Facebook downranking system failure

March 2022

Facebook has experienced a 'massive' failure of its content ranking system that exposed users to a surge of disinformation, hate speech and other harmful content, according an internal report obtained by The Verge.

The document attributes the failure to a software bug and says that posts that would usually have been demoted by the company's algorithms were boosted by as much as 30%.

A Facebook spokesman told The Verge the bug 'has not had any meaningful, long-term impact on our metrics.'
