Fart | Hvilket land tror du har verdens nest kjappeste internetthastighet?

35 petabytes og 27 millioner nedlastinger fra 224 land senere har Pando Networks målt internetthastighet i alle kriker og kroker av denne kloden.

Kina er nummer 82 i verden, USA er 26. Vinneren, Sør Korea, har verdens hurtigste hastighet. Faktisk raskere enn UK, Tyrkia, Spania og Australia – tilsammen.

Her er topp 10:
Screen shot 2011 09 26 at 20 56 41 Romania, Bulgaria, Litauen og Latvia er alle topp 5. Sverige og Danmark slår oss. I Congo kan ikke lyden av et modem ikke være langt unna.

Norge har en hastighet på 802 KBps, og er akkurat utenfor topp 10.

Hvordan hai angriper internett. Nei, seriøst. Hai.

Jeg visste det var mange over Atlanterhavet, men ikke så mange vestover fra California. Og jeg visste om trålere, men ikke om haiene:

The Internet is, in fact, a series of tubes:

“The Internet is a series of tubes,” the late Sen. Ted Stevens infamously rem<rked in a 2006 speech on net neutrality. The quote quickly went viral, harshly mocked by the “Daily Show” and dozens of amateur YouTube users.

But Stevens was kind of right. The physical structure that gets Internet data from one point to another is, in fact, a bunch of tubes, or submarine cables. And you can see exactly what those cables look like in a very cool, interactive map released today by data firm Telegeography. It shows the network of 188 existing and planned submarine cables used to carry Internet data (you can play with an interactive version of the map here):

Only 10 percent of Internet traffic currently moves through satellites. So this actually is a pretty good map of how most of the Internet’s data travels: through more than a half-million miles of privately owned, three-inch thick, submarine cables (and, once those hit land, above-ground cables).

Sometimes, the tubes that carry the Internet break. The causes can range from natural disruptions — an undersea earthquake, for example — to ship anchors digging up cables. The most common problem is fishing nets dragging cables up, although the cables have also had to fend off sharks (shark bites cause damage to Internet cables every year, according to the International Cable Protection Committee). Serious damage can break the tubes; a 2006 underwater earthquake off the coast of Taiwan, for example, brought service there to a screeching halt. There is actually a whole fleet of ships dedicated to fixing the Internet’s damaged cables. Popular Mechanics wrote a fascinating story about them a few years ago. The ships use sonar, video cameras and a multimillion-dollar remotely operated vehicle affectionately named “The Beast” to locate and fix damaged cables.

So, the late Sen. Stevens was pretty accurate in describing the Internet as a series of tubes — and probably among the most important and best-cared-for tubes out there.

Internett og lokale lønninger: Et mysterium

Jeg likte denne. Ikke noe man leser hver dag.

«The Internet and Local Wages: A Puzzle»:

This is from a description of new research forthcoming in the American Economic Review, ‘The Internet and Local Wages: A Puzzle,’ by Avi Goldfarb, Chris Forman and Shane Greenstein:

What has the Internet Done for the Economy?, Kellogg Insight: …There is widespread optimism among media commentators and policy makers that the Internet erases geographic and socioeconomic boundaries. The Death of Distance and The World Is Flat, two books that espouse that rosy view, were bestsellers. But in the early days of the Internet, the income gap between the upper and middle classes actually began to grow. ‘We thought it was just a very natural question to ask: is the Internet responsible?’ Greenstein says.

Misplaced Optimism
The researchers studied trends from 1995 to 2000 in several large sets of data, including the Quarterly Census of Employment and Wages—which gives county-level information on average weekly wages and employment—and the Harte Hanks Market Intelligence Computer Intelligence Technology Database, which holds survey information about how firms use the Internet. In total, the researchers included relevant data for nearly 87,000 private companies with more than 100 employees each. Based on their older work, they focused only on advanced Internet technologies.

Out of about 3,000 counties in the U.S., in only 163 did business adoption of Internet technologies correlate with wage and employment growth, the study found. All of these counties had populations above 150,000 and were in the top quarter of income and education levels before 1995. Between 1995 and 2000, they showed a 28 percent average increase in wages, compared with a 20 percent increase in other counties (Figure 1).

Figure 1. Advanced Internet investment and wage growth by county type.

Why did the Internet make such big waves in these few areas? Greenstein believes the reason was that these areas already had sophisticated companies and the communications infrastructure needed to seize on the Internet’s opportunities. But there are other possibilities. The impact could have been due to a well-known phenomenon called ‘biased technical change,’ which means that new technologies can thrive only in places with skilled workers who know how to use them. Or it could have been because cities brought certain advantages—denser labor markets, better communication, tougher competition—than more remote areas.

‘Each one of those explanations is plausible in our data, and probably explains a piece of it. But none of them by themselves can explain the whole story,’ Greenstein says. ‘It’s really a puzzle.’ …
