Across the 115.3M Broadband Serviceable Locations (BSLs) in the US, there have been fluctuations in their broadband service availability status as multiple versions of the Fabric and Broadband Data Collection (BDC) data are published. For Version 3 of the Fabric locations and BDC data, some BSLs moved to unserved, underserved, served, and some BSLs were added and dropped due to self and public challenges made to the data.
Below is an analysis of how and why the data changed from October 17, 2023, to 11/17, 2023, along with a high-level look at the most unserved areas across the US as of 11/17/2023.
When we compare 10/17/2023 BDC service availability data to the BDC data as of 11/17/2023, we see the following:
- An increase in the number of “served” BSLs
- From 102M to over 105M BSLs
- A decrease in “unserved” locations
- From 8.5M to 7.2M
- A slight decrease in “underserved” locations
- From 3.6M to 3.0M
What is causing the decrease in “unserved“ Broadband Serviceable Locations?
Four primary reasons the BDC data fluctuated in the 11/17/23 BDC data:
- New BSLs were added to the Fabric
- BSLs were dropped
- Unserved BSLs moved to served or underserved
- Underserved BSLs moved to served
From the previous 8.5M unserved locations in the 10/17/2023 BDC data to the 7.2M in the 11/17/23 data, there was a total decrease of 1.3M unserved locations.
- 0.5M were new BSLs
- 2.6M that were unserved moved to either served, underserved, or dropped from the Fabric
- 0.4M that were previously served moved to unserved
- 0.41M that were previously underserved moved to unserved
8.5M + 0.5M – 2.6M + 0.4 + 0.41 = 7.2M unserved locations

Closing thoughts
As new network buildouts, housing structures, and technology updates occur, combined with updated service availability data and data challenges from the FCC’s Broadband Data Collection and CostQuest’s Fabric locations, we will continue to see more fluctuations in the BDC service availability data over time. The future iterations of the data continue to give us a granular look at the Broadband Serviceable Locations that are served, underserved, and unserved and track the progress of expanding broadband coverage across the U.S.

Coverage definitions used in analysis
Served – access to a low-latency Fiber, Cable, Copper, or Licensed Terrestrial Fixed Wireless offering of speeds greater than or equal to 100 Megabits per second (Mbps) download and 20 Mbps upload, or 100/20 Mbps (download/upload).
Underserved – access to a low-latency Fiber, Cable, Copper, or Licensed Terrestrial Fixed Wireless offering of speeds less than 100 Megabits per second (Mbps) download and 20 Mbps upload, or 100/20 Mbps (download/upload) but greater than or equal to 25 Megabits per second (Mbps) download and 3 Mbps upload.
Unserved – without any Terrestrial Broadband Service or with internet service offering speeds below 25/3 Mbps (download/upload) or latency greater than 100 milliseconds.
*For this analysis and data dashboard we don’t include unlicensed fixed wireless or satellite technologies when determining coverage status – following NTIA BEAD requirements.
