The internet, also known as the World Wide Web, is a fragile worldwide physical and digital network that is easily paralyzed
Why is that, and how can its defenses be strengthened?
What problem does the internet have?
Every day, the great majority of people on the planet depend on the internet for social, professional, and financial purposes. However, because of the network's widespread use, its frequent failures and outages as well as its susceptibility to malicious actors' attacks are becoming increasingly concerning. A small technical issue at an Amazon facility in Virginia caused Instagram, Hulu, Snapchat, Reddit, and ChatGPT to go down in October. Millions of internet-connected gadgets, such as sophisticated temperature-changing mattresses and smart speakers, broke down. However, that was quite insignificant. Approximately 8.5 million computers abruptly crashed globally in July 2024, causing businesses to struggle and displaying blue screens. A bug in a regular software update was the cause of the outage, which was connected to Microsoft's security vendor CrowdStrike.
Why is it that the internet is so unstable?
Because underneath the shiny gigabit-broadband exterior is a patchwork of deteriorating infrastructure, fragile protocols, concentrated corporate control, and geopolitical tensions that frequently strain the worldwide network. A portion of this fragility can be attributed to the internet's early ad hoc growth and cooperative spirit of amateurism, as well as its subsequent development. Because there are so many operational componentsboth digital and physicalit is vulnerable. The internet is supported by an enormous worldwide network of intricate physical infrastructure, ranging from massive server farms in Virginia managed by Amazon Web Services (AWS) to undersea cables that circle the globe.
Are the cables beneath the ocean safe?
Over 95% of the world's data is transmitted via approximately 550 fiber-optic cables that are buried beneath the ocean. However, far from being futuristic, these cables are extremely susceptible to commonplace dangers like ship anchors, fishing trawlers, earthquakes, landslides, and sabotage by hostile state actors. It can take days or even weeks for specialized ships to make repairs. The corporate behemoths protect their assets, of course. However, in October, technical problems at Amazon's Virginia facilities caused a brief internet outage for people worldwide.
Internet-based exchanges.
Internet Exchange Points (IXPs), warehouse-sized facilities where networks connect and manage enormous volumes of domestic and international traffic, are the foundation of the internet at a more local level. There are thousands of them in the world, but only a small percentage manage a disproportionate amount of the world's traffic, making them crucial single points of failure. Large portions of the global internet may vanish along with an IXP in the event of a fire, power outage, or cyberattack.
What is the digital architecture of the internet?
Because the internet is a complex networkin fact, a network of networks made up of millions of nodesit is intrinsically fragile and can have enormous worldwide effects from very small causes. Every message sent passes through a maze of cables, servers, routers, and occasionally satellites. The same gateways, load balancers, identity checkpoints, and routing layers are utilized by numerous digital services. A DNS pointer inside AWS disappearing, a Google service-control routing rule drifting, or a Cloudflare configuration file expanding beyond its limit are just a few examples of minor errors that can cause entire systems to go awry with far-reaching effects. However, the protocols that keep the internet operational would make it vulnerable even if the physical network were perfect and the digital architecture was unbreakable.
The way internet protocols operate.
The Border Gateway Protocol (BGP), which routes traffic between networks but was never intended with security in mind, is the most fundamental or infamous. Traffic can spiral into hostile servers or black holes after a single incorrect update or malicious reroute. In the meantime, although technically decentralized, the Domain Name System (DNS), the internet address book with its well-known suffixes, is actually highly dependent on a small number of powerful operators.
Even if the websites themselves are in perfect condition, users may find themselves unable to access significant portions of the web if one of these is compromised or fails. These vulnerabilities are not system flaws; rather, they are relics from the early 1990s, when the internet was a mass-user network in a less connected and more trusting time. According to The Economist, people who maintain the open-source code that powers the internet still frequently do so in their free time.
Does a cloud increase resilience?
Yes, no. According to Will Gottsegen in The Atlantic, the expansion of the cloud, spearheaded by Amazon, has increased the internet's vulnerability and centralized its control. In the past, creating a website required purchasing physical servers, obtaining software licenses, and writing the basic code from scratch. These days, AWS and a few others own the servers and pre-write the code for a monthly fee. As the servers "are consolidated under a handful of companies," so too are the possible weak points.
What can we do to improve the internet?
Redesigning crucial protocols like BGP with built-in authentication; diversifying physical infrastructure, such as more international cable routes and more regionally dispersed IXPs; implementing multi-cloud strategies to prevent organizations from being dependent on a single provider; incorporating far more security into internet-dependent consumer products; utilizing regulation to encourage greater diversity of suppliers in web services; and creating international norms, modeled on the rules of warfare, that forbid targeting civilian infrastructure in cyberspace. It is not necessary for the internet to be this vulnerable. However, we must first acknowledge its actual fragility.
