    NH tech firm taps new chief executive

    Dyn Inc., a New Hampshire company that helps businesses monitor and route Internet traffic through complex networks of data centers, has hired longtime tech-industry executive Colin Doherty as its new chief executive.

    Doherty replaces Dyn founder Jeremy Hitchcock, who resigned abruptly in May after the company announced a $50 million private investment round. At the time, Hitchcock said Dyn needed a leader better suited to running a large company seeking to expand its sales.

    Dyn’s software connects easy-to-remember website names to the series of digits that make up a site’s actual Internet address. It also sells software that can monitor Internet traffic problems and route users to the most efficient data center in a network.


    In an interview, Doherty said he was comfortable piloting the company toward a larger customers in the global IT market, which he said is dealing with a “massive disruption” as companies shift more resources to remotely operated or rented “cloud” computing.

    “If you’re on a website and the page doesn’t load, or it goes black, as a consumer you’re incredibly irritated. As a business, you’re losing tens or hundreds of thousands of dollars an hour,” Doherty said.

    Doherty most recently worked as a sales vice president and CEO of Arbor Networks, a cybersecurity software seller. Dyn downplayed any difficulty in replacing a founding CEO, noting in part that Hitchcock is still involved as a board member.

    Privately held Dyn has about 430 employees worldwide, with about 350 at its headquarters in Manchester, NH. The company said its annual sales are close to $100 million, with customers including Twitter, Zillow, Hershey’s, and British Telecom.
