Complain about Comcast=Have your Reputation Scrutinized

I'll keep this short. Certainly the Comcast forum has had its share of "hurt letters" by users who switch to DSL or FIOS and want to give a final F-U. I liked Comcast -- I never thought I'd be one of 'em.

I liked Comcast HSI, because it generally worked very well and it was very open and useful for net junkies like me. I thought it was surprising when the company was caught blocking P2P uploads, but I kept the faith and figured if I hung on long enough that they'd change their ways. I've had my service since it was TCI, then AT&T Broadband, and now Comcast.

Clearly, it's now going to take an act of the FCC to change their ways, because Philadelphia has drawn a line in the Sand(vine). That would have been okay, too, because once Sandvine was gone, things could return back to normal, right?

No, because Comcast decided to personally attack me several days ago, in a public filing in the FCC case.

The last time I looked, I was a paying customer in good standing. Yes, I had a grievance but I tried to remain factual and objective and positive throughout, working within the system and through all levels of corporate and government channels and for what? To have my qualifications questioned by a bunch of bumbling bureaucrats at "One Comcast Center?"

What the hell does the contents of my blog -- which neither supports nor refutes the facts of this case -- have to do with anything? Answer -- nothing.

When the AP and EFF have independently confirmed my findings, what does digging into my resume have to do with anything whatsoever? Answer -- nothing.

But now it's clear to me that exercising my rights as a consumer and working within the system isn't enough for this company -- they want to tarnish my reputation as well. How, then, can I trust you not to monitor my transmissions and use the contents of my private transmissions between my trusted advisors and friends to win your case?

Answer: I can't.

Lack of competition means that leaving Comcast HSI behind is quite a big step down for me. But I've had DSL for a few months now, and it's definitely got its own problems -- but one of them isn't a "dirty tricks" campaign against a customer with a service problem.

Wow, that's some seriously high powered stuff they've got there in that letter. I think that, if anything, the level of exposure they've given into the underpinnings of both sandvine as well as the mentality of the whole thing is telling.

They contradict themselves many times in this, saying that they strive to provide

I found this particularly unnerving:

We considered whether some form of metered usage could adequately address the problem. Metered usage would allow us to ensure that we are appropriately distributing the costs of the network usage to those who use the network most. However, metered usage has not been widely accepted in the marketplace, and, in any event, doesn’t directly address the issue of congestion in the network.
I also find that this is a complete misunderstanding of what the reset packets, and moreover the whole reset-packet based shaping architecture is like:
This action is nothing more than the system saying that it cannot, at that moment, process additional high-resource demands without becoming overwhelmed, just as a traffic light regulates the entry of additional vehicles onto a freeway during rush hour. One would not claim that the car is “blocked” or “prevented” from entering; rather, it is briefly delayed, then permitted onto the freeway in its turn while all other traffic is kept moving as expeditiously as possible.
Not only is the use of an analogy such as this overly simplified, it's fundamentally wrong. Sending a reset packet is more along the lines of allowing the traffic to proceed through the intersection at a green light, yet suddenly alerting the driver that they've ran a red light and need to reverse back across the intersection. It's flawed because the connections are actively being rejected.

Comcast’s network management practices are not discriminatory and are entirely agnostic as to the content being transmitted, where it is being sent from or to, or the identity of the sender or receiver.
This is just an outright lie, considering that they themselves admit to targeting specific protocols (BT/P2P) and the upstream path in particular for sandvine throttling. What they've said here is that they employ a completely protocol-agnostic QoS policy (essentially the pure definition of Net Neutrality), yet in the course of the document, shoot it all to pieces. This is a complete fabrication I hope the FCC doesn't let be pulled over itself.

Comcast does not block peer-to-peer (“P2P”) protocols.
This is entirely semantics. It's clear that all that Comcast has to defend itself is its unending stream of semantic, lawyer-esque semantics about what constitutes "blocking."

I think your reply was extremely professional, to the point, and exacting.

The part at the end about the blatant mudslinging going on from Comcast's side is very well done.

I find it ironic that they see fit to make claims that you don't understand the network, when it is the blatant level of secrecy they approach these kinds of supposed "end-user-transparent" network changes which prevents you from knowing about it in the first place.

