously easy to figure out if your ISP is screwing you over. There are plenty of websites that can measure your internet speed, but Netflix managed to secure the Fast.com domain, and this website is significantly faster and more clutter-free than alternatives like Speedtest.net. The website starts testing as soon as it loads and presents you with your results within a few seconds, and that’s all it takes to determine whether or not you’re actually getting the internet speed you’re paying for.
