The Next Solar ‘Superstorm’ Could Shut U.S. Internet for Several Months, Research Says

Months into the pandemic, an old video resurfaced on the mainstream internet. 

A TED talk, its host Bill Gates, presented a cogent argument for why the biggest threat to the world is not a nuclear war, but a viral outbreak. Instead of investing billions in the military and arsenal expansion, Gates argued that we must invest in healthcare, strengthening its infrastructure to prepare for and mitigate, even, the next global catastrophe. 

In the future, “not missiles, but microbes” would be responsible for millions of deaths, warned Gates. And it has turned out to be the most poignant, and deadly, “I told you so” in recent history.

To make it right, we can only ensure that we avoid making such a grave mistake again in the future.  

And we already have an opportunity to do just that.  

According to new research presented at the SIGCOMM 2021 data communication conference, the current internet infrastructure is vulnerable to solar superstorms. Exposure to intense solar emissions could disrupt the global internet, disconnecting entire countries from the network for several months. 

If the internet is a basic human right, if it directly or indirectly affects every single day of our lives, we must surely strengthen its infrastructure to prepare for — mitigate, even — the disruption. 

A solar, what?

Every 11 years or so, the Sun completes a solar cycle. The cycle sees the Sun emit what are called solar flares, as its magnetic field gradually evolves. 

Solar flares are outbursts of charged particles from the Sun. It’s the charged particles that are responsible for the Northern and Southern Lights. The stunning display of lights is the result of their interaction with the Earth’s magnetic field at its poles. 

An aurora, also known as northern lights or southern lights.

The Sun also emits what are called Coronal Mass Ejections (CMEs). For the layman, CMEs are solar flares, but more explosive. So explosive, in fact, that they can knock out entire power grids. Indeed, they did, in 1989, when a moderate solar storm took down the Hydro-Quebec grid, leading to a 9-hour blackout (Scientific American). 

Although, the emissions become more frequent and intense at the cycle’s peak, called the solar maxima. They are still rare, but less rare than they ordinarily are. 

Why is this a problem now? Because the next peak — likely to be in the mid-2020s — is estimated to be the most intense since we began keeping records (National Geographic). 

What the research argues is that if the unlikely event does occur, the current infrastructure would not be able to cope with its effects. Especially, North America. 

‘Planning for an internet apocalypse’

The research, titled “Solar Superstorms: Planning for an Internet Apocalypse,” was presented by Sangeetha Abdu Jyothi, Assistant Professor, UC Irvine. It examined the effect of CMEs on the global internet.

CMEs, like a pandemic, are rare, but devastating. And while power grids are equipped to deal with the electromagnetic disturbance, the global internet framework is not, the research says.

If the fiber optics linking the cities are the pipelines within a household, the subsea cable linking two continents is the main water supply. According to the research, while the grounded fiber optics are relatively safe from solar superstorms, subsea cables, “the invisible backbone of the internet”, are not. 

Why? Because at an interval of 50-150 kilometers, subsea cables are attached with amplifiers that repeat or boost the signal to prevent it from dying as it travels over long distances. The amplifiers are vulnerable to sudden electromagnetic disturbances, like those induced by CMEs, putting the cables, and therefore, the global internet at risk.

The research cites particular caution to the US, which is closer to the poles, where the effects are most intensely felt.  

And that’s what puts the entire network at risk.  

Even though Asia, situated near the equator, would be less exposed, an internet outage in the US — for several months, at that — could seriously destabilize the world economy. In the US alone, an outage could lead to over $7 billion in losses per day (Forbes).

Even satellites are vulnerable. In fact, the research claims that satellites are the most vulnerable, as the barrage of particles could damage key components and even send them hurling toward the Earth. Starlink, a SpaceX initiative, will soon supply low-cost broadband to areas which the internet has found harder to penetrate. Is SpaceX prepared?

Even satellites are vulnerable.

The research is a wake-up call for both public and private institutions worldwide. Like our infrastructure for healthcare, our infrastructure for communication has also been overlooked. The very infrastructure that is the nervous system of modern work, education, entertainment, commerce, activism, and whatever connects us and our ideas. 

It’s high time we learn from our mistakes.
