In October 2022, MBI completed development of the first statewide Broadband Serviceable Location (BSL) dataset to support broadband mapping and analysis in Massachusetts. BSLs are locations where wired (e.g., cable or fiber) or fixed wireless broadband service can or has been installed.

The BSL data consists of unique records for each address point and the associated address. Each point is located on the largest, most complex building (identified as the primary building) and the associated address record contains unit counts for locations that have more than one unit.

The BSL data is derived from the state Master Address Database (MAD) maintained by MassGIS and the City of Boston’s Street Address Management (SAM) data and will continue to be updated and improved. The MAD is Next Generation 911 (NG911) street address data maintained by through a joint agreement with State 9-1-1 and partnerships with all MA cities and towns.

Map representing the status of last mile broadband projects.  Towns in the MassBroadband123 service area that were considered "unserved" and "underserved" by broadband qualified for last mile broadband funding support from the Commonwealth. The map differentiates towns according to four categories: (1) towns with fully complete and operational networks, (2) towns with partially operational networks that are still in construction, (3) remaining last mile towns to be completed, and (4) previously served towns not included in the program.

Map of project partners and pathways chosen to construct broadband networks in last mile program towns.  Towns in the MassBroadband123 service area that were considered "unserved" and "underserved" by broadband qualified for last mile broadband funding support from the Commonwealth.

Map of the MassBroadband 123 service area and network, including the location of fiber-optic cables and points of interconnection.  MassBroadband 123 network construction and testing was completed and turned over to the MBI’s network operator in January 2014.

Select a town from the list below to view a map that shows the location of MassBroadband 123 fiber and community anchor institutions (CAI) that were connected in that community as of the completion of the project in January 2014.
