The US Senate is voting Wednesday on whether to put the FCC's net neutrality rules back in place. The Senate resolution would overturn a vote by the FCC in December to abandon its open-internet regulations. The resolution has drawn the support of half of all senators, but will need a majority to pass. Even if it passes, the resolution faces a dubious future, because it needs to be passed by the House of Representatives and signed by President Trump. Without net neutrality internet service providers can block, slow, or give preferential treatment to particular online sites or services.
