Duplicate posts introduced for a limited subset of Facebook Pages
This incident has been resolved.
Starting September 2nd, approximately 5,000 Facebook pages began showing duplicate posts. Duplicate posts are visible across all surfaces (Dashboards, Intelligence, Live Displays, Search), could appear anywhere in a Page's timeline history but will be limited to a single extra copy. The most apparent duplicates will be video posts. Duplicates will inflate interactions, video view counts, and post count in Intelligence and Leaderboards. We recognized the issue and have begun a fix, which will be complete by September 14th.
This incident affected: Web Client, Notifications, Search, API, and Chrome Extension.
