How Comcast Censors Political Content
#1
by David Swanson

Most Comcast internet customers seem to have horror stories, but in my humble opinion this one is a doozie and may even suggest threats to freedom of speech more significant than the jailing of a court stenographer.

I'm working on a campaign headquartered at http://www.afterdowningstreet.org that seeks to draw attention to the Downing Street Minutes and to lobby Congress to open an investigation into whether the President has committed impeachable offenses. According to a recent Zogby poll, 42 percent of Americans favor impeachment proceedings if the President lied about the reasons for war, and according to a recent ABC News / Washington Post poll, 52 percent think he did. But this story is nowhere to be found in the corporate media. So, our website attracts a lot of traffic.

In addition, July 23rd is the three-year anniversary of the meeting on Downing Street that produced the now infamous minutes, and we are organizing events all over the country on that day. Or, we're trying to. But we noticed about a week ago that everyone working on this campaign was having strange Email problems. Some people would get Emails and some wouldn't, or they'd receive some but not others. Conference calls were worse than usual (I can't stand the things anyway) because half the people wouldn’t get the info and know where to call in. Organizing by internet is super easy, but when you have to follow up every Email with a phone call to see if someone got it, it becomes super frustrating. Volunteers have been complaining all over the country – especially now that we've figured out what the problem was and they know what to complain about.

We didn't know it, but for the past week, anyone using Comcast has been unable to receive any Email with "http://www.afterdowningstreet.org" in the body of the Email. That has included every Email from me, since that was in my signature at the bottom of every Email I sent. And it included any Email linking people to any information about the upcoming events.

From the flood this evening of Emails saying "Oh, so that's why I haven't heard anything from you guys lately," it seems clear that we would have significantly more events organized by now for the 23rd if not for this block by Comcast.

Disturbingly, Comcast did not notify us of this block. It took us a number of days to nail down Comcast as the cause of the problems, and then more days, working with Comcast's abuse department to identify exactly what was going on. We'd reached that point by Thursday, but Comcast was slow to fix the problem.

During the day on Friday we escalated our threats to flood Comcast's executives with phone calls and cancellations, and we gave them deadlines. Friday evening, Comcast passed the buck to Symantec. Comcast said that Symantec's Bright Mail filter was blocking the Emails, and that Symantec refused to lift the block, because they had supposedly received 46,000 complaints about Emails with our URL in them. Forty-six thousand! Of course, Symantec was working for Comcast, and Comcast could insist that they shape up, or drop them. But Comcast wasn't interested in doing that.

Could we see two or three, or even one, of those 46,000 complaints? No, and Comcast claimed that Symantec wouldn't share them with Comcast either.

By the time Comcast had passed the buck to the company that it was paying to filter its customers Emails, Brad Blog had posted an article about the situation and urged people to complain to Comcast.
http://www.bradblog.com/archives/00001602.htm

Brad quickly added Symantec phone numbers to the story on his website, and we called Symantec's communications department, which fixed the problem in a matter of minutes.

So, why does this matter?

Comcast has a near monopoly on high-speed internet service in much of this country, including much of the Washington, D.C., area. Many members of the media and many people involved in politics rely on it. Three days ago, I almost decided to put a satellite dish on my roof. There's no other way for me to get high-speed internet, unless I use Comcast.

Comcast effectively censors discussion of particular political topics, and impedes the ability of people to associate with each other, with absolutely no compulsion to explain itself. There is no due process. A phrase or web address is tried and convicted in absentia and without the knowledge of those involved.

Now, did Comcast do this because it opposes impeaching the President? I seriously doubt it. Apparently the folks at Symantec did this, and Comcast condoned it. But why?

Well, we have no evidence to suggest that these 46,000 complaints actually exist, but we can be fairly certain that if they do, they were generated by someone politically opposed to our agenda. There's simply no possible way that we've accidentally annoyed 46,000 random people with stray Emails and mistyped addresses. We've only been around for a month and a half, and we haven't spammed anyone. In fact, during the course of trying to resolve the problem, Comcast assured us that they knew we hadn't spammed anyone. And once we'd gotten Symantec's attention, they didn't hesitate to lift the block.

But it had taken serious pressure to find out what the problem was and who to ask for a remedy. We only solved this because we could threaten a flood of negative attention.

