Understanding How Facebook Disappeared from the Internet: The Role of BGP and Autonomous Systems

In today's interconnected world, the Internet plays a vital role in keeping us connected and informed. But have you ever wondered what happens when a giant like Facebook suddenly disappears from the Internet? How is it possible for such a prominent platform to go offline? The answer lies in the intricate workings of the Border Gateway Protocol (BGP) and Autonomous Systems (AS).

BGP, or Border Gateway Protocol, is a mechanism that allows different autonomous systems (AS) on the Internet to exchange routing information. It acts as the backbone of the Internet, ensuring that routers know where to send data packets. Without BGP, the Internet simply wouldn't work.

The Internet, as we know it, is a network of networks. Each network is represented by an Autonomous System Number (ASN), which identifies an individual network with its own internal routing policy. To connect with other networks and effectively announce their presence, every ASN needs to use BGP to advertise its prefix routes to the Internet.

Let's take Facebook as an example. Facebook is a massive network with its own ASN. Through BGP, Facebook advertises its presence to other networks, allowing them to know where to find it and how to connect. However, on a fateful day, the routing information for Facebook mysteriously disappeared.

On a closer look, it became evident that Facebook had stopped announcing the routes to their DNS (Domain Name System) prefixes. This meant that their DNS servers were no longer accessible. In other words, Facebook had effectively disconnected itself from the Internet.

To put it simply, it was as if someone had "pulled the cables" from Facebook's data centers, disconnecting them from the rest of the online world. Without the routing information provided by BGP, Facebook's DNS servers went offline, rendering their services inaccessible.

This incident highlights the critical role that BGP and AS play in keeping the Internet functioning. The interconnectivity of networks through BGP ensures that data packets reach their intended destinations. When a network like Facebook disconnects itself from the Internet by withdrawing its routes, it effectively isolates itself from the rest of the online community.

Now, let's shift our focus to the world of cryptocurrencies and explore the concept of cap tables. Cap tables, short for capitalization tables, are commonly used in the world of finance to outline the ownership structure of a company.

In the context of crypto companies, there are two types of cap tables that play a crucial role: the equity cap table and the token cap table. The equity cap table determines the ownership of the company, while the token cap table outlines the ownership of tokens.

In the case of crypto companies, the token cap table often dominates the equity cap table. This is because tokens are used to incentivize network participants, such as validators and stakers, to jumpstart network effects. These community tokens are distributed pro-rata across the token cap table, ensuring that the community has a significant stake in the network.

However, there is an additional element in crypto cap tables that is not found in traditional equity cap tables: the treasury. The treasury captures tokens from the foundation's efforts to participate in the community, such as running validators or stakers. This treasury serves as a mechanism for the foundation to support and contribute to the growth of the network.

It's important to note that crypto deals are often unique and tailored to the specific needs of the company. Investor token ownership rights can take various forms, such as warrants, which give equity investors the right, but not the obligation, to purchase tokens at a discounted price in an early round.

In conclusion, the disappearance of Facebook from the Internet serves as a reminder of the critical role played by BGP and Autonomous Systems in keeping the online world connected. The incident highlights the vulnerability of even the largest networks and the importance of maintaining a robust infrastructure.

Additionally, the concept of cap tables in the crypto world sheds light on the unique ownership structures and incentives that drive these networks. The dominance of the token cap table and the inclusion of a treasury reflect the evolving nature of finance and the integration of blockchain technology.

To navigate this ever-changing landscape, here are three actionable pieces of advice:

1. Invest in a resilient infrastructure: Whether you're a large corporation or a small startup, ensuring that your network is well-connected and has a robust BGP implementation is crucial. Regularly monitor and maintain your routing information to avoid any unexpected disconnects.

2. Understand the nuances of crypto cap tables: If you're considering investing in a crypto company or participating in a token sale, take the time to understand the ownership structure outlined in the token cap table. Be aware of any unique elements, such as the treasury, and evaluate how they align with the company's goals and community incentives.

3. Stay informed about the latest developments: The world of technology and finance is constantly evolving. Stay updated on the latest trends and insights to make informed decisions. Follow industry experts, read reputable publications, and engage with the community to stay ahead of the curve.

By understanding the intricacies of BGP, AS, and cap tables, we can gain a deeper appreciation for the complex web that keeps us connected online. Whether it's the sudden disappearance of a giant like Facebook or the innovative structures of crypto networks, these concepts shape the way we experience and participate in the digital world.
