问题 In 2008，the US Department of Homeland Security asked Borg to look into what might happen if the internet went down．Borg and his colleagues analyzed the economic effects of computer and internet outages in the US from 2000 on wards．Looking at quarterly financial reports from the 20 companies that claimed to be most 46 in each case，as well as more general economic statistics，they discovered that the financial impact of an outage was surprisingly insignificant--at least for outages that lasted no more than four days，which is all they studied．
    “These were instances where enormous 47 were being claimed in the hundreds of millions and even billions of dollars，”Borg says．“But while some industries like hotels，air lines and brokerage firms suffered a bit，even they didn’t48very big losses．”It turned out that losing internet access for a few days just made people49on their work．“People carried out all the same activities they would have done had the internet been up，but they just did it two or three days later，”Borg says．“The economy is set up to deal with what 50amounts to a holiday weekend．”
In some cases，shutting down the internet for a short time might even 51 productivity．In another study，Borg and his colleagues analyzed what happened when a company suffered an internet outage that lasted four hours or more．Rather than twiddle their thumbs，employees did things that they would normally 52，such as dealing with paperwork．The result was a boost for53．“We jokingly suggested that if every company 54 their computers for a few hours each month and made people do the tasks they postponed，there would be an overall productivity benefit．”Borg says．  “I see no reason why that wouldn’t also apply to basically the who lee economy．”Travel probably would not be affected too much55，either so long as the blackout lasted no more than a day or so．Planes can fly without the internet，and trains and buses would continue to run．Longer outages would start to have an effect on logistics，however．Without the internet it would be 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 haven’t heard of anyone doing that yet，”Eagle man says.
