[Connectivity] Comcast Throttling Netflix Again?For some time I've noticed that "Super HD" programming rarely displays on my Roku at 1080p and will often drop down into SD. I've run the test video (» www.netflix.com/WiMovie/ ··· 13641790) and it seems to hover around 3000kbps rather than the 5800kbps I typically got just a few months ago. Maybe it's just a temp deal but it's a little concerning. Note that the web interface is limited to 3000kbps (720p) so if you try to test, use your Roku or "smart TV" interface. |

They never did in the first place. Likely not now, either. |

I have watched HD, 3D movies on Netflix on my vizio smart TV and have never had a problem.
I have heard about Comcast throttling Netflix, but have never seen it here.
I have a lot of family and friends who use a Roku without any problems. |

May be more people in your neighborhood have switched to comcast and your node is overloaded. |

Why would Comcast throttles Netflix? To get less customers?
Most likely the realistic answer: everything gets congested during the evening peak times. |

Now that the throttling discussion has been had... OP do you see signs of slowness anywhere else on your network? Are you running wired or wirelessly? Are you using Comcast's DNS servers on your router, or some other one? |

Re: [Connectivity] Comcast Throttling Netflix Again?You may want to check out an old thread » [Speed] Netflix Comcast does not support HD streamingAs for Comcast throttling, I feel you're getting bias opinions here. I absolutely believe they throttle networks. Try using a VPN and see if your speeds increase. » www.itworld.com/article/ ··· own.html |

Yes, they are applying the same throttle they always have, which is none. |

Using a VPN would get your a different path to your content producer (in this example, Netflix.) That path may be less congested than your default path. That's not comcast throttling, thats how networks work. |

Follow the 2nd link I posted above. Then tell me about how Comcast has not and does not throttle.
My son works closely with Verizon and other providers in the field.
The battle for Net neutrality is even evident out in the field. ISPs charge outrageous fees for the use of their poles and no one works on ISP owned poles except for their own employees.
You want use of my poles, Pay me! You want faster speeds to your network. Pay me! That's how business works. |

I agree with maxbrando. My internet speedtests have taken a nosedive after 7PM over the last month. The rest of the day my speeds are fine. |

I think comcast has way oversold the internet capacity with the speed increases.
Consider that on a node with 8 dowstream carriers that everyone shares a single ~343mbs link and on 16 channel node everyone shares a single ~686mbs link.
Even with rather low bandwith applications when everone on the node uses their internet at once that 343 or 686mbs link can get sturated very quickly. |

Comcast does not and did not throttle Netflix (if we did someone or some company could have filed a formal regulatory complaint). It cleared up the moment the deal was done not because of actions we took but because that was the moment Cogent (Netflix's transit supplier) introduced a paid prioritization scheme. » blog.streamingmedia.com/ ··· ane.html |

Netflix has said that only Comcast, Time Warner Cable, AT&T, and Verizon demanded interconnection payments. Other ISPs let Netflix connect for free and, in some cases, host video storage boxes inside their networks to improve performance for customers.
According to M-Lab, performance remained strong on ISPs that weren't involved in the money disputes.
"In New York City, Access ISP Cablevision customers did not experience the same degradation symptoms as Comcast, Time Warner Cable, and Verizon customers when connecting across the Cogent network," M-Lab wrote. » arstechnica.com/informat ··· 0-5mbps/You can play the blame game all you want but statistics show otherwise. |

For whatever reason, they chose to connect directly to Comcast. How does Netflix provide service to end users who subscribe to Comcast because there are no other providers available. That is the current situation in my area. |

said by dolphins:So you're saying Comcast is a poor supplier. No, Cogent was their supplier. said by dolphins:This chart shows how speeds between Cogent and the ISPs dropped off a cliff for several months, recovering only after Netflix began paying the ISPs for direct connections to their networks Prior to that period, Netflix was not using Cogent and service was fine. The introduction of Cogent was the issue, a supplier decision by Netflix. It improved at the time the deal was inked - well before we added direct interconnect capacity sufficient to show that kind of change. As M-Lab themselves noted on their blog, this improvement was solely resulting from a change by Cogent on their network (a prioritization scheme, since they lacked sufficient capacity). See » www.measurementlab.net/b ··· r%202014 and look for the introduction of 0x48 prioritization. |

Re: [Connectivity] Comcast Throttling Netflix Again?OK, I had not seen that before today. It does appear as though Cogent pulled a Chris Christie. My question now is what motivation did they have? How did Cogent benefit from Netflix agreeing to pay Comcast fees? |
