ABRY Partners in conjunction with Berkshire Partners LLC acquired TELX from GI Partners, which also owns ViaWest. (I have to ask why they didn't merge those two together?)  ABRY Partners has been active in telecom, buying RCN/Sidera, but especially in the data center space: spending almost $1.5B on the likes of CyrusOne, Datapipe, Hosted Solutions, Q9 Networks and Sentrum - and now TELX. (Hosted Solutions was sold to Windstream and Cincinnati Bell acquired CyrusOne.)

TELX has 15 data centers (including 56 Marietta in Atlanta, 60 Hudson in NYC, and 111 Eighth Avenue also in NYC) with 900 customers and about $129M in revenue in 2010. It filed for a $100M IPO in March, 2010. 

This is just a change in private equity holdings. ABRY also has stakes in wireless (JAB Broadband, Hometown Broadband), CLEC  (Grande), PCO (Home Town Cable) and in IT.

In other news, Earthlink "has successfully acquired Business Vitals, a national provider of managed information technology, security and professional services based in Columbia, South Carolina," according to TMC. ELNK gets a Tier IV data center out of the deal plus some Managed IT staff.
