Why did Facebook, WhatsApp and Instagram go down

Facebook on Tuesday blamed a “faulty configuration change” for the over 6 hour outage on Monday.

“To all the people and businesses around the world who depend on us, we are sorry for the inconvenience caused by today’s outage across our platforms. We’ve been working as hard as we can to restore access, and our systems are now back up and running,” Facebook’s vice president of infrastructure Santosh Janardhan apologized.

“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 the way our data centers communicate, bringing our services to a halt.”

“Our services are now back online and we’re actively working to fully return them to regular operations. We want to make clear at this time we believe the root cause of this outage was a faulty configuration change.”

Mr Janardhan added that Facebook had no evidence of user data being compromised during the downtime.

The outage comes a day after a whistleblower accused the social media giant of repeatedly prioritizing profit over clamping down on hate speech and misinformation, and said her lawyers have filed at least eight complaints with the US Securities and Exchange Commission.

Frances Haugen, who worked as a product manager on the civic misinformation team at Facebook, appeared on Sunday on the CBS television program “60 Minutes,” revealing her identity as the whistleblower who provided the documents that underpinned a Wall Street Journal investigation and a Senate hearing on Instagram’s harm to teen girls.

Haugen, who previously worked at Google and Pinterest, said Facebook has lied to the public about the progress it made to clamp down on hate speech and misinformation on its platform.

She added that Facebook was used to help organize the U.S Capitol riot on January 6, after the company turned off safety systems following the US presidential elections.

Facebook has been under fire after the Journal published a series of stories based on Facebook internal presentations and emails that showed the social media company contributed to increased polarization online when it made changes to its content algorithm, failed to take steps to reduce vaccine hesitancy and was aware that Instagram harmed the mental health of teenage girls.
