Internet performance and management company Dyn acquires Renesys

Dyn, the internet performance and management company Wednesday said it has bought Renesys, which provides networking information to internet service providers (ISPs). With the acquisition, Dyn plans to launch its new Performance Assurance product line geared to help its enterprise-level clients get a better picture of networking activity throughout the globe.

In an interview Dyn CEO and chairman Jeremy Hitchcock said the two companies complement one another: Dyn primarily works with companies with a big web presence to improve their internet performance and Renesys’s experience providing internet monitoring information to ISPs will help Dyn better cater to its enterprise clients, including Twitter(s twtr), Zappos(s amzn), and Pandora.

Renesys’s services plug into the global router infrastructure that spans the internet, said Renesys CTO Jim Cowie, and the company constantly communicates with ISPs who need to know where and when their performance is being hampered by the many different things that can slow down internet activity or even shut it down altogether. For example, Cowie said Renesys noticed in March when the Turkish government imposed a blackout on social media sites like Twitter and YouTube(s goog) by creating a DNS redirect that caused users to be taken to a government site rather than where they wanted to go.

Dyn is more action oriented, Hitchcock said, as instead of just notifying clients when their networking activity is slow, the company provides performance plans and can redirect a client’s activity to another data center to ensure smooth connections.

Now with Renesys, when Dyn gets notified that the internet plumbing is clogged up somewhere around the globe, Hitchcock said the company can instantly address the issue faster than other services because Dyn has access to a bigger view of the internet through Renesys instead of having to rely on fragments of data.

Even though Renesys will be part of Dyn, Renesys will still provide services to ISPs, according to the two executives.

Hitchcock said the two companies casually talked about joining forces around 2 years ago but it wasn’t until February that they started cranking the wheels on the transaction.

Financial terms were not disclosed, however Dyn will be taking in all 40 of Renesys’s employees bringing combined headcount to north of 350 employees, Hitchcock said. Renesys’s office in Hanover, N.H. will become one of Dyn’s regional offices. Dyn itself is based in Manchester, N.H.
