The map shows where Northern Telephone offers fiber internet service. When different max speeds are available at different addresses within a hex, color is determined by the fastest speed.
Colored hexagons indicate where Northern Telephone services at least one address. Internet service is not necessarily available at every location within a colored hex.
Along with fiber, Northern Telephone also offers DSL. See Northern Telephone DSL Availability.
Broadband Map's information on Northern Telephone fiber availability relies heavily on the May 2026 release from the FCC's Broadband Data Collection program (representing ISPs' availability as of December 2025).