This state of affairs means that anyone who wants to stifle public and quasi-private discussion of a topic can quite easily do so by generating numerous spam complaints. The victims of the complaints will not be notified, made aware of the accusations against them, or provided an opportunity to defend themselves. And if the complaints prove bogus, there will be absolutely no penalty for having made them.

And this won't affect only small-time information sources. If the New York Times or CNN attempts to send people Email with a forbidden phrase, it won't reach Comcast customers or customers of any ISP using the same or similar filtering program.

And there is no public list posted anywhere of which phrases are not permitted. This is a Kafkan world. This is censorship as it affects a prisoner who sends out letters and does not know if they will reach the recipient or be destroyed.

What if I had tried to Email someone about a serious health emergency during the past week, but they had been using Comcast and I had been including the address of my website in my Email signature? Is this not a safety issue?

Above all, though, this is a First Amendment issue, as is well laid out in this excerpt of a statement released today by People-Link.org, the organization hosting the http://www.afterdowningstreet.org site:

"This goes far beyond the normal anti-spam measures taken by major providers and represents an effective blocking of constitutionally protected expression and the fundamental right to organize and act politically on issues of concern.

"Most spam blocking measures focus on the email address or the IP address of the suspected spammer. While there are anti-spam measures directed at the body of the email, these usually target attachments that could contain virus programs.

"Targeting the inclusion of a website url can only have one outcome: that communications about that website and the issue it is presenting will be blocked from large numbers of people and that the communications from that site's administrators and the campaign's organizers will not reach their full constituency.

"Whether Comcast's intention or not, this is effectively political and unconstitutional.

"It keeps people from getting valuable information about a campaign that is, in the opinion of many, critical to the future of this country's political system.

"It disrupts the organizing of this campaign and cripples the campaign's ability to use its most effective communications tool: the Internet.

"It damages people's confidence in this campaign since many people who write the campaign can't receive the response they expect and that the campaign has sent.

"Perhaps the worst part of this development is that Comcast has been reportedly doing this without the knowledge of the managers of this website or anyone affiliated with this campaign. In fact, no Comcast customer has received any indication that email to him or her containing this url was blocked."

Comcast blocks some Internet traffic

By PETER SVENSSON, AP Technology Writer

Comcast Corp. actively interferes with attempts by some of its high-speed Internet subscribers to share files online, a move that runs counter to the tradition of treating all types of Net traffic equally.

The interference, which The Associated Press confirmed through nationwide tests, is the most drastic example yet of data discrimination by a U.S. Internet service provider. It involves company computers masquerading as those of its users.

If widely applied by other ISPs, the technology Comcast is using would be a crippling blow to the BitTorrent, eDonkey and Gnutella file-sharing networks. While these are mainly known as sources of copyright music, software and movies, BitTorrent in particular is emerging as a legitimate tool for quickly disseminating legal content.

The principle of equal treatment of traffic, called "Net Neutrality" by proponents, is not enshrined in law but supported by some regulations. Most of the debate around the issue has centered on tentative plans, now postponed, by large Internet carriers to offer preferential treatment of traffic from certain content providers for a fee.

Comcast's interference, on the other hand, appears to be an aggressive way of managing its network to keep file-sharing traffic from swallowing too much bandwidth and affecting the Internet speeds of other subscribers.

Comcast, the nation's largest cable TV operator and No. 2 Internet provider, would not specifically address the practice, but spokesman Charlie Douglas confirmed that it uses sophisticated methods to keep Net connections running smoothly.

"Comcast does not block access to any applications, including BitTorrent," he said.

Douglas would not specify what the company means by "access" — Comcast subscribers can download BitTorrent files without hindrance. Only uploads of complete files are blocked or delayed by the company, as indicated by AP tests.

But with "peer-to-peer" technology, users exchange files with each other, and one person's upload is another's download. That means Comcast's blocking of certain uploads has repercussions in the global network of file sharers.

Comcast's technology kicks in, though not consistently, when one BitTorrent user attempts to share a complete file with another user.

Each PC gets a message invisible to the user that looks like it comes from the other computer, telling it to stop communicating. But neither message originated from the other computer — it comes from Comcast. If it were a telephone conversation, it would be like the operator breaking into the conversation, telling each talker in the voice of the other: "Sorry, I have to hang up. Good bye."

Matthew Elvey, a Comcast subscriber in the San Francisco area who has noticed BitTorrent uploads being stifled, acknowledged that the company has the right to manage its network, but disapproves of the method, saying it appears to be deceptive.

