Facebook users around the world reported that they had problems logging into Facebook, Instagram and WhatsApp, and they could not post. Facebook posted a message acknowledging the disruption of the service, although the incident was not related to DDoS, the specific reasons are not confessed.
We're focused on working to resolve the issue as soon as possible, but can confirm that the issue is not related to a DDoS attack.

Roland Dobbins, a chief engineer of network security management company Netscout, believes that the downtime may be caused by a BGP routing error. He said,
Roland Dobbins, principal engineer at Netscout's Assert team, says he has no data whatsoever to support that claim that a BGP leak is the cause of today's Facebook or Instagram outages. "There was an internal miscomm here," he says of the email PR people sent to reporters.

However, cloud monitoring company ThousandEyes believes that “the cause would appear to be internal rather than a network or Internet delivery issue–for example, we saw ‘500 internal server errors’ from Facebook. Given the sheer scale and continuous changes that these web-scale providers are constantly making to their applications and infrastructure, sometimes things break as a result of these changes, even in the most capable hands.”
Today, Facebook sent a tweet to respond positively to the cause of the accident. It said that it was due to changes in server configuration that caused the downtime, and said that the problem has been solved and the system is recovering.
Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We've now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience.
