Save the Internet Act of 2019 This bill updates the regulatory framework for broadband access. Specifically, the bill repeals a 2017 order adopted by the Federal Communications Commission (FCC) that classifies broadband internet access service as an information service, therefore placing it under Federal Trade Commission authority. The order also expands the public transparency rules and preempts local and state laws that conflict with the regulatory framework. The bill restores a 2015 FCC order, which classifies both mobile and fixed broadband internet access services as telecommunications services, therefore placing the services under FCC authority. Additionally, the bill would create a general conduct standard and restore regulations, including those that prohibit blocking, throttling, and paid prioritization. The bill establishes an exception for small businesses to certain transparency requirements relating to performance characteristics and network practices, and it directs the FCC to engage with tribal stakeholders regarding broadband access service challenges on tribal lands. Among other reports, the bill requires the Government Accountability Office to report on the internet ecosystem, the importance of open internet rules to vulnerable communities, broadband internet access service competition, high-speed infrastructure, challenges to accurate broadband mapping, and the benefits of stand-alone broadband.
