About this data

This service mirrors the FCC Broadband Data Collection and serves it with explicit provenance, vintage, and comparability rules.

What the figures mean

• Availability, not adoption. Providers report where service is or could be offered within ten business days of a request. These figures do not say how many people subscribe.
• Advertised, not measured. Speeds are maximum advertised speeds, not speeds observed at a customer premises.
• Cumulative tiers. A unit counted at 100/20 Mbps is also counted at 25/3. Tier shares must never be summed.
• Overlapping partitions. Total already contains urban plus rural, and tribal plus nontribal. Exactly one partition is reported at a time.
• Mobile is area-based. Mobile coverage is a share of land area, not of units, so it cannot be compared with fixed shares.

What this service cannot tell you

The FCC Broadband Serviceable Location Fabric maps an address to a specific serviceable location. It is licensed separately by CostQuest and is not redistributed here. A coordinate lookup therefore resolves to the census geography containing the point and reports that area; there is no address-level answer.

How often it updates

Providers file availability as of 30 June and 31 December each year, due the following 1 September and 1 March. The published map typically follows several months later, and a vintage can be revised after publication. This service polls daily and ingests only when a new vintage or a changed artifact inventory appears, so the update cadence of the data is twice yearly even though the check is daily.

Adding another source

FCC BDC is one registered source adapter, not a hardcoded assumption. Other publishers are added behind the same normalized model, so every area and comparison response keeps the same shape. See the registered sources.
