No one could have predicted what we have just gone through with COVID 19, lock downs, State of Emergency, banning of international travel etc. Infact that’s not quite true as many had been predicating the possibility of a global pandemic for a while - I guess it was the case of not listening or not wanting to listen.
This week I was left thinking what life would be like if the internet crashed. This was prompted after being deprived of social media when the services of Facebook, Instagram & WhatsApp were disrupted for hours on Monday night. I am not much of a user of the 2 former platforms but I do use Whatsapp extensively and even had a call scheduled on the app which I was clearly unable to make. It is also the main way that I keep immediately updated of family whereabouts, comms etc. Like many I felt quite cut off even though I could have made a normal telephone call or gone on the internet and sent mail messages. People kept saying that the internet was down because to some people Facebook is the internet! Twitter, realising this, saw it as the perfect time to enjoy its rare spotlight and tweeted “Hello literally everyone” from its main account. It garnered 2.4 million “likes” in just four hours and a stampede of users eager to sign up.
In other parts of the world where apps are essential to commerce, health care and basic functioning of government it was a serious matter. In India, doctors sounded the alarm about being unable to coordinate their schedules or share patient scans. And in Malaysia, some small-business owners were left without a way to manage day-to-day operations as all business communications are conducted through the app. In many developing countries, services including WhatsApp, Facebook and Facebook Messenger have become deeply integrated into the delivery of primary health care, education and other government services,” Marcus Leaning, a digital media education professor at the University of Winchester in the U.K., said. “In the global North, we tend to (merely) use such services as supplementary to other channels of communication, so the global outage will have a disproportionate impact.” These platforms are also often offered on restricted-access (or non-smart) phones, meaning that those on lower income were disproportionately disaffected in 3rd World countries, our own included.
Meanwhile, as netizens (citizens of the internet) were feeling somewhat inconvenienced and annoyed, Facebook CEO Mark Zuckerberg took a financial hit losing $6 billion in just a few hours as Facebook stocks plunged, principally through lost advertising revenue and loss of business confidence and he himself personally dropped to No. 5 on the list of the world’s richest, below Gates. Talk about a bad day at the office!
The impact on myself was considerably less but with my ability to WhatsApp stopped I did feel quite put out and wondered what it would be like if the whole internet crashed one day and what that would it do to the markets, the military, the hospitals, not to mention how would I be able access all the movies on Netflix?
It couldn’t really happen, could it, if you understand that all the internet is, is a bunch of interconnected computers and that they would all have to crash at once? Conventional wisdom tells us that as a planetary network of computers and machines the internet is too big, too decentralised and too redundant to all fail at once? But wait! Didn’t they say something similar when the Titanic was built? Surely the lessons of that hubris are still valid today?
According to Laura Brandimarte, Assistant Professor, Management Information Systems, University of Arizona, ‘Everything being connected today may bring along significant convenience, but it also implies that everything can be hacked. What if the nation’s power grid were successfully attacked? No electricity also means no internet access. The internet also relies on physical infrastructure, such as subsea cables and other fibre cables: any infrastructure issues (cable cuts, damages), whether due to criminal activity or natural disasters that were to affect major subsea cables could potentially shut down the Internet.
In a different sense, authoritarian governments can also potentially shut down the internet if they somehow all colluded against it, either blocking internet access to citizens altogether (we have seen that in Egypt during the Arab Spring, for example, or in the Democratic Republic of the Congo during a period of unrest); or substantially limiting it (we see that in countries where internet censorship is widespread and information access is controlled by the central government, as it happens in China). There are ways around censorship, of course: Privacy Enhancing Technologies, or PETs, such as virtual private networks or VPNs, and anonymous browsers such as Tor, can help circumvent it, but censorship essentially prevents the vast majority of the population, who may not be familiar with these tools, to access the internet, de facto making it disappear.
And there are natural disasters that also could create havoc. Patrick Juola, a computer science professor at Duquesne University, offers up one such interplanetary electronic disaster. “A sufficiently powerful solar flare could produce an electromagnetic solar pulse [EMP] that would shut down most of the computers in the world. While some systems are protected against EMPs, any human-built protection is only so strong, and the sun can be a lot more powerful.”
An internet crash resulting from this type of solar flare sounds like science fiction or one of those once-every-10,000-years events, but it isn’t. The worst recorded X-class (highest level) solar flare, called the Carrington Event, was a coronal mass ejection that produced a geomagnetic storm that spread across the earth over two days, September 1-2, 1859. The storm produced auroras around the world. The ones in the northern hemisphere reached as far south as the Caribbean, and were so bright people in the north-eastern United States could read newspapers by their light at night. The major electric utilities affected were the telegraph systems that failed across Europe and North America. The telegraph pylons threw sparks and shocked operators still at their keys.
The frequency of recorded CMEs is worrying. Less powerful geomagnetic storms were recorded in 1921 and 1960, and a 1989 storm disabled power over large sections of Quebec. Then, on July 23, 2012, a “Carrington-lass” solar superstorm narrowly missed the earth by nine days when it crossed the planet’s orbit.
The Titanic was built to be unsinkable - all engineers and scientists agreed to that. Yet obviously they had not thought of every conceivable scenario and so when the boat was in the wrong place at the wrong time, the rest, as they say, was history. The same must be true of the internet. The thing that can take it down – not so much governmental censorship but some of that super global warming we hear so much about - could yet prove its downfall. Now that really is solar power!
