Understanding How Facebook Disappeared from the Internet: The Importance of BGP and the Disconnect

In the age of the Internet, it is hard to imagine a world without our beloved social media platforms. But what happens when one of these platforms suddenly vanishes from the Internet? This is exactly what happened to Facebook, leaving millions of users puzzled and disconnected. To understand this phenomenon, we need to delve into the world of Border Gateway Protocol (BGP) and the crucial role it plays in keeping the Internet functioning.

BGP, or Border Gateway Protocol, serves as a mechanism for exchanging routing information between autonomous systems (AS) on the Internet. It acts as the glue that holds the Internet together, ensuring that routers know where to send data packets. Without BGP, the Internet would be in chaos, with routers clueless about where to direct traffic.

To grasp the gravity of Facebook's disappearance, we must comprehend the concept of autonomous systems. An autonomous system is an individual network with a unified internal routing policy. Each of these networks has its own Autonomous System Number (ASN). For example, Facebook is an autonomous system with its own ASN. These ASNs need to announce their prefix routes to the Internet using BGP. Failure to do so would result in no one knowing how to connect to their network.

On a seemingly normal day, at 1658 UTC, Facebook ceased to announce the routes to their DNS prefixes. DNS stands for Domain Name System, and it is responsible for translating human-readable domain names into IP addresses. In simpler terms, it is what allows us to access websites by typing in their names rather than a series of numbers. The withdrawal of these routes meant that Facebook's DNS servers were effectively offline. With their DNS servers inaccessible, Facebook and all associated sites disconnected themselves from the Internet. It was as if someone had pulled the cables from their data centers all at once.

Interestingly, this unexpected event sheds light on a fascinating trend in today's digital landscape. Many people share articles online without actually reading them in their entirety. Research shows that there is a weak correlation between scroll depth and sharing. Only a small fraction of readers make it to the end of an article, and the more content there is, the more people tune out.

Schwartz's data on tweeting habits reveal that individuals often share articles they haven't fully read. So, when you come across someone recommending a story online, it is wise not to assume that they have read it thoroughly. This revelation brings a humorous twist to our understanding of online behavior. Perhaps the person sharing the article about Facebook's disappearance didn't actually read the entire article themselves.

It is important to note that articles that generate a high number of tweets are not necessarily the ones that are read deeply. This suggests that the act of sharing is often driven by factors other than the content itself. It could be the headline, a catchy quote, or simply the desire to appear informed. This phenomenon highlights the complexities of human behavior in the digital age.

So, what can we learn from Facebook's sudden disappearance and the revelation about sharing habits? Here are three actionable pieces of advice to consider:

1. Verify before sharing: Before sharing an article or news story, take a moment to verify the information yourself. Don't rely solely on the recommendations of others. By doing so, you can help combat the spread of misinformation.

2. Engage with content: Instead of mindlessly scrolling and sharing, make a conscious effort to engage with the content you come across. Read articles thoroughly, leave comments, and contribute to meaningful discussions. This not only enhances your understanding but also promotes a more informed online community.

3. Be aware of your online presence: Recognize that what you share online reflects your interests, values, and level of knowledge. Take pride in being a discerning consumer of information and strive to share content that you have genuinely engaged with.

In conclusion, Facebook's disappearance from the Internet serves as a stark reminder of the critical role BGP plays in keeping our online world connected. It also highlights the fascinating disconnect between scrolling habits and sharing behavior. By being mindful of our online actions and engaging with content in a meaningful way, we can contribute to a more informed and connected digital society. So, the next time you stumble upon an article, make a conscious effort to read it fully before hitting that share button.
