Research

CheckInternetAvailability.com is built on the FCC's Broadband Data Collection — the same provider filings that power the National Broadband Map. Because we process those filings at the census-block level for every state we cover, we end up with a detailed picture of what the map does and does not say about rural connectivity. This section is where we publish that work.

Each brief states its data sources, vintages, definitions, and limitations in full, and ships with a downloadable dataset so that journalists, state broadband offices, and researchers can check our numbers rather than take our word for them. We do not name or rank individual providers in research pieces; the subject is the map and the filing rules, not any operator's service. If you use this work, please cite it and link back, and tell us what you found — corrections and questions go to jho@ispadvisor.com.
