The FCC released a public notice with its initial list of census blocks and a map of areas that are potentially eligible for bidding upon in the upcoming RDOF Phase I auction.  The release of this list commences the RDOF’s limited challenge process, in which parties have until April 10, 2020 to inform the FCC of census blocks that should not be deemed eligible for support through the auction.  It will be important for ACA Connects members to participate in the challenge process if census blocks in which you serve any location with voice and at least 25/3 Mbps broadband service are included on the preliminary list.
