The Urge to Create

A recent Wired article reminded me of the first time a friend tipped me off to the then-new Red vs. Blue videos (beware salty language, adult themes). At the time, I found it hilarious and didn't give a thought to it ever being called "The Future of TV." Now called "machinima," it has exploded among video game enthusiasts and reminds me of just how much people like to create their own content. The big cable and telephone companies want us to believe that our upstream connections should be much slower than our downstream, encouraging us to consume content rather than creating it. It did not take long after giving people video games that they wanted to create their own levels and share them. Even before there was a place to easily host video, people were writing scripts to turn a video game into a sitcom and sharing it. From the Wired article:
“It’s part of a larger cultural shift in gaming,” Jones says. “This generation doesn’t watch television in the same way. They want to create. We’re giving them something that television isn’t.”
The Machinima videos have collectively surpassed 2.5 billion views. That is a lot of consumption, but it wouldn't have been possible without a mechanism for some creative folks to easily share their new idea. We need robust connections in both downstream and upstream to make the most of the Internet. The only reason to limit the upstream is to enforce consumer behavior, which diminishes us all.

WindomNet Turns on Southwest Minnesota Broadband Services

Exciting times in rural southwest Minnesota, as Southwest Minnesota Broadband Services has turned on its first customer. SMBS is a broadband stimulus-enabled partnership with eight rural communities and WindomNet, the muni FTTH network in Windom.
The Rev. Andrew Schensted and his wife, Lisa, were the first to be connected. The fiber-to-home connection provides “obnoxiously fast Internet,” Andrew Schensted said in a SMBS press release. The SMBS Internet is “at least 10 times faster” than what they had when living in the metropolitan area, Andrew Schensted added. The couple has been able to streaming video in full HD from TV streaming websites.
So it begins... the Metro around Minneapolis and St Paul have to rely mostly on Comcast for connections to the Internet. CenturyLink's DSL is generally slower and in many places, utterly unreliable. Monticello has had a blazing fast connection (faster than we can get in the metro) at lower prices for more than a year. Communities served by HBC also have faster connections in SE Minnesota. In the coming year, the stimulus-funded networks on the North Shore will also have better connections than we can get. It will be curious to see how development patterns adjust in the coming years.
“The demand for higher-speed Internet in our rural area is daunting,” Olsen said. “People not only want faster speeds, they need it for their business operations. If the wireless trial is successful, it could provide a better option to those not on the fiber system. “ Southwest Minnesota Broadband Services (SMBS) is a consortium of eight communities including Bingham Lake, Brewster, Heron Lake, Jackson, Lakefield, Okabena, Round Lake and Wilder. The 125-mile, $12.8 million dollar fiber ring is expected to be completed in September 2012. The fiber-optic communication network has the capacity to bring fast, competitively priced services for internet, phone and cable TV to residential subscribers as well as businesses and other community institutions. The government grant-supported project is intended to provide southwest Minnesota with the telecommunications connectivity required to remain competitive in the global marketplace.
The new network has bucked a strong trend among community fiber networks of offering symmetric connections to the Internet.

The Internet is More Important than Broadband

I encourage readers to visit Doc Searls post "Broadband vs. Internet" for a discussion about things that matter regarding the future of Internet access for most Americans.
The Internet is no more capable than the infrastructures that carry it. Here in the U.S. most of the infrastructures that carry the Internet to our homes are owned by telephone and cable companies. Those companies are not only in a position to limit use of the Internet for purposes other than those they favor, but to reduce the Net itself to something less, called “broadband.” In fact, they’ve been working hard on both.
There is a difference between the Internet and "broadband." Broadband is a connection that is always on and tends to be somewhat faster than the dial-up speeds of 56kbps. Broadband could connect you to anything... could be the Internet or to an AOL like service where some company decides what you can see, who you can talk to, and the rules for doing anything. The Internet is something different. It is anarchic, in the textbook definitional sense of being leaderless. It is a commons. As Doc says,
The Internet’s protocols are NEA:
  • Nobody owns them.*
  • Everybody can use them, and
  • Anybody can improve them.
Because no one owns it, few promote it or defend. Sure, major companies promote their connections to it (and when you connect to it, you are part of it) but they are promoting the broadband connection. And the biggest ones (Comcast, AT&T, Verizon, Time Warner Cable, etc) will do anything to increase the profits they make by being one of the few means of connecting to the Internet -- including charging much more and limiting what people can do over their connection, etc. This is one reason the connections from major corporations are so heavily tilted toward download speeds -- they want consumers to consume content. Just about every community network built in the last 3-4 years offers symmetrical connections by contrast.
Last I heard, the fastest cable offering in the upstream direction was 12Mbps. Cox, our cable provider in Santa Barbara, gives us about 25Mbps down, but only 4Mbps up. Last time I talked to them (in June 2009), their plan was to deliver up to 100Mbps down eventually, but still only about 5Mbps up.

