How to Format a Bulk Fabric Challenge

As part of the Broadband Data Collection (BDC), the public will have the opportunity to submit challenges, or proposed corrections, to the information in the FCC’s Broadband Serviceable Location Fabric (Fabric). 

  • Service providers, governments, and other entities and organizations will be able to submit bulk challenges to the Fabric in the BDC system once the window for submission of bulk Fabric challenges opens.  This window opened on September 12, 2022 BDC filing deadline. 
  • Individuals will have the opportunity to submit single-location challenges to the Fabric from the FCC’s Broadband Map once the Map is published. 

Bulk Fabric Challenge Data includes information about a dispute with, or proposed correction to, the Fabric.   

  • Each bulk Fabric challenge data file must contain records of each location being challenged in a Comma Separated Value (CSV) format and match the specification provided in the table below. 
  • All fields must be included in the file upload, and all values must conform to the descriptions, codes, or formats identified for each field.  The file must include a header row where the field names match those listed below. 
  • The FCC and its Fabric contractor, CostQuest, will receive and review the bulk Fabric challenge data.
