For all the good it does, Twitter is a black hole, because it’s centralized. Fortunately the Internet, by design, is not. On March 14, 2014, . Prime Minister announced, “We now have a court order. We’ll eradicate Twitter. I don’t care what the international community says. Everyone will witness the power of the Turkish Republic.” ( ) He also said Turkey would “rip out the roots” of Twitter. ( ) Turkey shut down Twitter Recep Tayyip Erdoğan Hurriyet Daily News Washington Post Yes, and when I was in Istanbul last week, Twitter worked fine. That’s because Twitter’s roots are in the Internet. Even if Turkey rips the roots out of the phone and cable systems that provide access to the Net, they can’t rip out the Net itself, because the Net is not centralized. It is distributed: a rather than a hierarchy. At the most basic level, the Net’s existence relies on rather than on how any .com, .org, .edu or .gov puts those protocols to use. heterarchy protocols The Net’s protocols are not servers, clouds, wires, routers or code bases. They are about how data flows to and from any one end point and any other. This makes the Internet a rather than a world of governments, companies and .whatevers: a . It cannot be reduced to any of those things, any more than time can be reduced to a clock. The Net is as oblivious to usage as are language and mathematics — and just as supportive of every use to which it is put. And, because of this oblivity, The Net supports all without favor to any. agreements world of ends giant zero between everybody and everything on it By design, anyway. Implementation is another matter, because access is provided in most cases by institutions, which are all by nature centralized. They think in centralized ways and with centralized interests. Like the lines, triangles and squares in , they have trouble making sense of a sphere in their midst. But they need to. . The Internet’s giant zero is exactly that sphere. And it’s still new, having come into being on 30 April 1995, when (in , commercial activity), . After that, all forms of data traffic were allowed, and supported, by the Net’s base protocol and therefore the Net itself. Flatland We all do the last transit route within the Internet that forbade one kind of data cargo that case stood down It helps to go back to first principles. laid those out in the early 1960s when he contrasted centralized systems (such as governments), decentralized ones (such as Twitter+Facebook+Google, etc.) and distributed ones, : Paul Baran using this drawing Design C was put to use for the Internet. One difference: The lines don’t need to be there, and any one of them can connect with any other one, through a middle that’s as oblivious to what it does for everything on it as the core of the Earth is to what happens on its surface. In , called the Internet “stupid.” Like gravity, there’s nothing smart about it. this landmark paper David Isenberg Baran’s design appealed to military folks because the “attack surfaces” of a distributed system are no larger than a single node or a single connection, so it’s much harder to bring the whole thing down. This is why “The Internet interprets censorship as damage and routes around it.” This happened in Turkey two years ago, just as it happens today in China and other countries that use their privileged and centralized controls to sphincter services on the Net that they don’t like. John Gillmore says And countries aren’t the only culprits. These days it seems almost impossible to be social or do business on the Net without dwelling, at least some of the time, in the deep gravity wells of Facebook, Twitter, Amazon, Instagram and the rest. But getting around them is still do-able . That design is not about hard and fixed administrated lines, but about the voluntary connections supported by the Net’s protocols in the first place. by design For example, despite its size, Twitter is no more than one dot in the star-shaped designs of Baran’s A and B. That dot becomes a true black hole when powerful actors like the Turkish and Chinese governments “eradicate” it. When that happens, no light escapes. The biggest gravity wells have the biggest attack surfaces. We need to bear this in mind when we design and use centralized systems — and even decentralized ones. Only distributed systems, each no larger than one node, are fully respectful of the Net’s distributed nature. And no, designing for that is not impossible. Everything on Earth is also distributed in its own use of gravity. You aren’t pulled toward the ground because some company provides you a gravity service. To design for full Net compliance, you need to follow Steve Jobs’ role models. think different Before I give my examples, I’d like to hear yours. (Just being distributed here.)
