Yahoo!'s Lockport expansion gets regulatory green light

Yahoo!'s plan to expand its data center campus in Lockport, New York, has taken another step forward Tuesday, after local planning officials approved the company's site plan for the second phase, The Buffalo News reported.

Paul Bonaro, head of the company's Lockport facility, told the news outlet he expected construction of the next phase to take about one year. Groundbreaking is scheduled around 1 December.

The data center campus is famous for being the first location where the internet company used its infamous Yahoo! Computing Coop data center design. Initially called Chicken Coop, the design maximizes the use of outside air for cooling to reduce its energy consumption.

T5 leases powered shells in North Carolina to financial-services firm

An unnamed financial-services firm and data center wholesaler T5 Data Centers have secured tax breaks for a project on T5's site in Kings Mountain, North Carolina. Local county officials approved a 10-year abatement of 65% of property tax on the facility, The Shelby Star reported.

The tenant has agreed to lease half of all powered building shelves on the campus for 10 years. The deal is for turn-key data center product, so T5 now has to fit the powered shells out to the tenant's specifications.
