The growing number of orders to block websites and applications is creating new challenges for Internet stability in Latin America. When such measures are implemented directly at the IP address level, they may unintentionally affect numerous legitimate services that share the same infrastructure. This research seeks to measure and understand this collateral impact through observations carried out across different Internet service providers, identifying how blocking measures are implemented, where they occur, and what effects they have on other content and services. Based on this evidence, the project aims to improve visibility into these interventions and provide technical information that can contribute to dialogue between operators and authorities, supporting more precise measures with less impact on Internet stability and resilience across the region.
