Why was Facebook Down?
You may have noticed that Facebook, along with its associated platforms, Instagram and WhatsApp, experienced a significant outage on Monday, October 4th, 2021.
The outage lasted for approximately six hours, causing frustration and confusion for users worldwide.
So, what caused the outage? According to Facebook, the root cause of the downtime was a faulty configuration change made by an engineer during routine maintenance work.
This unintentional command took down the entire platform, along with its associated services.
The outage was one of Facebook’s worst setbacks since a 2019 incident that took the platform offline for almost 24 hours.
The downtime affected not only individual users but also businesses and organizations that rely on Facebook’s advertising and communication services.
The outage also highlighted the fragility of centralized platforms like Facebook, which have become integral parts of our daily lives.
While Facebook was quick to restore its services, the incident raises questions about the platform’s reliability and the potential impact of future outages.
Role of Internal Systems
When Facebook went down for several hours, it wasn’t just the public-facing services that were affected.
The outage also broke nearly all of the internal systems that Facebook employees use to communicate and work.
In this section, we’ll look at the role that internal systems played in the outage and how they were impacted.
Role of Configuration Changes
One of the key factors that led to the outage was a configuration change that was made to Facebook’s routers.
This change was intended to optimize network traffic, but it ended up causing a wave of disruptions that took down Facebook, Instagram, and WhatsApp.
The exact details of the configuration change are not known, but it’s clear that it had a significant impact on the company’s internal systems.
In particular, it appears that the change caused problems with Facebook’s backbone routers, which are responsible for routing traffic between data centers.
Impact of Backbone Routers
The backbone routers are a critical component of Facebook’s infrastructure, and any issues with them can have a major impact on the company’s services.
In this case, the configuration change caused the routers to become overloaded, which led to a cascading series of failures that took down the entire network.
As a result of the outage, Facebook has been scrambling to fix its internal systems and prevent similar incidents from happening in the future.
The company has acknowledged that it needs to do more to ensure the reliability of its network, and it has promised to take steps to improve its infrastructure and processes.
The DNS Factor
If you were trying to access Facebook on the day it went down, you might have received an error message that said, “Sorry, something went wrong.
We’re working on getting this fixed as soon as we can.”
This error message was a result of a Domain Name System (DNS) failure that caused Facebook to become unavailable.
Domain Name System Explained
The DNS is like a phone book for the internet.
It is responsible for translating human-readable domain names, such as www.facebook.com, into IP addresses that computers can understand.
When you type a URL into your web browser, your computer sends a request to a DNS server to look up the IP address associated with that domain name.
Once the IP address is found, your computer can connect to the website’s server and load the webpage.
Influence of DNS on Outage
During the Facebook outage, the DNS played a critical role in the failure.
The root cause of the outage was not the DNS itself, but rather the Border Gateway Protocol (BGP) routes that Facebook uses to advertise its DNS nameservers to the internet.
When these BGP routes were withdrawn, the IP addresses of Facebook’s DNS nameservers became unreachable, and users were unable to access Facebook.
The DNS outage also affected other services that rely on Facebook’s infrastructure, such as Instagram and WhatsApp.
This is because these services use the same DNS infrastructure as Facebook.
When the DNS failed, these services were also unable to function properly.
Impact on Facebook Owned Platforms
The Facebook outage on July 28, 2023, affected not only the social network but also its family of apps, including Instagram, WhatsApp, and Messenger.
Here’s how the outage impacted each platform:
Instagram, the photo-sharing app owned by Facebook, was also down for several hours, leaving its users unable to upload photos, videos, or stories.
The outage impacted millions of users who rely on the platform for socializing, entertainment, and business purposes.
The Instagram outage also affected businesses and influencers who use the platform to promote their products and services.
According to a report, the outage caused a loss of revenue for many businesses that rely on Instagram for marketing.
WhatsApp, the instant messaging app owned by Facebook, was also impacted by the outage.
The app was not functioning properly, and users were unable to send or receive messages, make calls, or access their chats.
The WhatsApp outage caused inconvenience to millions of users who rely on the app for communication with friends, family, and colleagues.
The outage also impacted businesses that use WhatsApp for customer support and sales.
Messenger, the messaging app owned by Facebook, was also down for several hours, leaving its users unable to send or receive messages, make calls, or access their chats.
The Messenger outage impacted millions of users who rely on the app for communication with friends, family, and colleagues.
The outage also impacted businesses that use Messenger for customer support and sales.
User Experience During the Outage
During the six-hour outage of Facebook, Messenger, Instagram, and WhatsApp, users all around the world were left in a state of confusion and inconvenience.
Here’s what you experienced during the outage:
Inconvenience Faced by Users
As a user, you may have experienced inconvenience in accessing your social media accounts.
You may have tried refreshing your feeds, but to no avail.
You may have also tried logging in and out of your accounts, but the issue persisted.
The outage may have disrupted your daily routine, especially if you rely on social media for work or communication.
Status Updates and Messages
If you were in the middle of posting a status update or sending a message, you may have encountered an error message or a blank screen.
Your posts and messages may have failed to upload or send, leaving you unsure if your friends and followers received them.
You may have also missed important updates and messages from your online friends.
To make matters worse, Facebook’s outage occurred during a time when people are heavily reliant on social media for communication and information due to the ongoing pandemic and remote work.
Third Party Influence on the Outage
Role of Cloudflare and Fastly
During the Facebook outage, many users noticed that other websites and services were also affected.
This is because Facebook relies on several third-party services to ensure that its platform runs smoothly.
Two of these services are Cloudflare and Fastly.
Cloudflare is a content delivery network that helps websites load faster by caching content and distributing it across multiple servers.
Fastly, on the other hand, is a content delivery network that specializes in video and image delivery.
Both companies provide critical services that help Facebook deliver content to its users quickly and efficiently.
However, during the outage, both Cloudflare and Fastly experienced issues that affected their ability to deliver content.
This, in turn, caused problems for Facebook and its users. While the exact cause of the issues is still unknown, it is clear that the outage was not entirely Facebook’s fault.
Impact on Third Party Developers
The Facebook outage also had a significant impact on third-party developers who rely on the platform’s APIs to build their own apps and services.
Many of these developers were unable to access Facebook’s APIs during the outage, which meant that their apps and services were also affected.
This highlights the risks of relying on a single platform for your business or service.
While Facebook provides a valuable service to developers, it is essential to have backup plans in place in case of outages or other issues.
Detection and Reporting of the Outage
