Facebook’s 6-Hour Outage and the Social Response

The interconnectivity of communities and dependence on social media became glaringly apparent on October 4, 2021, when the Facebook Family of Apps abruptly went offline around the globe. Within minutes, users turned to Google, Twitter, and other online resources to determine if it was just their channels or more widespread.


While users felt the burn of not being able to engage with the family, friends, brands, and influencers – advertisers and small businesses were deeply impacted. To make matters worse, the blackout occurred the day after a blistering 60 Minutes Report by a former employee whistleblower and just hours after they opened over 4% down on the Stock Market. By the end of the 6 hours, some experts estimated the platform affected 35 million users globally, and the tech giant lost approximately $6 billion in revenue between stock and ad placements.

Just How Widespread Was the Facebook Outage Issue?

Real-time monitoring website Downdetector, says the Facebook outage was the largest ever tracked with over 14 million reports globally. The volume of reports for Facebook and Instagram charted below demonstrates the initial response, followed by the lull as users understood this was not an immediate fix.

Additionally, the Facebook outage generated a similar response on Google, with a considerable spike in search volume reported by Google Trends. All of the top five related terms and queries reached “breakout” status – meaning the interest grew by more than 5,000% during the measured timeframe.

What Exactly Happened to Cause the Facebook Outage?

When attempting to access Facebook and Instagram, users we met with either a Domain Name System (DNS) error or a 5xx server error. In a release shared on Facebook Engineer’s website, the platform shared:

Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on how our data centers communicate, bringing our services to a halt.

With such a brief explanation, web experts provided further insight into the logistical nightmare.

Think of the DNS as sort of the telephone book of the internet. When you enter a domain name into a web browser, the DNS translates that into an IP address (so you don’t have to memorize it) to access the website information. But – this was just part of the issue. It appears that Facebook also somehow removed the Border Gateway Protocol (BGP) route, which is houses the IP addresses and DNS server names and acts as the GPS system.  Without the BGP route, the scheduled routine maintenance led to Facebook’s domain falling off the internet’s “map.”

Social Media’s Response

As the social media community came to odds with the Facebook channels being down, users turned to Twitter for both news and comedic relief. A commonplace for people to find answers, Twitter saw sizeable hashtag usage of #InternetShutDown, #Facebook, and #FacebookDown, which saw more than 1.5 million posts alone. The below map generated by One Million Tweet Map illustrates where the conversations were generated. Not surprisingly, these are a close correlation to the reporting map.

One of the more entertaining outcomes of the outage was the commentary from brands and user-generated memes.  Surprisingly, Twitter itself had one of the most highly engaged tweets during this time as they made light of the increased traffic. Brands were quick to trend jack to increase awareness and engagement – for many, it worked.

Memes and Gifs Galore

These days memes and gifs are commonly used online pop culture language that conveys users’ sentiment. As millions waited for the Facebook Family of Apps to come back online during the outage, creative content was flowing on alternate websites such as Twitter and TikTok. Below is a sampling of memes shared.


While the Facebook outage created a stressful day for many, one lesson to be learned is that brands must be nimble in the event a social channel goes down. Additionally, joining in on globally relevant conversations can increase social media engagement and impressions when the opportunity presents itself.