Rural Washington Network, Chelan PUD, Increases Speeds and Expands

The Chelan Public Utility District in Washington state is upgrading network capacity as it starts expanding the network following its broadband stimulus award. We previously covered their consideration of whether to expand from passing 80% of the territory to 98%. Chelan is one of the most rural publicly owned fiber networks as well as one of the oldest ones. In a rarity, it looks likely to run in the red permanently (the pains of rural, mountain terrain) with the support of most ratepayers. These ratepayers recognize the many benefits of having the network outweigh its inability to entirely pay for itself. The utility also runs a sewer project that is subsidized by wholesale electricity sales. Though some areas in Chelan are served by Charter and Frontier, the more remote folks would have no broadband access if not for the PUD. With the planned upgrades in 2011, Chelan's open access services will offer far faster speeds than available from the cable and DSL providers. Under Washington law, the PUDs cannot sell telecommunications services directly to customer. The PUD builds the network infrastructure and allows independent service providers to lease access while competing with each other for subscribers. Though this is a great approach for creating a competitive broadband market, it has proved difficult to finance (if one believes this essential infrastructure should not be subsidized as roads are). When the PUD considered whether to pursue the expansion (meaning taking a federal grant covering 75% of the costs and agreeing to run the network for 22 years), it asked the ratepayers for feedback:
Sixty-four percent of 450 randomly chosen Chelan County registered voters who were part of phone survey in August said they favor taking the grant and completing the buildout, even if it means their electric bills will go up by as much as 3 percent — about $1.50 more on a $50 per month power bill.
On November 9, PUD Commissioners approved the rate increase. Chelan's service providers currently offer connections of 6Mbps/384kbps or 12 Mbps/384kbps.

Comcast, Level 3, Peering, and a Bad Best Case Scenario

So Comcast and Level 3 are in a peering dispute following the Netflix partnership with Level 3 to distribute their streaming movie service. Studies suggest Netflix movie streaming has become a significant chunk of Internet traffic, particularly at peak times. A quick primer on peering: the Internet is comprised of a bunch of networks that exchange traffic. Sometimes one has to pay another network for transit and sometimes (commonly with big carriers like Comcast and Level 3) networks have an agreement to exchange traffic without charging (one reason: the costs of monitoring the amount of traffic can be greater than the prices that would be charged). (Update: Read the Ars Technica story for a longer explanation of peering and this conflict.) Comcast claims that Level 3 is sending Comcast 5x as much traffic as Comcast sends to Level 3 and therefore wants to charge Level 3 for access to Comcast customers. Of course, as Comcast only offers radically asymmetrical services to subscribers, one wonders how Level 3 could be 1:1 with Comcast… At Public Knowledge, Harold Feld ties the dispute to network neutrality:
On its face, this is the sort of toll booth between residential subscribers and the content of their choice that a Net Neutrality rule is supposed to prohibit.  In addition, this is exactly the sort of anticompetitive harm that opponents of Comcast’s merger with NBC-Universal have warned would happen — that Comcast would leverage its network to harm distribution of competitive video services, while raising prices on its own customers.
Susan Crawford Susan Crawford wrote a lengthier piece about Comcast, Netflix, network neutrality, set-top boxes and NBC that is well worth reading (as is just about anything she writes).

