Understanding How Facebook Disappeared from the Internet: The Impact of BGP

The Internet, a vast network of networks, relies on the Border Gateway Protocol (BGP) to exchange routing information between autonomous systems (AS) and keep everything connected. Without BGP, Internet routers would be lost, and the Internet would cease to function. It is through BGP that networks like Facebook can advertise their presence to others and ensure connectivity.

Every network has an Autonomous System Number (ASN), which represents an individual network with a unified internal routing policy. For example, Facebook has its own ASN. To maintain connectivity, every ASN needs to announce its prefix routes to the Internet using BGP. This allows other networks to know how to connect and find them.

However, on a fateful day, Facebook's routes were no longer being announced through BGP. This meant that their DNS servers, responsible for mapping domain names to IP addresses, became unavailable. With the withdrawal of routes, Facebook effectively disconnected itself from the Internet. Not only were users unable to access Facebook's services, but DNS resolvers across the Internet had no way to connect to their nameservers.

The incident highlights the critical role BGP plays in keeping the Internet functioning. It is the backbone that holds the network of networks together. Without proper BGP announcements, even the largest and most influential companies can disappear from the Internet.

The Double Diamond Design Model: A Framework for Success

The Double Diamond design model, conceived by the British Design Council in 2005, provides a structured approach to the design process. It consists of four stages: Discovery, Definition, Development, and Delivery.

During the Discovery stage, designers engage in activities such as mind mapping, brainstorming, desk research, and field research to gather insights and understand the problem at hand. This stage emphasizes the importance of immersing designers in the research process and bringing them face-to-face with users. By experiencing the user's perspective firsthand, designers can gain valuable insights that inform the subsequent stages.

The Definition stage is where the ideas and data gathered during Discovery are filtered and refined. It sets the context for product development, assesses the feasibility of the project, and ensures alignment with the corporate brand. This stage acts as a bridge between problem development and solution development, narrowing down the focus and allowing for a more targeted approach.

Development and Delivery, the final stages of the Double Diamond model, involve transforming the defined solution into a tangible product or service. By involving different departments and stakeholders throughout the design process, organizations can ensure fewer prototypes are needed and minimize issues discovered during testing. This collaborative approach enhances efficiency and reduces the time and resources required for product development.

Companies like Starbucks and Microsoft exemplify the effectiveness of the Double Diamond model. Starbucks mandates that designers spend time working as baristas before designing anything, immersing themselves in the customer experience. Microsoft encourages designers to "eat their own dog food," meaning they should use their own creations to better understand the user's perspective.

To implement the Double Diamond model successfully, it is essential to have a professional design tool that allows for quick and efficient changes. Designers need a tool that enables them to iterate and iterate rapidly, ensuring that the final product meets user needs and expectations.

Actionable Advice:

1. Embrace BGP: For companies reliant on the Internet, understanding and leveraging BGP is crucial. Ensure that your network is properly announcing routes through BGP to maintain connectivity and avoid disappearing from the Internet.

2. Implement User-Centric Design: Adopt the principles of the Double Diamond model to create products and services that truly meet user needs. Involve designers in the research process and encourage them to experience the user's perspective firsthand.

3. Foster Collaboration: Break down silos within your organization and involve different departments and stakeholders throughout the design process. This collaborative approach will lead to better outcomes, fewer prototypes, and smoother product development.

In conclusion, the disappearance of Facebook from the Internet due to BGP route withdrawals highlights the critical role BGP plays in maintaining connectivity. The Double Diamond design model, on the other hand, provides a structured approach to design, emphasizing user-centricity and collaboration. By understanding and implementing these concepts, companies can ensure their online presence remains strong and their products and services meet user expectations.
