In a move that surely must have some Internet Service Providers reeling, Netflix has published a blog post that outlines which companies offer the highest-quality connection speed for Netflix streaming. If you’re wondering, the top 3 are: Charter, Comcast, and Cox. Time Warner, Suddenlink, and Cablevision come up from behind, while AT&T and Verizon have some work cut of for them. Other regional providers? Forget about it. It begs the question: do customers of subpar ISPs correlate with customers who keep services like Redbox in high demand? Ken Florance, Director of Content Delivery at Netflix, sheds light on the connectivity findings:
As we continue to stream more and more great movies and TV shows, we find ourselves in the unique position of having insight into the performance of hundreds of millions of long duration, high-definition video streams delivered over the Internet.
The throughput we are able to achieve with these streams can tell us a great deal about the actual capacity our subscribers are able to sustain to their homes. In the charts below, we’re using a time-weighted bitrate metric to represent the effective data throughput our subscribers receive over many of the top ISPs.
Currently, our top HD streams are about 4800 kilobits per second. Clients may switch through a number of bitrates as they ramp up to the highest stream, or shift down from the highest stream if they cannot sustain play at that rate due to throughput constraints. No client would sustain a 4800 stream from start to finish (there would at least be a few smaller streams averaged in for startup) but the higher the sustained average, the greater the throughput the client can achieve, and the greater the image quality over the duration of the play.
