EST A Facebook spokeswoman told Mashable that the outage was due to a change to the site’s configuration systems, and not a hacker attack. This was not the result of a third party attack but instead occurred after we introduced a change that affected our configuration systems. We moved quickly to fix the problem, and both services are back to 100% for everyone., she said.
UPDATED: Tuesday, Jan. 27 / 2:14 a.m. EST — Facebook, Tinder and Twitter appear to be back to normal after a 40 minute outage and mass freak out.
Mobile apps and website versions of the sites have gone down for some users, while others have been experiencing intermittent issues since 12:10 a.m. EST, according to downdetector.com, which monitors disruptions to Facebook’s services.
It is unclear at this time the reason for the issue. Facebook, which also owns Instagram, said in a statement emailed to Mashable: “We’re aware that many people are currently having trouble accessing Facebook and Instagram. We’re working to get things back to normal as quickly as possible.”
