How to interpret this data

Coverage percentages describe imported provider filings, not measured network performance. Advertised maximum speeds are the highest reported tier and may not be available at every location. Residential and business availability are shown separately where the public dataset supports that distinction.

For observed performance, use the Internet Analysis speed test and compare it with the relevant United States internet speed report.