"There's the wrong way of going about that and the right way," said Elvey, who is a computer consultant.

Comcast's interference affects all types of content, meaning that, for instance, an independent movie producer who wanted to distribute his work using BitTorrent and his Comcast connection could find that difficult or impossible — as would someone pirating music.

Internet service providers have long complained about the vast amounts of traffic generated by a small number of subscribers who are avid users of file-sharing programs. Peer-to-peer applications account for between 50 percent and 90 percent of overall Internet traffic, according to a survey this year by ipoque GmbH, a German vendor of traffic-management equipment.

"We have a responsibility to manage our network to ensure all our customers have the best broadband experience possible," Douglas said. "This means we use the latest technologies to manage our network to provide a quality experience for all Comcast subscribers."

The practice of managing the flow of Internet data is known as "traffic shaping," and is already widespread among Internet service providers. It usually involves slowing down some forms of traffic, like file-sharing, while giving others priority. Other ISPs have attempted to block some file-sharing application by so-called "port filtering," but that method is easily circumvented and now largely ineffective.

Comcast's approach to traffic shaping is different because of the drastic effect it has on one type of traffic — in some cases blocking it rather than slowing it down — and the method used, which is difficult to circumvent and involves the company falsifying network traffic.

The "Net Neutrality" debate erupted in 2005, when AT&T Inc. suggested it would like to charge some Web companies more for preferential treatment of their traffic. Consumer advocates and Web heavyweights like Google Inc. and Amazon Inc. cried foul, saying it's a bedrock principle of the Internet that all traffic be treated equally.

To get its acquisition of BellSouth Corp. approved by the Federal Communications Commission, AT&T agreed in late 2006 not to implement such plans or prioritize traffic based on its origin for two and a half years. However, it did not make any commitments not to prioritize traffic based on its type, which is what Comcast is doing.

The FCC's stance on traffic shaping is not clear. A 2005 policy statement says that "consumers are entitled to run applications and services of their choice," but that principle is "subject to reasonable network management." Spokeswoman Mary Diamond would not elaborate.

Free Press, a Washington-based public interest group that advocates Net Neutrality, opposes the kind of filtering applied by Comcast.

"We don't believe that any Internet provider should be able to discriminate, block or impair their consumers ability to send or receive legal content over the Internet," said Free Press spokeswoman Jen Howard.

Paul "Tony" Watson, a network security engineer at Google Inc. who has previously studied ways hackers could disrupt Internet traffic in manner similar to the method Comcast is using, said the cable company was probably acting within its legal rights.

"It's their network and they can do what they want," said Watson. "My concern is the precedent. In the past, when people got an ISP connection, they were getting a connection to the Internet. The only determination was price and bandwidth. Now they're going to have to make much more complicated decisions such as price, bandwidth, and what services I can get over the Internet."

Several companies have sprung up that rely on peer-to-peer technology, including BitTorrent Inc., founded by the creator of the BitTorrent software (which exists in several versions freely distributed by different groups and companies).

Ashwin Navin, the company's president and co-founder, confirmed that it has noticed interference from Comcast, in addition to some Canadian Internet service providers.

"They're using sophisticated technology to degrade service, which probably costs them a lot of money. It would be better to see them use that money to improve service," Navin said, noting that BitTorrent and other peer-to-peer applications are a major reason consumers sign up for broadband.

BitTorrent Inc. announced Oct. 9 that it was teaming up with online video companies to use its technology to distribute legal content.

Other companies that rely on peer-to-peer technology, and could be affected if Comcast decides to expand the range of applications it filters, include Internet TV service Joost, eBay Inc.'s Skype video-conferencing program and movie download appliance Vudu. There is no sign that Comcast is hampering those services.

Comcast subscriber Robb Topolski, a former software quality engineer at Intel Corp., started noticing the interference when trying to upload with file-sharing programs Gnutella and eDonkey early this year.

In August, Topolski began to see reports on Internet forum DSLreports.com from other Comcast users with the same problem. He now believes that his home town of Hillsboro, Ore., was a test market for the technology that was later widely applied in other Comcast service areas.

Topolski agrees that Comcast has a right to manage its network and slow down traffic that affects other subscribers, but disapproves of their method.

"By Comcast not acknowledging that they do this at all, there's no way to report any problems with it," Topolski said.
