Facebook, WhatsApp, Instagram Suffer Worldwide Outage

Facebook said late Monday that “the root cause of this outage was a faulty configuration change” and that there is “no evidence that user data was compromised as a result” of the outage. The company apologized and said it is working to understand more about the cause, which began around 11:40 a.m. ET Monday.
