The Mistake that Caused 1.1.1.3 to Block LGBTQIA+ Sites Today

On April 1st, Cloudflare launched a filtered DNS service called "1.1.1.1 for Families" that allows users to restrict certain categories of websites. However, an error occurred whereby some sites related to the LBGTQIA+ community were inadvertently blocked due to incorrect categorization data from one of their licensed providers. The company immediately rectified the issue by removing the wrong "Adult Content" category and creating a new data structure with the correct definition. They also set up checks for known sites that should not be blocked in future updates.
