Why Was Facebook Down? And How Long Did it Take to Fix?
We’ve all wondered why Facebook was down a few days ago. We’ve been reading articles about unfounded hacker claims, problems with Facebook’s Domain Name System (DNS), and the cost of repairing the outage. But why was Facebook down for so long? And how long did it take to get back online? We’ll answer these questions and more in this article. And we’ll also touch on how long it took to fix the problems.
Problems with Facebook’s Domain Name System
Recent outages of Facebook’s domain name system and related services have been blamed on the company’s Domain Name System (DNS). While Facebook has not released a formal explanation, the outage has left users unsure of the cause of inaccessibility. It was down multiple times and for several hours, and DNS Checker and Down Detector services both reported failures. This may interest you : How to Download Videos From Facebook. The failures were the result of changes to BGP routes, which provide an updated list of possible routes to internet routers. The internet routers use these lists to deliver network packets to their final destinations.
The outage affected many Facebook applications, including Messenger, Instagram, WhatsApp, and Oculus. Employees also had trouble accessing company domain emails. A problem with the DNS is a huge problem for the online website’s MTTR and may be the cause of the Facebook outage. As an Internet infrastructure and security company, Cloudfare explained what caused the problem. The DNS, or domain name system, is the way Internet traffic is routed across the internet. When DNS goes down, packets can end up in black holes.
Unfounded claims of a hacker
A user on a known hacker forum posted a lengthy announcement claiming that a large-scale hack was behind Facebook’s downing. It was a credible claim, as a number of verified Twitter accounts with large followings tweeted about the hack. The article stated that Facebook’s downing could be caused by a single attacker or a group of attackers coordinating the attack. The hack was a result of three software flaws, and the attackers were able to access the accounts of millions of Facebook users.
The AP, BBC, and others have reported on the alleged hacking. They have also said that a hacker group called SEA was responsible for a fake tweet that falsely claimed that Fifa President Sepp Blatter would step down.

These hacks have come from the same hacker group, and the Syrian government denies any involvement.
Cost of fixing outage
The cost of fixing the Facebook outage isn’t an exorbitant one, but it could have been avoided if the company had implemented an automated configuration backup for network devices. A solution such as SolarWinds Kiwi CatTools backs up the configuration of all network devices, allowing you to roll out the last good configuration if something goes wrong.

As of 7pm ET yesterday, the outage was mostly limited to users. It also shut down Facebook staff, locking them out of their offices and internal communication system. Facebook employees were locked out of their offices and unable to determine what was causing the problem, which is an issue for a company that runs everything through its website. Because it’s so difficult to access a server, the company had to send engineers to the main data center in California to fix the problem.
Time it took to get back up and running
On Monday, Facebook’s services were unavailable globally for six hours, but they’ve now been restored. The outage occurred due to changes in Facebook’s backbone routers, which coordinate network traffic between the company’s various data centers. These changes cascaded to all Facebook services and affected users of all countries and time zones. The downtime was felt most by small businesses and creators, who were unable to access the social network.
One of the victims of the outage was Samir Munir, who runs a food delivery business on Facebook and takes orders via WhatsApp. Facebook workers scrambled to fix the problem, which affected its internal systems, including security systems and calendars. Other problems reportedly affected users around the world, including those using the social network’s app Tinder and Spotify. In the aftermath, Facebook announced on Twitter that it was back up and running.
