PHOENIX, Oct. 7, 2013

PHOENIX, Oct. 7, 2013 /PRNewswire/ --CoreSite Realty Corporation (NYSE:COR),
a premier provider of network-dense, cloud-enabled data center solutions and
the CoreSite Mesh, today announced at NANOG59 that the London Internet
Exchange (LINX) has chosen CoreSite's Northern Virginia data center campus as
one of the locations for its first North American peering exchange, LINX NoVA.
This new deployment from one of the world's leading network and Internet
exchanges, will enhance CoreSite's existing carrier density and increase the
number of options for Internet peering and customer connectivity. The
cloud-enabled data center campus in Northern Virginia, which includes
facilities in Reston, VA, and Washington, DC, supports a robust community of
nearly 150 customers, including over 45 networks and ISPs.

LINX, one of the world's largest Internet exchanges, currently connects over
480 networks from nearly 60 countries, including more than 1,100 ports.
Internet exchanges such as LINX allow Internet Service Providers (ISPs) and
other organizations to directly connect to one another to exchange Internet
traffic. LINX's entrance into the North American market supports CoreSite's
Open Internet Exchange Hub, announced in 2012 and aligned with key stated
principles of the Open Internet Exchange (Open-IX), a member-governed
organization working to drive the expansion of business-neutral Internet
exchanges, reduce internet complexity and cost, and improve access to networks
within critical interconnection markets. 

"We are delighted to be expanding into North America," said John Souter, CEO
at LINX. "We believe that our deployment in CoreSite's Northern Virginia
campus will contribute to us being able to create a successful new exchange in
the US. To demonstrate our commitment to building a world leading Internet
Exchange in North America, we will be subsidizing it by providing free 10G
ports to any networks who join."

CoreSite's open peering exchange policy gives customers best-of-breed
connectivity options through public peering opportunities in addition to
CoreSite's robust network density and customer communities. Customers are able
to access the CoreSite marketplace where network, content, and cloud service
providers, along with a wide array of enterprises, interconnect and exchange
traffic and services in an efficient, cost-effective manner, ultimately
reducing latency and improving network diversity. In addition to being able to
peer in the Northern Virginia area at LINX NoVA, CoreSite's Open Internet
Exchange Hub currently provides direct connections to multiple exchanges
including remote access to peering in Europe at the London Internet Exchange
(LINX), Amsterdam Internet Exchange (AMS-IX), German Commercial Internet
Exchange (DE-CIX), and peering elsewhere in the US with New York International
Internet Exchange (NYIIX) and CoreSite's Any2 Internet Exchange.

"The addition of LINX NoVA to our group of peering partners will further
enhance the existing network density inherent in CoreSite's Northern Virginia
community and support the development of a more robust Internet peering
ecosystem in the important Northern Virginia market," said Brian Warren, VP
Product Management at CoreSite. "As reflected by the introduction of our Open
Internet Exchange Hub last year, we believe in the importance of neutral
Internet exchanges and our relationship with LINX NoVA in Virginia further
strengthens our platform's value in providing our customers additional
opportunities for both connectivity and community."
