Time Warner Cable Is Not Neutral Toward CDN Traffic (medium.com)

Can anyone propose a plausible reason that a local network would treat CDN traffic differently than non-CDN traffic?

Most content today does come from a CDN. Some content owners and some CDNs (in some locations), will host servers in the local cable company regional centers. Usually google does this. Netflix provides software, to cache its movies, but the local cable company has to install and pay for the HW...Google probably pays for search and maps to be hosted though.

You really need to do a comparison. Maybe after dinner and after midnight run a comparison between your cable connection and your wireless phone connection. Pick a movie and test both. As WFM mentioned, if you can run a traceroute, you can see how your home connection gets to the CDN. In some cases it might terminate at Time Warner, but probably most cases it terminates at the CDN or the content owners origin(Apple for example).

I kinda expect that the after dinner test will suck and the after midnight ones will be much better. You would still need to narrow it down from the cable connection vs the origin (content) server. One way to do that is to compare a video on netflix vs instagram vs youtube. You are looking for throughput and errors/buffers.

I would say complain to the FCC, but...

Coincidentally, the state of New York sued TWC/Spectrum/Charter over this kind of thing. https://ag.ny.gov/press-release/ag-schneiderman-announces-la... I'm guessing these problems don't just exist in one place.
