Verizon is blaming Netflix for sending "an unprecedented amount of traffic" and "not taking steps to ensure that there is adequate capacity for their traffic to enter" Verizon's network.

The thing is, Netflix is NOT pushing any of that traffic to Verizon. It is Verizon's customers who are pulling that traffic from NetFlix -- and they are paying Verizon to deliver it!!!

They can claim whatever they want, but when you tunnel Netflix traffic through a VPN so all the ISP see's is encrypted traffic and bandwidth issues disappear, it removes all mystery. I've tried several VPN's to test out my theory, and with each one, as soon as the ISP couldn't inspect traffic, all throttling seem to magically vanish. considering what we're paying for broadband, we should be getting what we pay for wi…

Couldn't it be that your VPN provider has better/less crowded connections to both Verizon and Netflix?

I can see how using a lower grade link to a main source of traffic outside a network can actually shape the traffic and reduce the workload on said network.

If that is not Verizon's doing and if there is some reason why Verizon is not connected to other Netflix's links then I can see it as being out of Verizon hands.

It is more probable, though that the limitations in interconnection between Verizon and Netflix are intentional so as to avoid high utilization of Verizon's network.

Assuming you connected your Verizon IP to a VPN server that resides in a non-Verizon network, that test is insufficient to deduce that the ISP looks at the data. As Verizon is saying, Netflix does not pay enough for the data that they send. They don't need to inspect the data. By connecting your VPN to a non-Verizon network, Verizon sees the Netflix stream coming from that network (not Netflix).

How does Verizon know if Netflix is paying enough for the data they send? They are not Netflix's ISP.

From the article: "Netflix sends out an unprecedented amount of traffic."

YES! Yes they do! But Netflix doesn't send that traffic for fun and giggles, just to swamp your network and clog up the port. They do it because YOUR CUSTOMERS HAVE ASKED THEM TO and you, Verizon, you duplicitous shitbag, have SOLD THAT CAPABILITY to your customers. They have LITERALLY PAID you to successfully receive up to 75Mbps worth of traffic from ANYONE, INCLUDING NETFLIX.

I can't fucking stand this "they send a lot of traffic our way, but we don't send any back!" bullshit. Netflix doesn't PUSH traffic to your customers, your customers PULL traffic FROM Netflix.

I had this same experience with Comcast. See also Level 3's blog post calling Verizon and other ISPs out on this BS: http://blog.level3.com/global-connectivity/observations-inte...

Exactly. Verizon can try to spin this as "Netflix is pushing this traffic on us through inferior intermediate links," but what's really happening is that Verizon's customers are requesting the traffic. The standard response when one of their border links is congested is to work with the peer to upgrade it. Level3 is willing to do so. Verizon would rather try to squeeze money out of Netflix for an unnecessary "direct link". Hopefully people see through this PR.

I tried the same thing a couple of years ago and observed the same, and then switched providers.

Assuming your new provider did not have the problem, which ISP did you switch to?

If only more had that option.

In SF, WebPass (and MonkeyBrains, from what I hear) are great alternative ISPs. Both do point-to-point wireless. My building shares a symmetric 100Mbps connection to WebPass, and I pretty reliably see 30-40Mbps on my wired network. And I pay significantly less than I had previously paid Comcast. (However, I never used the TV component of my Comcast offer, so the cost structure is presumably different for people who do want cable TV.)

I understand that point-to-point wireless is more realistic in an urban environment than in the suburbs or a more rural setting. Do other cities have good alternate ISPs, or are SF residents somewhat unique in their appetite to try alternate providers?

It's so strange, I live in Bolivia and Netflix never buffers for me at all. I have a laughable 200kbps real download speed (1768kbps plan) and I only wait for Netflix to load for about 2 seconds on my PS4 and off I go watching on 480SD quality. I would expect the US to be much much better.

you actually watch below 720p? i'd switch back to downloads for HD before watching something with that resolution.

Honestly though, I can't really tell the huge difference from my couch. I guess my TV isn't big enough to actually notice.

Sure my blurays play at higher framerates and look crisp, but I don't mind watching 480 at all.

Netflix has an open offer to move CDN servers deep into provider networks [1] to avoid peering congestion. This would put most of the Netflix traffic at the bottom right of Verizon's infographic. Why hasn't Verizon accepted this offer?

That's really the key problem here. There is lack of choice in the US and Canada. Everyone loves to drum their chest about capitalism but in this case it isn't working, and ISPs have clearly colluded to divvy up the territories so they aren't directly competing.

The internet has become a public utility just like electricity, water, or the roads. Businesses and private citizens depend on it day to day, and economic growth is hampered by poor performance in this area (e.g. new types of businesses that depend on bandwidth, like a Netflix competitor, cannot exist if the pipes are slow).

In my view the raw cable and fibre should be confiscated from the big three by the government using eminent domain, and then rented out to competing ISPs (including the big three) on even footing. The rent would pay to maintain the cables/fibre and deploy more network, and the ISPs could add a premium before reselling it to end users to cover support costs and maintaining equipment (e.g. routers, edge connections, etc).

Basically make the final mile public property. It would make real competition as smaller ISPs can now compete with large ones, and there isn't regularly problems for these companies (e.g. getting permits to place new cables).
