Atherton Fiber state-reach reading
Atherton Fiber sits in the lower third of Form 477 providers by record volume (< 329). Thin filing books still matter when they dominate one state or a niche technology pocket rather than a national residential footprint.
California alone accounts for 100.0% of Atherton Fiber's filings (297 of 297), a concentrated book where one state can swing the national picture. Form 477 historically let providers mark a whole census block from a single reachable address; treat these counts as declared capability, not address-level availability, speed, or price.
