Facebook bug marks private posts public
Between May 18 and May 22, a bug in Facebook's system changed the settings on 14 million users' accounts so that newly posted updates they thought were private might have been made public instead. The company attributed the error to a mistake made in redesigning how the public parts of user profiles are displayed. After Facebook found the bug, it was another five days before all privacy settings were correctly restored.
