DENVER, June 10, 2013 /PRNewswire/ -- CoreSite Realty Corporation (NYSE: COR),
a premier provider of network-dense, cloud-enabled data center solutions and
the CoreSite Mesh, today announced a new, industry leading solutions launch
with tw telecom (NASDAQ: TWTC) that will help enable customers to connect to
cloud services with greater speed, security and flexibility.

A leading national provider of network and managed services, tw telecom will
link its industry leading Business Ethernet services platform to CoreSite's
Open Cloud Exchange, providing enterprises with dynamic private Ethernet
connectivity into CoreSite's data centers and the CoreSite Mesh. This
relationship will allow customers to instantaneously add and expand bandwidth
capacity on the tw telecom network, enabling elastic connectivity to cloud
providers in the data center. This capability will further evolve to include
tw telecom's future Constellation Platform^sm which will enable customers to
"click and connect" with Dynamic Connections, building new private Ethernet
network connections on-demand.

With today's announcement, tw telecom has completed interoperability testing
between its network and CoreSite's Open Cloud Exchange. This new capability
will enable enterprise customers to leverage best-of-breed cloud providers
within CoreSite data centers, giving them a predictable, secure and dynamic
connectivity solution not currently available today. CoreSite and tw telecom
are committed to evolving this capability further to provide a high degree of
automation that will enable both data center customers and their applications
through a combination of network, APIs, and cloud exchange, delivered as one
complete solution.

"Our combined development and operational capabilities bring business-grade
connectivity to the world of cloud solutions," said Graham Taylor, senior vice
president of marketing for tw telecom. "We will be enabling 'click and
connect' capabilities in the CoreSite data centers so customers can
immediately access the network when and where they need it."

"Relationships with companies like tw telecom help CoreSite bring its
ecosystem of solutions to our customers and address the pain points associated
with cloud connectivity," said Jarrett Appleby, chief operating officer of
CoreSite. "We believe combining our Open Cloud Exchange and tw telecom's
Business Ethernet services platform with its future Constellation Platform^sm
brings unique network, data center and cloud service ingredients together for
our combined customers."
