Sullivan County High-Speed Internet Expansion: Track Progress Online

As fiber-optic conduit is installed across Sullivan County, officials have launched a new website designed to help residents and businesses track progress on a major high-speed internet expansion project and check future service availability.

The site, connectsullivan.com, went live this month as construction continues on a roughly $29.9 million broadband infrastructure initiative funded through New York’s Empire State Development ConnectALL Program and administered through federal capital project funding.

County officials say the project, in partnership with private provider Archtop Fiber, will extend broadband service to more than 22,000 homes and businesses across Sullivan County, New York, using a mix of underground fiber lines and wireless service for more remote areas.

“The County, NYS’ ConnectALL team, consultant ECC Technologies and our private partner Archtop Fiber have been working hard this past year to advance the dream of a Sullivan County with high-speed Internet access wherever you live, work or play,” said Sullivan County Manager Joshua Potosek. “You can see the results of this work by visiting connectsullivan.com, offering general information, an interactive map of availability and a signup form for updates.”

Empire State Development President, CEO and Commissioner Hope Knight said the project is part of a broader statewide effort to expand digital access.

“Through ConnectALL, New York State is making strategic investments to ensure every community – regardless of geography – has access to reliable, high-speed Internet,” Knight said. “The launch of connectsullivan.com is an important step in that effort, giving residents and businesses a way to track progress, check availability, and stay informed as this transformative project moves forward.”

Officials say Archtop Fiber is currently deploying more than 220 miles of fiber-optic cable, most of it buried underground. The county will own the infrastructure, while Archtop Fiber and Hudson Valley Wireless will serve as internet providers.

“This initiative reverses that trend for many of the unserved homes in the county and creates new opportunities in health, education and economic well-being,” said Lorne Green, commissioner of Information Technology Services for Sullivan County, New York.

Green said the county’s rural terrain and low population density have historically limited broadband investment.

Archtop Fiber Chairman and CEO Jeff DeMond said the project represents a long-term investment in the region.

“It’s partnerships like this that truly move the needle for underserved communities,” DeMond said. “We are dedicated to connecting homes, empowering businesses, and ensuring that every resident has access to the fastest fiber Internet that makes modern life possible.”

Service is expected to begin in early May in the Liberty area, with expansion continuing through 2026.

The website allows users to check current and planned service availability by address, view fiber construction progress, estimate potential wireless coverage areas, sign up for updates, and review project timelines and frequently asked questions.

Officials said the project is supported by a grant awarded to Sullivan County through the ConnectALL Municipal Infrastructure Program, funded by the U.S. Department of the Treasury’s Capital Project Fund.
