There ’s a good ground why you do n’t know how your data gets from one place to another on the net . The major mesh cables that truss the United States have n’t ever been fully viewable to the public – until now .
In 2006 , the US Senator Ted Stevens used a strand of four words to describe the internet : A serial of tubes . That phrase would become iconic , a running punchline about the oblivion of politicians in the net age . They ’re also invoke by a group of scientist behind the first public function of the net ’s major routes across the US . The group , led by University of Wisconsin ’s Paul Barford , say it ’s just another example of how fiddling we really bonk about the most permeative resourcefulness of the advanced years . The name of their paper even nods to Stevens – InterTubes : A Study of the US Long - draw Fiber - optic Infrastructure .
“ Despite some 20 eld of research efforts that have focused on understanding aspect of the cyberspace ’s base , ” they compose in the paper , whichMIT Tech Review ’s Tom Simonite pointed out week , “ very little is know about today ’s physical cyberspace where single components such as cellphone towers , router or switches , and fiber - oculus cable’s length are concrete entities with well - defined geographic locations . ”
As the debate over net neutrality grows , our ignorance of the forcible infrastructure of the web is really becoming a liability .
Drawing the Internet
The undertaking to map the cyberspace ’s byway began in 2011 accordingto a display by Barford , when his team set out to figure out where the major cable television plug into the US are in reality located .
These are n’t the association that bring the internet from a datum center to your business firm . They ’re “ recollective - haul ” routes that blast data between major cities — the fiber optic interstates of the web . Because most of these connection were built by ISPs and providers like Comcast , EarthLink , and AT&T , it ’s not as gentle as get at public information on a government website .

or else , they had to do serious tec body of work to piece together the routes . While some ISPs provide maps of their long - catch cables , others had to be investigated through secondary sources like public book . They accessed governing documents permitting process that top to construction , or environmental impact statements about installation , or even the agreements between Department of State governance about the cable .
For example , they only instruct about a cable in Colorado thanks to an FCC subject area about the broadband surround that described shared cables by Comcast and other ISPs there . Other public document showed cables at unlike points of installation , from permitting to construction , helping the mathematical group develop a work map of major cablegram .

Still , the process of patch together this information read a huge amount of work . They decided to produce a measure for which cables certified as prospicient haul – it had to either connect cities of at least 100,000 people , be farsighted than 30 miles , and it had to be a cable shared by two providers .
Why did they care about which ISPs apportion base ? Because the whole tip of the written report was to understand the risks link with the current cyberspace map – if many ISPs deal the same cable , that tells us a mass about a potential risk of exposure spot . For example , in one instance they found that some conduits were shared by as many as 19 different ISPs , including major connection like the one between Denver and Salt Lake City , or Philly and New York City .
The final map , published intheir paperand presented atSIGCOMM this August , is a tangled ladder of scraggy lines that include 273 metropolis or hub and 2,411 links . It ’s the “ first of its kind , ” the authors say , but it ’s far from all over . They ’ve created asite for the projection , which is now being expanded to include undersea cable length and connection from other res publica .
“ Our finish in developing this archive and the associated vena portae is to use it as the ground - truth fundament to cover a variety of significant dubiousness on net robustness , performance , manageability and security , ” Barford told me over e-mail this week .
Who Cares Where the Internet Comes From?
Here ’s an significant question : Why does it matter where the cyberspace goes ? Is n’t it robust enough that it ’ll survive any specific attack or nonstarter ?
Sure . The internet , by sexual morality of its spiderweb - like redundance , is reasonably bloody full-bodied . But the paper also aim out how dependent we are on it functioning , not just for YouTube but for the persistence of major infrastructure systems , security , and communication . If we do n’t cognise where the succus that connect those system comes from , we do n’t have much recourse in protecting them when they fail , or if they ’re attacked .

Then there are the huge political implications of the web ’s strong-arm cosmos . The debate over nett disinterest focuses on whether ISPs should beclassified as public utilities – which could be regulate by the FCC – or whether they should remain private entities . In that case , the physical stuff , the cable and trenches and connection that Barford and his confederate have mapped , would become public substructure , usable to third party to access , despite whatever ISPs shared the cost to build them . More carriers will share the same old base .
One big issue of Title II allowing other carriers to access these existing long - haul cable is that sharing existing cables wo n’t increase the number of redundancies in the organization . Because more carrier will be using the same existing routes , there will be less redundancy . It ’s an “ unavoidable trade - off , ” the authors say , and one that should be part of the net neutrality public debate .
Another interesting full point made by the paper ? Look at their map of the internet , and you ’ll see a rough proxy for other , old systems that connect the US . It reckon a pile like the interstate map , as the study taper out , as well as the railway mapping . That ’s no surprisal — our city are in the same places , and in many cases these cables have been lay down in subsist oceanic abyss hold substructure .
But should the net mimic the bodily structure of other system from former 100 ? Over electronic mail , Barford said the team ’s current focus is evolve slipway to diminish the danger of partake a few major cables using a system based on Internet eXchange Points . Known as IXPs , these would be forcible hub where ISPs could exchange traffic freely and make greater redundancy and abject lag than the current connection . Perhaps province would even collaborate and support these hubs .
The body of work continues on the map , which is now being expanded to a ball-shaped scale of measurement . But maybe the most of import takeout from the task ? The fact that , while lawmakers debate the time to come of cyberspace infrastructure in America , there has n’t been much information available about what it really looks like – where the risks are , who carries that risk , and what can be done to mitigate it . In the end , the authors are n’t arguing for or against a specific approach to regulating net – they’re offer very useful evidence about it .