Honestly, all this stuff is making me wonder whether ISPs shouldn't be required by the FCC to deploy, maintain, and update some basic standardized network topology map for their customers. This way, there's no guessing about if/where/to-what the NebuAD boxes are connected to, and where Sandvine is running from. Some sort of transparency may well benefit the consumer, as well as the FCC in dealing with these kinds of issues.

The problem with the whole thing is that, for some reason, the "last mile" has decided it can arbitrarily violate the most sacrosanct of TCP/IP routing rules; only devices at the "edge" of the network actually change or modify data. The stipulation is that everything in-between doesn't do SPI, doesn't deliver user-tailored ADs, doesn't track browsing metrics. All that this news does is tell me that the edge to edge stipulation of network routing is basically dead. If ISPs can do it, what's stopping Level3? What's stopping all the hops between you and me from inserting their two cents, sending reset packets, or throttling?

It's funny you should pick that. They've also admitted in a previous filing HERE, that Sandvine doesn't directly address the issue of congestion in the network, either.
Specifically, Comcast’s current P2P management is triggered when the number of P2P uploads in a given area for a particular P2P protocol reaches a certain, pre-determined level, regardless of the level of overall network traffic at that time, and regardless of the time of day when the applicable P2P protocol threshold is reached.
That's right!! -- Sandvine doesn't use congestion as a factor. It simply counts connections that it thinks are uploading and cuts off anything above that count, even if there is bandwidth available! It's what I had been saying all along that the level of interference didn't go up and down following probable congestion patterns (despite my obvious lack of qualifications ), but was the same level 24/7.

So, here's their defense? Given the choice of preventing congestion by ...
A. publicly organizing their business model with "metered usage" which was not widely accepted in the marketplace nor directly addressing congestion, or
B. secretly blocking uploads using packet forgery methods and also not widely accepted in the marketplace and ALSO not directly addressing congestion
... Comcast chose "B"? Not that I would want metered usage, but at least it's honest.

Our reply to that disclosure is HERE and most of the geek stuff starts on page 8.

In reference to the bit about network upgrades.

Doesn't changing upstream modulation profiles count as an upgrade? Going from 16QAM to 64QAM for example gives you a nice bit of extra upstream bandwidth. Or even going from a 3.2mhz 16QAM carrier to a 6.4mhz 16QAM carrier for that matter. Comcast may not have implemented DOCSIS 2.0 everywhere but it seems to be implementing it on a as-needed basis. Which is probably what prompted them to give everyone a boost in upload speed in the first place.

And to your point about the placement of sandvine servers, I think you should have visited Comcast so you could re-evaluate that point.

It's not surprising that this whole debate has generated into an attack on your character sadly. It is a legal move to discredit one of Freepress' star witnesses so to speak.

Yes, if and where that happened. But Comcast has been rather vocal about where it does network improvements and it hasn't been saying much about doing DOCSIS 2 upgrades. I think it's been holding out for DOCSIS 3. (Wouldn't you if you were them?) It has DOCSIS 2 in the former Adelphia areas and anywhere else it may have inherited the equipment from a network purchase.

It's possible that they've been quietly upgrading the DOCSIS 1.1 network to DOCSIS 2.0 in order to change the upstream modulation. But their silence on the matter, pressure by investors to keep capital costs down, and the advent of DOCSIS 3 indicate that, by and large, the DOCSIS 1.1 areas will remain DOCSIS 1.1 until DOCSIS 3 rolls around.

Can you give some examples?

Even if they told me point blank (which they have, in filings), I'd still have to point back at the data which indicated that it was at the Access Router. The test result is the result. Why would the TTLs be exactly right for the Access Router and be all wrong for the CMTS? We are talking about TTLs on forged packets, though -- but that they would choose exactly the wrong TTL is somewhat of an unlikely coincidence.

I also wonder if things changed. I first detected this in March of 2007 and my tests that showed TTL were in August '07 (I think). Could Comcast have bought more Sandvine and/or reconfigured between then and now?

But as I said in the filing, it's ultimately a moot point since Sandvine doesn't look at congestion so where to place the box in the network has no effective difference (and it is more efficient to put it at the Access Router since Congestion is not even looked at before blocking uploads).

