Los Alamos County Announces Four ISPs for Retail Atomic Fiber Service

The Incorporated County of Los Alamos announced Feb. 24 that four internet service providers have contracted to offer retail service on Atomic Fiber, the county-owned open-access broadband network. The county press notice named XMission and Anthem Broadband among the four signatories and identified the agreements as retail-service contracts tied to Atomic Fiber infrastructure.

Atomic Fiber is established as a county-owned open-access network, and the Feb. 24 notice framed these contracts as retail arrangements operating on that municipal fiber system. Because the infrastructure remains county-owned, the contracts place private providers in the retail role while the county retains ownership of the physical fiber plant, according to the language used in the announcement.

The press notice listed XMission and Anthem Broadband by name but did not disclose the identities of the two additional contracted providers. The county release likewise did not include service start dates, neighborhood rollout maps, pricing tiers, or specific subscriber sign-up instructions in the text made public Feb. 24.

For Los Alamos County residents, the distinction between retail providers and county ownership matters for consumer choice and accountability. An open-access model where multiple ISPs sell over a single public fiber network can create competing retail offers and varied pricing, but that outcome depends on the launch timetables, service footprints, and subscription terms that the county has not yet published.

Institutionally, the Feb. 24 contracts represent a concrete step in operationalizing Atomic Fiber after the county built the network. The Incorporated County of Los Alamos now faces implementation choices that will determine how quickly households and businesses in neighborhoods across the county can move from the county announcement to active service with one of the four providers. County officials will need to release rollout schedules and technical details so residents and local institutions can plan for installations, billing, and any required equipment.

The announcement also creates immediate policy questions for county decision-makers. With four retail contracts now in place on Atomic Fiber, Los Alamos County will have to oversee service-level agreements, enforcement mechanisms, and a transparent process for future provider onboarding to preserve competitive access on the publicly owned network.

The Feb. 24 release is the first public verification that Atomic Fiber will carry multiple commercial retail brands; the next essential items for residents are the missing operational details. County officials will determine the speed and scope of service availability by publishing provider start dates, neighborhood coverage maps, and consumer enrollment information.
