Last Friday was a major milestone in the process of moving $42.5 billion from the federal government to states to distribute mostly to rural areas to build new, modern Internet access networks. January 13th marked the deadline for error corrections (called challenges) to the official national map that will be used to determine how much each state will get. As an organization that has worked in nearly all 50 states over the past 20 years on policies to improve Internet access, we spent the last few weeks struggling to understand what was actually at stake and wondering if we were alone in being confused about the process. Despite the stakes, almost no expert we talked to actually understood which challenges – if any – would fix errors in the map data before it was used to allocate the largest single federal broadband investment in history.
