Understanding How Facebook Disappeared from the Internet: The Role of BGP and the Four Kinds of Luck

In today's interconnected world, the Internet plays a crucial role in our daily lives. We rely on it for communication, information, and entertainment. But have you ever wondered what would happen if a major website like Facebook suddenly disappeared from the Internet? How could such a massive platform simply vanish? The answer lies in the intricate workings of the Border Gateway Protocol (BGP) and the concept of luck.

BGP, or Border Gateway Protocol, serves as the backbone of the Internet. It allows for the exchange of routing information between different autonomous systems (AS) that make up the Internet. Without BGP, the Internet routers would be clueless about where to send data, and the Internet would cease to function.

In the case of Facebook's disappearance, it was as if someone had "pulled the cables" from their data centers all at once and disconnected them from the Internet. The Internet is essentially a network of networks, and BGP is what keeps it all together. It enables one network, like Facebook, to advertise its presence to other networks, allowing for seamless connectivity.

Every network has its own Autonomous System Number (ASN), which represents an individual network with a unified internal routing policy. To establish connectivity with the rest of the Internet, every ASN must announce its prefix routes using BGP. This ensures that other networks know how to connect and where to find them.

On a particular day, at 1658 UTC, it was noticed that Facebook had stopped announcing the routes to their DNS prefixes. This meant that at least Facebook's DNS servers were no longer accessible. As a result, Facebook and its associated sites effectively disconnected themselves from the Internet. The routes were withdrawn, and Facebook's DNS servers went offline. This sudden change meant that DNS resolvers, including ours and others', had no way to connect to Facebook's nameservers.

Now, let's shift gears and explore the concept of luck, as introduced by Dr. James Austin in his book "Chase, Chance, and Creativity." Luck, according to Dr. Austin, can be categorized into four types: Chance I, Chance II, Chance III, and Chance IV.

Chance I is purely accidental luck, something that happens without any effort on our part. It is blind luck that comes unexpectedly. On the other hand, Chance II involves taking action and stirring things up. By actively engaging and exploring different ideas and possibilities, we increase the likelihood of chance occurrences. This type of luck is often associated with individuals who persistently pursue curiosity and embrace experimentation.

Chance III goes beyond mere action and requires a special receptivity and intuitive grasp of significance. It is a unique kind of luck that favors those who possess a sufficient background of knowledge, observation skills, and the ability to form new associations quickly. This type of luck is highly personalized and often only recognizable to the individual who possesses it.

Finally, Chance IV is the kind of luck that arises from probing actions with a distinctive personal touch. It is intimately tied to who you are and how you behave. This kind of luck is not easily understood by others on the first encounter. Chance IV is closely related to our sensory receptivity and motor behavior, making it highly individualized.

When it comes to problem-solving and innovation, curious individuals have an advantage. Their inquisitive nature and willingness to explore a wide range of topics provide them with a diverse pool of knowledge and experiences. Curiosity allows them to connect seemingly unrelated ideas and come up with unique solutions. In contrast, individuals who rely solely on logic and intellectual effort may struggle to find creative solutions.

In conclusion, the sudden disappearance of Facebook from the Internet can be attributed to the withdrawal of their route announcements through BGP. This incident highlights the critical role BGP plays in maintaining connectivity between networks. Additionally, the concept of luck, as described by Dr. James Austin, offers insights into the different types of luck that can influence our lives. By embracing curiosity and staying open to chance occurrences, we can increase our chances of stumbling upon unique opportunities.

Before we wrap up, here are three actionable pieces of advice:

1. Stay informed about the infrastructure that powers the Internet. Understanding the basics of BGP and how it enables connectivity between networks can help you navigate the digital landscape more effectively.

2. Cultivate curiosity and embrace experimentation. By actively seeking out new experiences and exploring diverse subjects, you increase the likelihood of chance encounters and serendipitous discoveries.

3. Be open to unexpected opportunities. Sometimes, the most significant breakthroughs come from seemingly insignificant moments. Stay receptive to the unexpected and be willing to explore uncharted territories.

Remember, luck isn't just a matter of chance; it can be influenced by our actions and mindset. By harnessing the power of BGP and embracing the different types of luck, we can navigate the ever-changing digital landscape with confidence and seize opportunities that come our way.
