Understanding How Facebook Disappeared from the Internet: The Surprising Benefits of Forgetting

In the vast landscape of the internet, there are mechanisms at play that keep everything connected and functioning seamlessly. One such mechanism is BGP, or Border Gateway Protocol. BGP acts as a means to exchange routing information between autonomous systems (AS) on the internet. Without BGP, the internet routers would be clueless, unable to navigate the vast network. It's like someone suddenly pulling out all the cables from the data centers, leaving them disconnected from the internet. Facebook, being a part of this intricate web, relies on BGP to advertise its presence to other networks. Every Autonomous System (AS) needs to announce its prefix routes using BGP, otherwise, it becomes invisible and disconnected from the internet.

On a particular day, at 1658 UTC, something unusual happened. Facebook stopped announcing the routes to their DNS prefixes. This meant that Facebook's DNS servers were no longer accessible. It was as if they had disappeared from the internet. Without the route announcements, Facebook and its sites effectively disconnected themselves from the rest of the internet. DNS resolvers, including ours and everyone else's, had no way to connect to their nameservers. The impact was massive, leaving millions of users unable to access Facebook's services.

Interestingly, the concept of forgetting plays a significant role in the functioning of our brains as well. Memories are distributed across our cortex, but there are specific regions that can be considered hubs, where the mechanics of memory take place. The hippocampus, nestled deep in our brains, is responsible for the save function. It allows us to store information into a sort of hard drive. On the other hand, the prefrontal cortex, located right behind our foreheads, is involved in the retrieval of memories. And towards the back of the brain, there are regions that store the memories we typically think of.

When we remember something, the tips of our neurons in the posterior area grow, strengthening the connections associated with that memory. Forgetfulness, on the other hand, causes the tips to wilt back down, resulting in the weakening or forgetting of that memory. The ability to forget is crucial for our cognitive abilities, particularly in generalizing and sorting information. If we were to remember everything, it would make it harder to abstract, filter, and make sense of the vast amount of information we encounter.

Imagine a life where everything was novel, where even the most familiar things provoke a sense of novelty and anxiety. This is why forgetting is essential for our well-being. It allows us to let go of emotional memories and avoid perseverating over them. Forgetting helps us move on and not be weighed down by the emotional component of past experiences. Forgetting also plays a role in exposure therapy, where traumatic memories can be re-balanced by associating them with more benign experiences.

Sleep, too, is a crucial aspect of forgetting. During sleep, the mechanisms that result in memories wilting back down, allowing us to let go of the accumulation of memories in our posterior cortex. This is why most creative individuals seem to function best in the morning. The ability to create unexpected associations requires a certain level of forgetting. If our memories were solid, like steel, without any room for looseness or play, we would never experience those eureka moments that define creativity.

Memory, while a valuable asset, can sometimes hinder decision-making. People who heavily rely on their memories are more prone to making errors in judgment. This is because they tend to over-index their memories, thinking they already know everything there is to know. On the other hand, individuals with what we may consider a "bad memory" often make better decisions. They are more likely to double-check information, ensuring they have a complete and accurate understanding of the situation before making a decision.

In conclusion, the disappearance of Facebook from the internet highlights the importance of BGP in keeping networks connected. Similarly, the concept of forgetting plays a vital role in our cognitive abilities and overall well-being. Forgetting allows us to let go of emotional memories, be more creative, and make better decisions. Here are three actionable pieces of advice based on these insights:

1. Embrace forgetting: Recognize that forgetting is a natural and necessary process for our brains to function optimally. Don't be afraid to let go of emotional memories and focus on moving forward.

2. Double-check information: Instead of relying solely on your memory, take the time to double-check information before making important decisions. This ensures that you have accurate and up-to-date information to base your choices on.

3. Foster creativity through unexpected associations: Encourage creativity by allowing room for unexpected connections and associations to form. Don't be afraid to forget certain details and embrace the possibilities that come with new perspectives.

In the end, understanding the intricacies of BGP and the benefits of forgetting can help us navigate the digital landscape and our own minds more effectively.