Putting Shareholders and Profits ahead of the Community

One of the key differences between community owned networks and those driven by profit is customer service. Community-driven providers spend more and create more jobs in the community to ensure subscribers' needs are met. The massive private companies instead choose to outsource the jobs to call centers (sometimes in the U.S., sometimes outside) in order to cut costs (and jobs - see the report from the Media and Democracy Coalition). We've seen a few examples of the big carrier approach in this arena - as when Cablevision billed apartment residents $500 after a fire for the DVR that was consumed in the blaze... stay classy, Cablevision. Another difference between community networks and the big carriers is that big carriers see little reason to upgrade their anemic networks to ensure communities remain competitive in the digital age. As Free Press has long documented [pdf] big companies like AT&T have been investing less in recent years as the U.S. has continued falling in international broadband rankings. Up here in Minnesota, Qwest has invested in FTTN - what they call fiber-to-the-node. We call it Fiber-to-the-Nowhere. For those who happen to live very close to the node, they get slightly faster DSL speeds that are still vastly asymmetrical. Meanwhile, Qwest has branded this modest improvement for some as "fiber-optic fast" and "heavy duty (HD)" Internet, misleading customers into thinking they are actually going to get faster speeds than Comcast's DOCSIS 3. Much as I hate to praise the middling DOCSIS 3 upgrade, it certainly offers a better experience than any real results we have seen with Qwest. But as we carefully documented in this report, community networks offer more for less. Two friends recently moved to Qwest. One, J, was convinced by a Qwest salesperson that Qwest would be much faster so he signed up for a 20Mbps down package.

A Public Interest Internet Agenda

Image
The Media and Democracy Coalition put together an impressive report examining a number of policy options to put communities first in telecommunications infrastructure. The report discusses the fundamental importance of broadband - noting that it enables the right to communicate. Having establishing its importance, the report notes that good policy must be well informed and goes on to make multiple recommendations.
Policy should promote competition, innovation, localism, and opportunity. Locally-owned and -operated networks support these core goals of Federal broadband policy, and therefore should receive priority in terms of Federal support. Structural separation of ownership of broadband infrastructure from the delivery of service over that infrastructure will further promote these goals.
The report also touches on other key issues - including Universal Access, a non-discriminatory Internet (network neutrality), symmetrical connections, and privacy. But the most important focus from our perspective is that of localism:
For decades, American communities — both rural and urban — have been neglected and underserved by absentee-owned networks, whose business models clearly do not work in smaller or economically challenged communities. By contrast, in the communities in which they are based, locally-owned networks are more likely than absentee-owned networks to provide rapid response to emergencies, enhanced services, and value-added, social capital benefits such as job-training, youth-mentoring, and small business incubation. In addition, local networks are less likely to outsource jobs, thereby strengthening local and regional economies, while creating more opportunities for community-based innovation and problem-solving. Federal broadband policy that prioritizes support for local networks will produce more competitive markets, consumer choice, and opportunities for innovation.
The first two recommendations in this section calls for federal policy that discourages absentee ownership:
  1. To fulfill the goal of extending broadband service to un- and underserved areas, federal broadband policy should prioritize support for locally-owned and -operated networks, including those owned by local governments, nonprofits and cooperatives, and public-private partnerships.

Community Fiber Networks, Symmetry, and the Flu

Many publicly owned community fiber networks offer symmetrical connections - allowing subscribers to both upload and download content at the same speeds. This approach treats the subscriber as both a producer and consumer of content (one of the reasons I generally avoid calling a subscriber a "customer" or "user"). Nearly all private network offerings are asymmetrical - DSL and cable are more less subject to constraints that encourage asymmetry, but in the case of fiber, one might assume that private companies are generally more interested in selling content to subscribers rather than encouraging them to create their own. These companies have generally argued that symmetrical connections are just not necessary because most people are inherently more interested in downloading content than uploading - and note that on existing networks, people tend to download more than they upload. However, the aggregate data of some 7,000 users on a fast, symmetrical network in Europe suggests that when subscribers have the opportunity, their upload usage balances the downstream usage. We should continue pushing for increased upstream capacity from providers - especially providers that have to listen to their community. As for absentee-owned companies only interested in profits, well, good luck. Which brings me to the flu. One would rationally expect that when a profit-maximizing company builds a telecommunications network, it will make different trade-offs when it comes to redundancy and spare capacity. Planning for high-impact, low probability events is not as high on the priority list of a company looking out first for shareholder interests. On the other hand, communities are more likely to be concerned. Suburban community Lakeville in Minnesota, has been significantly motivated in its attempts to improve fast broadband access by a recognition that an epidemic or pandemic would leave the community paralyzed and its networks unable to cope with a many telecommuters. DSL and cable networks cannot handle a sudden surge in usage.
