Understanding the Relationship Between BGP and Facebook's Disappearance from the Internet, and the Impact of IPOs in 2020

In today's interconnected world, the Internet plays a vital role in our daily lives. We rely on it for communication, information, and even entertainment. But have you ever wondered how the Internet actually works? One crucial component that ensures the smooth functioning of the Internet is the Border Gateway Protocol (BGP). BGP acts as a mechanism for exchanging routing information between different networks, known as autonomous systems (AS).

To put it simply, BGP allows networks to communicate with each other and share information about the routes they can take to reach specific destinations. Without BGP, the Internet routers wouldn't know where to send data packets, and the Internet as we know it would cease to function.

Now, let's take a closer look at the recent incident where Facebook mysteriously disappeared from the Internet. It was as if someone had unplugged Facebook's data centers from the rest of the world. The root cause of this disappearance was the withdrawal of route announcements by Facebook through BGP. When Facebook stopped advertising its presence to other networks, it effectively disconnected itself from the Internet.

Every network, including Facebook, has an Autonomous System Number (ASN). An ASN represents an individual network with its own internal routing policies. For Facebook to remain connected to the Internet, it needs to announce its prefix routes (the IP address ranges it controls) to other networks using BGP. By doing so, other networks can establish connections with Facebook and know how to find its servers.

On a specific day, at 1658 UTC, it was noticed that Facebook had stopped announcing the routes to their DNS prefixes. This meant that Facebook's DNS servers, which are responsible for translating domain names into IP addresses, became unavailable. As a result, both Facebook and its associated sites went offline, leaving millions of users unable to access their services.

The incident highlighted the critical role BGP plays in maintaining the integrity of the Internet. It serves as the glue that holds the network of networks together, ensuring seamless connectivity and communication. Without BGP, the Internet would be fragmented, and accessing different websites or services would become nearly impossible.

Switching gears, let's delve into the world of Initial Public Offerings (IPOs) and their impact on the financial markets. In 2020, despite the challenges posed by the COVID-19 pandemic, the IPO market witnessed significant activity. Many companies went public, aiming to raise capital and expand their operations. However, the success of an IPO is often measured by the "pop" it experiences on the first day of trading.

The term "pop" refers to the percentage increase in a company's stock price on its first day of trading compared to its IPO price. Surprisingly, only 25% of companies ended the day with a lower stock price than their IPO price. In contrast, more than 25% of companies experienced a pop of over 50%, indicating strong investor demand.

For the 61 IPOs that took place in the US in 2020, the median company experienced a pop of 20% on its first day of trading. This means that, on average, investors were willing to pay 20% more than the IPO price for the newly listed companies. While this may seem like a positive outcome for the companies going public, it raises questions about the efficiency of the IPO pricing process.

The discrepancy between the IPO price and the market valuation of a company at the time of listing can have significant implications. In the case of the 61 IPOs in 2020, it was estimated that these companies raised $6.7 billion less than they could have if their IPO prices had aligned with the market's valuation. This shortfall in capital can limit the company's ability to invest in growth opportunities and hinder its long-term prospects.

Institutional investors, such as mutual funds and pension funds, play a crucial role in the IPO process. These investors typically receive allocations of shares at the IPO price and aim to make a return on their investment. Therefore, their incentive is to acquire the stock at the lowest possible price. This misalignment of interests between the company going public and the institutional investors can lead to pricing inefficiencies and potential losses for the company.

So, what can be done to address these issues and ensure a fair and efficient IPO process? Here are three actionable pieces of advice:

1. Improve Pricing Mechanisms: IPO pricing can be a complex and opaque process. Implementing more transparent and data-driven methods for determining the IPO price can help reduce the gap between the market valuation and the IPO price. This can result in companies raising the capital they need to fuel their growth.

2. Align Incentives: Encouraging institutional investors to have a long-term perspective and align their interests with the company's goals can lead to better pricing outcomes. This can be achieved by introducing lock-up periods, where investors are restricted from selling their shares immediately after the IPO, incentivizing them to support the company's long-term success.

3. Educate Companies: Many companies going public may not fully understand the intricacies of the IPO process and the potential implications of mispricing. Providing educational resources and guidance to these companies can empower them to make informed decisions and negotiate fair terms during the IPO process.

In conclusion, the incident involving Facebook's disappearance from the Internet serves as a stark reminder of the importance of BGP in maintaining the connectivity of the global network. Understanding how BGP works and its role in enabling communication between networks is crucial for ensuring a reliable and functional Internet.

On the other hand, the impact of IPOs in 2020 highlights the need for improvements in the pricing mechanisms and alignment of incentives to ensure fair and efficient capital raising for companies going public. By addressing these issues, we can create an IPO process that benefits both the companies and the investors, fostering long-term growth and economic prosperity.
