A widespread outage affecting the Facebook (FB) family of apps for more than 14 hours on Wednesday and Thursday remains unexplained.
Worldwide, many users reported issues using Facebook, Instagram, Messenger, Oculus VR and WhatsApp. For some, the websites were down completely, while others struggled with limited functionality. User reports of Facebook being unreachable continued at Down Detector Thursday morning, while Instagram tweeted overnight that service had been restored.
Facebook had to go to Twitter (TWTR) to report that it was investigating the outage, which it said was not the result of a distributed denial of service, or DDoS, attack.
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.
