There was a bit of M&A that apparently came out between Christmas and New Year's this year that is worth notice. According to Fierce Telecom and an FCC Filing, Windstream has quietly agreed to acquire MassComm in an all-cash transaction.
MassComm is a NYC-based CLEC offering voice, data, and managed services with the regulatory chops in California, Connecticut, the District of Columbia, Florida, Illinois, Massachusetts, Michigan, New York, Pennsylvania, and Texas.
That's about all the information I have been able to dig up on the company (feel free to inform me further in the comments below), other than that they are obviously small relative to Windstream and have historically leased whatever last mile assets they use to reach customers.
Nevertheless, it shows that Windstream is continuing to add assets and customers to its enterprise-focused businesses even as it continues to integrate last year's purchases of EarthLink and Broadview Networks.
