Yesterday’s global outage that affected access to Facebook service was the biggest since the company came into existence. The outage affected millions of users across several regions, continents and countries—and according to Facebook, this was caused by a “server configuration change.”
In a post on its Twitter page, Facebook blamed the outage on a server configuration change, but fell short of giving further details as to what that was all about. The company said the issue has now been resolved, and all systems are recovering from the outage.
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.

While the outage lasted, millions of people across the globe were anxious to know what exactly was the cause as they could not access their accounts. The outage, which also affected Instagram, was not the first of its kind, but could as well be regarded as the biggest in the history of Facebook.
Things are since back to “normal” as millions of users now have access to their accounts both on Facebook and Instagram.
Last December, Facebook said its team internal team discovered a photo API bug that “may have affected people who used Facebook Login and granted permission to third-party apps to access their photos.” While Facebook said the issue had been fixed at the time, it however, went on to add that some third-party apps may have had access to “a broader set of photos than usual for 12 days between September 13 to September 25, 2018.”
Last June, the company said a software bug led some users to inadvertently post publicly by default regardless of their earlier settings. The social media giant said as many as 14 million accounts were affected by the bug that occurred sometimes in May.
Users may have unknowingly made their private post public because the bug rendered previous settings ineffective or void. The implication of this is that some of your private posts may have been unintentionally shared publicly.
Facebook notified those affected by the bug by asking them to review any posts they made during the period in question. A notification appears on the Facebook page of affected users when they log in; this takes them to a page with more info where they are able to review all posts made within the period in question.
“We recently found a bug that automatically suggested posting publicly when some people were creating their Facebook posts. Today we started letting the 14 million people affected know – and asking them to review any posts they made during that time. To be clear, this bug did not impact anything people had posted before, and they could still choose their audience just as they always have,” Facebook said at the time.
