What Is s.cdn.turner.com?

This domain supports Turner’s media properties by delivering content while simultaneously tracking your behavior. It logs what you watch and how you interact, feeding this data into advertising systems. As Privacy Auditors, we’re alarmed by how such tracking erodes your personal privacy under the guise of content delivery.
