Chile’s Lotería de Concepción filed a lawsuit in 2024 demanding telecom operators block overseas illegal‑gambling websites. In September 2025, the Supreme Court of Chile ordered ISPs to carry out website blocking. Yet illegal platforms kept creating mirror sites and hampered enforcement. In March 2026, the Santiago Court of Appeals ruled that existing laws do not oblige telecom companies to deploy intrusive active inspection technologies such as Deep Packet Inspection (DPI). The judicial case was closed, and regulatory disputes shifted toward legislative reforms governing online gambling.
On 11 June 2026, SUBTEL timely submitted its technical‑assessment proposal to the court. It openly acknowledged no technology can permanently block gambling mirror‑sites with a 100 % success rate. The document compares three mainstream technologies: DPI is highly intrusive and endangers privacy and network neutrality; SNI filtering can be easily bypassed by encryption; DNS domain blocking brings minimal interference and is currently the option best aligned with regulatory requirements.
SUBTEL has designed an inter‑agency collaborative workflow: aggrieved parties identify domain names, the gambling‑regulatory authority verifies their illegal status, SUBTEL distributes block‑lists to operators including Claro, Entel, WOM and Movistar. Operators implement DNS blocking within deadlines and continuously track newly‑emerged mirror domains. The whole solution adheres to the principles of moderation and proportionality, avoids mass‑traffic inspection and prevents wrongful blocking of legitimate services.
