For many people, going without the internet fifty-fifty for a few hours is unthinkable. Simply if it did stop working, the impact might not exist what you lot'd await.

Jeff Hancock likes to give his Stanford University students weekend assignments that permit them experience concepts discussed in class for themselves. Earlier 2008, he would sometimes challenge his students to stay off the net for 48 hours and then hash out how it affected them. But when Hancock returned to work in 2009, subsequently a yr-long sabbatical, things had changed.

"When I tried to introduce the job, there was a class revolt," says Hancock, who studies the psychological and social processes involved in online communication. "The students emphatically said the assignment was impossible and unfair."

They argued that going offline even for a weekend would prevent them from completing work in other classes, ruin their social lives, and make their friends and family worry that something terrible had happened to them. Hancock had to concede and cancelled the activeness – and he's never attempted information technology over again. "That was 2009, and now with mobile every bit present as it is, I don't even know what students would practice if I asked them to do that," he says. "They'd probably study me to the university president."

Just with our always-connected lifestyles, the question is now more relevant than ever: what would happen if the internet stopped for a 24-hour interval? It turns out the impact might non be quite what yous'd look.

In 1995, fewer than 1% of the world'due south population was online. The internet was a curiosity, used mostly past people in the West. Fast-forward 20 years and today more than 3.5bn people take an internet connection – virtually half of all humans on the planet – and the number is growing at a rate of effectually 10 people a second.

According to the Pew Research Middle, a fifth of all Americans say they use the internet "almost constantly" and 73% say they use it at least daily. Figures in the UK are similar: a 2016 survey found that nearly xc% of adults said they had used the cyberspace in the previous three months. For many, it is now well-nigh impossible to imagine life without the cyberspace.

"One of the biggest problems with the net today is that people take information technology for granted – nonetheless they don't understand the caste to which we've allowed it to infiltrate almost every aspect of our lives," says William Dutton at Michigan State University, who is the author of the book Society and the Internet. "They don't even think well-nigh not having admission to it."

But the net is not inviolable. In theory, it could be taken abroad, on a global or national scale, for a stretch of time. Cyberattacks are one possibility. Malicious hackers could bring the net to a standstill past releasing software that aggressively targeted vulnerabilities in routers – the devices that forward internet traffic. Shutting down domain name servers – the cyberspace'south address books – would also cause massive disruption, preventing websites from loading, for example.

Cut the deep-sea cables that behave vast volumes of net traffic between continents would also cause significant disruptions by disconnecting ane part of the world from another. These cables may not be easy targets for attackers, but they are sometimes damaged accidentally. In 2008, people in the Middle East, India and Southeast Asia were plagued by major internet outages on iii separate occasions when submarine cables were cut or interfered with.

Some governments also have "impale switches" that can effectively turn off the cyberspace in their country. Egypt did this during the Arab Leap uprising in 2011 to arrive more difficult for protesters to coordinate their activity. Turkey and Islamic republic of iran take besides close off internet connectivity during protests. Mainland china is rumoured to have a kill switch of its own. And American senators accept proposed creating one in the US equally a means to defend the state from cyberattack.

Edifice a kill switch is not easy, even so. The larger and more developed the country, the harder information technology is to close down the internet completely – there are simply too many connections between networks both within and outside national borders.

The most devastating strikes could come up from space, however. A large solar tempest that sent flares in our direction would take out satellites, ability grids and calculator systems. "What bombs and terrorism can't exercise might be accomplished in moments by a solar flare," says David Eagleman, a neuroscientist at Stanford University and writer of Why the Internet Matters. "The next major geomagnetic storms are eventually coming."

Simply well-nigh outages would not last long. "There's an army of people gear up to put things correct," says Scott Borg at the The states Cyber Consequences Unit of measurement, a not-profit organisation. "The cyberspace service providers and the companies that make the routing equipment have plans and personnel in place for getting things up and running once more if unexpected vulnerabilities are exploited." We are and so used to having an e'er-on net connection that even relatively brusque disruptions would have an result, however. It just might not exist what you would expect.

For a commencement, the impact to the economy may not be as well astringent. In 2008, the The states Department of Homeland Security asked Borg to expect into what might happen if the net went downwards. Borg and his colleagues analysed the economic effects of figurer and net outages in the US from 2000 onwards. Looking at quarterly financial reports from the twenty companies that claimed to be most affected in each instance, besides every bit more general economic statistics, they discovered that the fiscal impact of an outage was surprisingly insignificant – at to the lowest degree for outages that lasted no more than than four days, which is all they studied.