Although I see where you're coming from, that's ultimately no excuse and no way to treat a very-long-term customer. We should be debating with data being shared openly, not personal attacks to divert attention from the facts.

DOCSIS 3.0 does not fix the problem of using old modulation schemes on the upstream. It introduces channel bonding on both the up and downstream but what would you rather channel bond, QPSK channels or 64QAM channels? Getting the plant to DOCSIS 2.0 is an important step in the grand scheme of things. To get to a 50/10 speedtier you basically need to have DOCSIS 2.0 upstream modulations deployed. Upstream channel bonding will not be available for awhile yet.

As to your question about which areas are seeing DOCSIS 2.0, well we all know Minnesota has DOCSIS 2.0 deployed. I believe quite a few markets have deployed 6.4mhz channels but that is hard to glean from one's cable modem.

As you mentioned in your rebuttal letter virtual node splits can be implemented with relative ease and with little impact to the end subscriber. With the way most CMTS line cards are designed there usually ends up being quite a few extra Upstream ports available for use. Using multiple returns to a node is another way to effectively "uprade" capacity. As is changing modulation schemes. I think Freepress' generalization of the upgrades as window dressing is based merely on opinion and not fact. We know the options discussed above are available to Comcast and would cost them relatively nothing to implement. My point is that it is fine to remain skeptical with Comcast but to note that upgrades are possible without costly upgrades to "the core network."

It is clear at this point that the only way for Comcast to deliver unhindered service that they oversold to the customers is to have the company massively fined and split apart into smaller entities that would be more customer service oriented.
Hopefully the federal agencies will see this massive problem Comcast has become and will act accordingly to resolve it. Comcast has chosen to buy many other smaller cable providers and the experience has been negative for the many of the acquired customers (InsightBB, Time Warner being some). Clearly, those customers were much better off before both technologically and price wise.
Clearly the company does not intend to deliver service to meet the rising demand of the market, nor does it even want to introduce metered access, because even if the customer paid more they would still not be willing to provide the service they already sold, therefore they choose to delve into legalese explanations why really black is white.
Maybe they simply can't. It is difficult to know since they are so opaque in their policies and confused in daily communications. It is too bad that rather than work with the many knowlegeable customers toward a mutually rewarding business relationship the company chooses the heavy handed approach typical of a monopoly, but such is the way sometimes things go.
When they accuse knowlegeable people as Mr. Topolski of not knowing their network, they are only themselves to blame. We, as customers, have as sources of information only confused CSR's or threatening "abuse" department reps that would not even disclose usage caps that supposedly do not even exist. We can draw conclusions only empirically and reactively regarding network architecture and topology vs. preferred cherry picked companies that Comcast chooses to disclose minimal network information to.
We have to deal with the stress of trying to figure out what affects our traffic while we have purchased "unfettered Internet access".
It is important for our country to be a leader in Internet access and development of new technologies as both a promoter of technological growth and as a stream of revenue. The greed of a huge cable video provider should not be the determining factor why this should not happen.

People..and Companies..have every right to defend themselves in this country. And to call into question the knowledge and experience of those making allegations against them.

Any Judge Judy show demonstrates that.

On many occasions on this website you have documented everything from your investigation to your belief that Comcast should even be fined for their actions.

But now you feel they shouldn't have the right to respond to that?

It seems so. And part of that certainly should involve calling into question the experience of those making the allegations. It's the basis of this countries legal system that allows it. And, in fact..demands it in the interest of fairness.

My personal feelings are that while you "uncovered" what you did...I have to call into question for who's benefit was it?
There are millions of us who use the service for reasonable purposes..who aren't "bandwidth hogs"..and who expect our ISP to provide reasonable safeguards against those who degrade our service. I see Comcasts efforts in that light and, while maybe not perfect..I realize that little is in this world. It wasn't a conspiracy to harm their customers.
This company allowed people to download 300 and more gigs per month, has given us 30Mb powerboost speeds..and does it for a reasonable price.

Your portrayal of them has been anything but that IMHO.

With that said..I respect the right you have to your opinions. But..I also respect the right of Comcast to call into question your experience.

It really is only fair.

