The three applications, all of which are owned by Facebook and run on the same infrastructure, went offline just before 5 p.m. Facebook Messenger and Workplace, among other connected tools, have also ceased operating.

At about 11 p.m., Facebook and Instagram were back up and running for users, but WhatsApp was still down. The social media giant’s services fell down suddenly in June and April this year owing to a “network configuration issue.”

Facebook reveals why the site was down for six hours.

According to an official blog post published Monday evening, the six-hour outage across Facebook’s services, including Instagram, Messenger, Whatsapp, and OculusVR, was caused by configuration changes to the company’s routers, which coordinate network traffic throughout the company’s data centres.

“This network traffic disruption had a cascading effect on how our data centres interacted, halting our services,” the company stated.

There is no evidence that user data was compromised as a result of the outage, according to Facebook.

Facebook apologises for the service interruption.

And that was Netflix’s response to the Facebook outage.

And that’s how users trolled Facebook on outage.

So there are a lot of details in this tale, and I’ll give you a quick rundown of the causes for the outage and let you know the truth.
