Content delivery network provider Netskrt's "State of the ISP Survey" found that live sporting events are the global infrastructure's most daunting streaming challenge and that the biggest worry is traffic generated by American football. The long-term study - conducted between May and August 2025 - includes input from 55 global internet service providers (ISPs). Almost eight in ten survey respondents (78%) said sports cause them the most concern related to streaming reliability. Of these, 70% pointed to American football as the most challenging sport to deliver. International football (soccer) is quickly approaching similar levels.
