    If the feds ACTUALLY believed he was hacking the plane, why did they wait until it landed to do anything? Shouldn't they have ordered the plane to make an immediate emergency landing before something happened?

    They didn't need to know he was actively hacking the systems to know they needed to take the threat seriously. It was still a credible threat. They waited because, you know, dropping the o2 masks doesn't really mean the airplane is going to crash, and the pilots can actually still fly the plane and everything.

    Had they ordered the plane down immediately while nothing was happening, you'd be complaining how they lept to conclusions and inconvenienced all the passengers and maybe the FBI was the cause of the scare and not the guy who was talking about hacking into the onboard systems.

    When you make jokes about hacking into mission critical systems that could endanger a couple hundred people, you're a fool and need to have a reality check. That's what he's getting.

    He knew he was going to get it, too. According to TFA, they didn't even have to tell him they were on board to visit him. It says the feds walked past his seat and turned around, and he asked "should I get my bags?" In other words, he was getting the response he knew he would get, and that means the response he wanted. An innocent person wouldn't know the feds were there for him. An immediate assumption like he made shows a guilty mind.

    You also know perfectly well that Netflix has offered to place storage services within ISP networks.

    So you think that Netflix can demand that ISPs host their servers instead of paying for the upgrades so Netflix can run their own servers and let the ISPs run their own business? Why does Netflix get to dictate terms like that?

    But even if they weren't, it's none of Comcast's concern as Netflix is already paying for their access and Comcast's customer's are paying for theirs.

    It is patently unfair to expect all of Comcast's customers to pay for upgrades so that Netflix can make a better profit from their high-bandwidth services. Either charge the Netflix customers more for their expanded bandwidth requirements, or get Netflix to pay and then Netflix can pass the costs along.

    Uh, no. Netflix, in case you didn't know, is a company,

    Yes, I think we know that.

    Peering arrangements are not between companies like Netflix and Comcast. Peering arrangements are between ISPs. That's the first point.

    Yes, we know that. What's the point you are trying to make? That Comcast as an ISP cannot ask a heavy outside user of their backbone to help pay for upgrades? Of course they can.

    The second point is that Comcast is not a transit provider. It is a last-mile provider.

    Comcast has its own backbone in addition to the last mile plant. It's two things in one. It has peering agreements with another backbone where Netflix the company gets its internet access. That border is congested because Netflix is sending data through it in large volumes. Netflix is profiting from this traffic, and is paying their ISP -- but not Comcast, who is now expected to upgrade their border connections to make Netflix happy and more profitable. Who pays for that?

    In a traditional peering arrangement the traffic is bidirectional and costs would balance out. With Netflix traffic, that's no longer true. It's not one Comcast customer, and it isn't fair to all the Comcast customers to ask them to pay for someone else's huge use of bandwidth, so they're asking the source of the data. Comcast has a death by a thousand cuts. They can either go after the individual cuts, or find the guy wielding the knife.

    This is not about peering arrangements.

    Yes, when you talk about Netflix and Comcast in the same sentence, it most certainly is about peering. That's where the problem is.

    This is about cable companies.

    Uhh, no. Neither "net neutrality" as a concept nor "net neutrality" as enacted by the FCC ruling is about cable companies. Both are about ISPs. Cable television is a different service. ONE method of internet delivery uses the cable television backbone. There are two other pre-existing wires that go to almost every home: power and telephone. Both are methods of internet delivery, too. And the FCC ruling applies to ISPs no matter what means of delivery is used. If your ISP uses carrier pidgeons, it is covered by the FCC ruling.

    It wasn't going to take long for all of the last-mile networks to try to turn themselves into cable companies.

    What an interesting statement.

    But Suddenlink the ISP knows that its customers can stream Comedy Central from the web, so it is intentionally blocking access to streaming from www.cc.com.

    So go to a different ISP. No, Suddenlink is wrong for doing that, but it has nothing to do with, and is in no way similar to, the Comcast/Netflix issue. Comcast isn't blocking anything.

    Net neutrality may not be perfect in every way.

    Net neutrality as a concept is fine. When you refer to the FCC ruling as "net neutrality" that's where there's a problem. One can be a staunch advocate for net neutrality but still be opposed to the federal regulations now imposed on all ISPs in an attempt to solve the problems of a few.

    But to say that there are no problems out there that need to be addressed

    And I said that when? Never. Maybe smaller words would help. 1) Comcast the cable company has not been granted a monopoly. It is a defacto monopoly through economic causes. 2) Comcast the ISP is not a monopoly of any kind. 3) The FCC ruling will not solve the issues created by large data sources clogging gateway routers. 4) The FCC ruling does allow ISPs to censor content. 5) The FCC ruling does nothing to break up or fix monopoly status for any defacto (or dejure) monopoly currently in existence.

    The part that makes it not cost effective is not the incumbent or the politicians, it is the market itself.

    Comcast has a city wired according to the franchise requirements. Charter decides they want to compete in that market. First, they have to wire it to the same franchise requirements. Then they have to find subscribers. Now, they COULD offer services much better than Comcast and hope they get a sufficient number of subs to cover the fixed costs. Maybe. Or they don't get enough subs and lose money until they shut down. The latter is much more likely when you're splitting a fixed market with another company.

    They HAVE asked Netflix to pay for the capacity upgrade at the border gateways -- capacity that is being used in large part by Netflix and is making Netflix money. Netflix is profiting from a peering agreement that Comcast has to pay for. Seems fair to me that Netflix pays part of the costs of upgrade.

    In fact, I'd say that if Comcast has to increase everyone's bill to pay for capacity upgrades required to handle Netflix traffic, THAT would be charging their customers for Netflix traffic -- even if the customers aren't Netflix customers.