"These were instances where enormous losses were being claimed– in the hundreds of millions and even billions of dollars," Borg says. "But while some industries like hotels, airlines and brokerage firms suffered a fleck, fifty-fifty they didn't experience very big losses."

It turned out that losing internet access for a few days just made people fall behind on their work. "People carried out yet activities they would have done had the cyberspace been up, but they just did information technology 2 or three days later," Borg says. "The economy is gear up to bargain with what essentially amounts to a holiday weekend."

In some cases, shutting down the cyberspace for a short fourth dimension might even increment productivity. In some other study, Borg and his colleagues analysed what happened when a visitor suffered an internet outage that lasted 4 hours or more than. Rather than twiddle their thumbs, employees did things that they would unremarkably put off, such as dealing with paperwork. The result was a boost for concern. "We jokingly suggested that if every company turned off their computers for a few hours each month and made people do the tasks they postponed, there'd be an overall productivity benefit," Borg says. "I meet no reason why that wouldn't also utilize to basically the whole economy."

Travel probably would not be affected too much in the brusque term, either – then long as the blackout lasted no more a day or so. Planes can fly without the internet, and trains and buses would go along to run. Longer outages would commencement to take an effect on logistics, notwithstanding. Without the net it would be hard for businesses to operate. "I've suggested that people and businesses should have a plan in place in the consequence of internet loss, but I oasis't heard of anyone doing that yet," Eagleman says.

A large communication breakdown would probably disproportionately touch on small businesses and blue-collar workers. In 1998, as many equally 90% of the fifty million pagers in the The states stopped working because of a satellite failure. In the days following the blackout, Dutton surveyed 250 pager users in Los Angeles and found clear socioeconomic divisions in people's reactions to being cut off. Upper-middle-class individuals with managerial or professional jobs did not perceive the outcome as largely problematic. "To them, it felt like a snow day," Dutton says. "It was a relief."

Only many blue-collar freelancers such as plumbers and carpenters relied solely on their pagers for getting jobs and establish themselves out of piece of work for a few days. Unmarried mothers who left their children at daycare as well reported significant distress at not being able to exist paged if a problem occurred. "So you accept to realise that your reaction to the idea of losing the cyberspace is likely to be based on your socioeconomic condition," Dutton says.

Psychological effects, similar feelings of isolation and anxiety, would hit people across the lath, all the same. "Most of the internet is designed for one purpose: to allow us to communicate with each other," Hancock says. We are used to existence able to connect to anyone, anywhere and at any time. "An inability to do that would exist unsettling." It's a feeling Borg recognises too. "I know when I realise I've left my smartphone behind, I experience slightly naked," he says. "I suddenly accept to think, 'Do I actually know where I'm going? What if my machine breaks down, could I talk anyone into letting me utilise their phone to call for help?'"

History supports this. In 1975, a burn down at the New York Telephone Company cutting off the phone service in a 300-block area of Manhattan for 23 days. In a survey of 190 people carried out immediately after lines were restored, researchers establish that four-fifths of respondents said they missed the telephone, especially its power to connect them with friends and family. Over ii-thirds said the lack of service made them experience "isolated" or "uneasy," and near three-quarters said they felt more in control when their service was restored.

"There's this idea that maybe people would become more social and more in touch with friends and family if they didn't accept use of the internet, but I think that's really mistaken," Dutton says. "Most people using the internet are actually more social than those who are not using the internet."

Stine Lomborg at the University of Copenhagen agrees. "It's non like we'd be more likely to speak to strangers at the bus stop if nosotros didn't have our smartphones – not at all," she says. The loss of connexion may brand people more social in specific situations, such equally forcing co-workers to speak to each other rather than sending emails, but overall the experience is likely to be distressing. "The world wouldn't fall apart if nosotros didn't have access to the internet for a day," she says. "Only for most people I recollect even one day without information technology would exist terrifying."

The feeling would be fleeting, withal. Losing the cyberspace may make people recognise its importance in their lives, but nosotros would presently exist taking it for granted again, says Hancock. "I'd like to say an internet blackout would crusade a shift in our thinking, but I don't think it would." Still, that's even so not plenty to persuade his students to give it up for a weekend.
