Some of Facebook, Instagram and WhatsApp’s more than 2 billion users were unable to access the online services from Wednesday until Thursday afternoon as the social network and its sister apps suffered a prolonged outage.
Facebook confirmed on Twitter that its suite of apps were offline for some users, stemming from server issues. But the company said Thursday that it has fixed the problem and that its systems are “recovering.”
“We’re very sorry for the inconvenience and appreciate everyone’s patience,” Facebook said.
On Wednesday, Facebook dispelled speculation that the outage was caused by a denial-of-service attack (DDoS), a type of cyberattack that disrupts an online service by flooding it with requests. Facebook said it was working to resolve the issue but didn’t announce the fix until Thursday.
Before Facebook’s latest update, Instagram came back online. On Twitter, the company posted a GIF of a jubilant Oprah Winfrey, exclaiming, “Anddddd . . . we’re back”
According to the website Downdetector, Facebook’s outage spanned the globe, with reports of disruptions concentrated on the U.S. East Coast and in the U.K.
Facebook estimates that 2.7 billion people use its apps, with more than 2 billion users posting and messaging on its services every day. The outage prompted exasperation from business owners and individuals who rely on Facebook’s platforms to communicate, and inspired a flood of derision on Twitter, where some users migrated to stay connected.
The prolonged disruption could have financial consequences for the company. Facebook product director Rob Leathern said on Twitter that people were also unable to access the social network’s ad interfaces, which may exacerbate any lost revenue from the outage.
Shares of Facebook were down more than 1.5 percent Thursday afternoon.
