For many people, going without the internet even for a few hours is unthinkable. But if it did stop working, the impact might not be what you'd expect.

Jeff Hancock likes to requite his Stanford Academy 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 internet for 48 hours then discuss how it affected them. But when Hancock returned to work in 2009, afterward a year-long sabbatical, things had changed.

"When I tried to introduce the chore, there was a class defection," 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 forestall 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 activity – and he's never attempted information technology once more. "That was 2009, and now with mobile every bit present every bit it is, I don't even know what students would do if I asked them to do that," he says. "They'd probably report me to the university president."

But with our e'er-connected lifestyles, the question is now more relevant than e'er: what would happen if the internet stopped for a day? Information technology turns out the bear upon might not exist quite what y'all'd wait.

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

According to the Pew Inquiry Centre, a fifth of all Americans say they use the internet "almost constantly" and 73% say they use information technology at least daily. Figures in the UK are like: a 2016 survey found that nearly 90% of adults said they had used the internet in the previous three months. For many, it is now virtually impossible to imagine life without the internet.

"I of the biggest problems with the internet today is that people take it for granted – nevertheless they don't sympathise 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 fifty-fifty call up almost not having access to information technology."

But the internet is non inviolable. In theory, it could be taken abroad, on a global or national calibration, for a stretch of fourth dimension. Cyberattacks are one possibility. Malicious hackers could bring the internet to a standstill past releasing software that aggressively targeted vulnerabilities in routers – the devices that forrad internet traffic. Shutting down domain proper name servers – the internet's address books – would as well cause massive disruption, preventing websites from loading, for case.

Cut the deep-sea cables that behave vast volumes of net traffic between continents would likewise cause significant disruptions by disconnecting one part of the world from another. These cables may non exist like shooting fish in a barrel targets for attackers, merely they are sometimes damaged accidentally. In 2008, people in the Middle East, Bharat and Southeast Asia were plagued past major internet outages on 3 separate occasions when submarine cables were cut or interfered with.

Some governments too have "kill switches" that can effectively turn off the internet in their country. Egypt did this during the Arab Spring uprising in 2011 to brand it more difficult for protesters to coordinate their activity. Turkey and Iran have also close off cyberspace connectivity during protests. Cathay is rumoured to accept a impale switch of its own. And American senators accept proposed creating one in the United states as a means to defend the land from cyberattack.

Edifice a kill switch is non like shooting fish in a barrel, however. The larger and more adult the country, the harder it is to close down the internet completely – there are but also many connections betwixt networks both within and outside national borders.

The almost devastating strikes could come from space, however. A large solar storm that sent flares in our direction would have out satellites, power grids and calculator systems. "What bombs and terrorism can't do might be accomplished in moments by a solar flare," says David Eagleman, a neuroscientist at Stanford Academy and writer of Why the Net Matters. "The next major geomagnetic storms are somewhen coming."

But most outages would non terminal long. "There's an army of people ready to put things correct," says Scott Borg at the United States Cyber Consequences Unit, a not-profit organisation. "The cyberspace service providers and the companies that make the routing equipment accept plans and personnel in place for getting things upward and running over again if unexpected vulnerabilities are exploited." We are then used to having an always-on internet connection that fifty-fifty relatively short disruptions would have an event, however. It just might non be what y'all would expect.

For a offset, the impact to the economic system may non be too severe. In 2008, the US Section of Homeland Security asked Borg to wait into what might happen if the net went downwards. Borg and his colleagues analysed the economic effects of computer and cyberspace outages in the United states from 2000 onwards. Looking at quarterly fiscal reports from the twenty companies that claimed to be most affected in each case, as well as more than general economical statistics, they discovered that the financial affect of an outage was surprisingly insignificant – at least for outages that lasted no more than iv 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. "Only while some industries similar hotels, airlines and brokerage firms suffered a chip, even they didn't feel very big losses."

It turned out that losing internet admission for a few days merely made people fall behind on their work. "People carried out all the same activities they would have done had the net been upwards, but they just did information technology ii or 3 days later," Borg says. "The economic system is set up to bargain with what essentially amounts to a holiday weekend."

In some cases, shutting down the internet for a short time might even increase productivity. In another study, Borg and his colleagues analysed what happened when a company suffered an net outage that lasted four hours or more. Rather than twiddle their thumbs, employees did things that they would normally put off, such as dealing with paperwork. The result was a boost for business. "We jokingly suggested that if every visitor turned off their computers for a few hours each calendar month and made people exercise the tasks they postponed, there'd be an overall productivity benefit," Borg says. "I come across no reason why that wouldn't also apply to basically the whole economic system."

Travel probably would not be affected besides much in the short term, either – and then long equally the blackout lasted no more than a day or so. Planes can wing without the net, and trains and buses would continue to run. Longer outages would commencement to accept an effect on logistics, however. Without the cyberspace it would exist hard for businesses to operate. "I've suggested that people and businesses should have a plan in place in the event of internet loss, but I oasis't heard of anyone doing that yet," Eagleman says.

A large advice breakdown would probably disproportionately impact small businesses and blue-neckband workers. In 1998, as many every bit 90% of the 50 million pagers in the US stopped working because of a satellite failure. In the days following the blackout, Dutton surveyed 250 pager users in Los Angeles and found articulate socioeconomic divisions in people's reactions to being cut off. Upper-middle-class individuals with managerial or professional jobs did not perceive the event as largely problematic. "To them, information technology felt like a snow day," Dutton says. "It was a relief."

Just 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 also reported significant distress at not existence able to be paged if a problem occurred. "Then you lot have to realise that your reaction to the idea of losing the internet is likely to exist based on your socioeconomic condition," Dutton says.

Psychological effects, similar feelings of isolation and feet, would striking people beyond the lath, notwithstanding. "Almost of the internet is designed for i purpose: to let usa to communicate with each other," Hancock says. We are used to being able to connect to anyone, anywhere and at whatsoever time. "An inability to practise that would exist unsettling." Information technology'southward a feeling Borg recognises too. "I know when I realise I've left my smartphone behind, I feel slightly naked," he says. "I of a sudden have to retrieve, 'Exercise I actually know where I'g going? What if my car breaks down, could I talk anyone into letting me use their phone to call for aid?'"

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

"In that location'south this idea that mayhap people would become more social and more in touch on with friends and family if they didn't have use of the internet, but I think that's really mistaken," Dutton says. "Most people using the internet are actually more than social than those who are non using the internet."

Stine Lomborg at the University of Copenhagen agrees. "It's non like we'd exist more probable to speak to strangers at the bus stop if we didn't accept our smartphones – not at all," she says. The loss of connection may brand people more social in specific situations, such as 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 autumn apart if we didn't accept access to the internet for a day," she says. "But for most people I call up fifty-fifty one day without information technology would be terrifying."

The feeling would exist fleeting, however. Losing the internet may brand people recognise its importance in their lives, just we would soon be taking information technology for granted once more, says Hancock. "I'd like to say an net blackout would crusade a shift in our thinking, simply I don't call back it would." Fifty-fifty so, that'southward still non enough to persuade his students to requite it up for a weekend.
