Netflix has long been judging your ISP's streaming quality, but you've had to dig around blog posts and other less accessible pages to get the low-down on just which networks reign supreme. Its new, dedicated ISP Speed Index page is much more straightforward: stop by and you'll always have a quick glimpse of which internet providers are the most Netflix-friendly across key countries, with more detailed breakdowns for individual nations. Not that there's been an upheaval in the pecking order, at least if you're an American. Google Fiber was once again the clear US speed leader in February, while DSL and Clearwire's WiMAX trailed the pack. The site mostly provides a handy point of reference for ISP shopping, even if it suggests that a cross-country (or cross-planet) move might be in order.