It was, without a doubt, a benefit to the consumers. It's not about bandwidth hogs, or about the millions of us who use the serve for reasonable purposes - which right there tells me you have no clue. P2P is not illegal - as are mp3 formats not illegal. Yet corporations assume P2P = illegal and Mp3 = illegal.

The benefit was for us. If Comcast wants to block ports, or reset packets, fine, but they have to be upfront and honest about it to us. Then allow consumers to make a decision whether them degrading our service is worth the price or not. Obviously Comcast knows the answer to this, which is why they've been been hush hush about it.

They have every right to question Robb's education and "expertness", and I agree with you - but he has every right to feel that they should be fined for their actions.

Of course sandvine was about bandwidth hogs. Why else would they have utilized it?

And no, every p2p user wasn't doing something illegal..but do you really think that the majority weren't? If you do, I'd suggest you've been living in a dream world for the 7 years you've been on this site.

Like I said..sandvine isn't the perfect solution. But I think their reasoning for it and the category of user it addressed was as right on point as they could possibly make it. Without it..you and I wouldn't be writing this. Our entire networks would be saturated with 24/7 copyrighted p2p activity.

Are there better ways? Perhaps. And, I think the industry and Comcast is now addressing it and hopefully will come to a fair resolution.

As I stated..my critique of funchords wasn't about his right to express himself. I defend that 100%. But, it's also fair that a company then has a right to defend themselves and to call into question the experience of someone who makes allegations against them. My belief over the last few months has been that while he certainly critiqued them..he rarely if ever offered up a better solution and he failed to talk at all about the need to have some controls in place for the benefit of the rest of the users.

That's what I saw as biased and one sided.

Anyways....

I've stated my position.

If, as credible evidence has been given to support, what Comcast was doing was illegal, the first step it to identify and acknowledge the problem. There's no burden on Funchords to provide the solution. To spin and deflect by trying to put the onus on the reporter of the problem is the common strategy of those in denial. A solution will not be found if the problem is denied. Attacking the ethos of your adversary draws the discussion into the realm of name-calling, where the denier might hope to prevail, relying on ignorance of the facts.

If Comcast is so willing to share it's network architecture, then why don't they just publicly share it? I mean, if they're not doing anything wrong, and their network management is "reasonable" then they don't have anything to hide right?

That's the biggest problem to me. They hid the fact that they were "delaying, blocking, covering with mustard, etc" anything from packets to content from their customers. As a customer, it outrages me and I've let them know it several times. I'm not a BT user or P2P guy other than the occasional linux distro or trial app, it's just the fact that they were so deceptive.

I really hope the FCC makes an example of this abuse of their customers.

I don't see what comcast was doing as illegal anymore than I see a bank having the right to install a camera and dye trap in their money drawer as being illegal.

Both companies have the right to protect themselves and their customers from abuse and harm. It has been well documented in many places by many isp's that 5% of users soak up 50% and more of the bandwidth when allowed to continue unabated with their p2p usage. Comcast has every right to call into question the technical expertise of someone making accusations against them because..without some kind of network controls on the 24/7 bandwidth hogging copyright stealing p2p crowd...ALL of our connections would come to a grinding halt because of the limitations of this kind of a shared network.

I've said it before and will say it again. The system is not perfect. And, what also was not perfect is that some people who were using p2p for legitimate means may also have been impacted.

With respect however to funchords..what he didn't do was to acknowledge at all..at least that I saw..that there was a greater common good which comcast and probably most other cable companies were trying to address.
When we go into a bank..we're ALL filmed and perhaps ALL have our privacy imposed on. But it's also for the greater good..and protection of us all.

Anyways...I think the point of this thread isn't that..it's now whether a company or person should have the right to defend themselves. And whether that defense should call into question the experience and expertise of an individual who makes claims against another.

Imagine a witness on a witness stand in a court of law..involved in a malpractice suit against a hospital..telling the jury that everything the doctors did was wrong. Doesn't the defense have the right to ask if that person is even a doctor themselves..and to question their expertise? It seems that what comcast is saying in their filing is that funchords isn't a doctor at all. And has cited evidence of that.

They have the right to do that. And funchords has the right to respond to it and to correct any inaccuracies.

It's only fair.
