International colocation Equinix has completed its sale of 16 data centers across the US for US$75m.

The International Business Exchange data centers, branded because of their “robust interconnection ecosystems”, have been sold to a US investment group made up of 365 Main, Crosslink Capital, Brightwood Capital and Housatonic Partners.

The investment group now controls the operations for Equinix customers previously in these facilities, and the staff that used to operate them.

365 Main is a data center developer and operator that has a 136,000 sq ft LEED certified data center in the heart of Silicon Valley.

The 365 Main Neward data center is its sixth facility – it sold five other data centers for US$725m in 2010 to Digital Realty that sat under the 365 Main portfolio.

They cover nine markets, including Indianapolis, Nashville, Phoenix, Pittsburgh, Tampa, Buffalo and Cleveland.

Equinix President for the Americas said the sale means Equinix now operates in seven markets – Chicago, New York, Dallas, Reston, Seattle, Silicon Valley and Philadelphia, which the company will focus its efforts on.

“By divesting these data centers in non-core markets, we can focus our capital and management attention on our most productive data centers while ensuring that customers at these sites are supported by an experienced data center operator that will continue to invest in these locations,” Meyers said.

Back in September, when the proposed sale was first announced, Equinix said the data centers made up just 2% of its annual revenue.

It said then that the financial results derived from the same will be reflected as discontonued operations in its earnings reports.
