DENVER, June 5, 2013 /PRNewswire/ --CoreSite Realty Corporation (NYSE: COR),
a premier provider of network-dense, cloud-enabled data centers and the
CoreSite Mesh, today announced that SunGard Availability Services has deployed
at CoreSite's facility in Boston. SunGard Availability Services, one of the
world's leading providers of information availability and disaster recovery
services, is seeing expanded business opportunities in the New England region
targeting leading heathcare, financial servces, retail and IT Services
providers and selected CoreSite as a service partner to support this growth
through a flexible, scalable data center solution for its customers. The
agreement gives customers the combination of top-tier managed IT services from
SunGard Availability Service and high-powered data center capacity, diverse
network connectivity and CoreSite Mesh community members from CoreSite.

As a result of CoreSite's data center capacity in Boston, combined with an
extensive carrier network (over 70 networks and more than 20 carriers and
Internet Service Providers), SunGard Availability Services was able to quickly
deploy nearly 10,000 feet of capacity as a turnkey data center solution for
its customers. SunGard Availability Services' customers will immediately
benefit from the improved application performance that comes from directly
connecting to multiple networks, including connections to sub-sea cable assets
providing a gateway to Europe, and the on-demand capacity available to augment
their own data center resources.

SunGard Availability Services has seen strong growth in several of its key
vertical markets and critical aspects of the CoreSite model will enable
SunGard Availability Services to capitalize on that market growth in the
Northeast region. Financial services is a focus for SunGard Availability
Services and the proximity of the Boston facility combined with network
density were important considerations given the latency and application
performance requirements common for financial institutions. Additionally,
CoreSite has achieved 99.9999% uptime, which addresses the critical
reliability requirement necessary for SunGard Availability Services'
customers, particularly in the growing healthcare vertical. Retail is also a
focus for SunGard Availability Services' growth strategy and CoreSite provides
the robust customer community needed by SunGard to capitalize on the expanding
opportunity. All of SunGard Availability Services' customers will benefit from
taking part in the CoreSite Mesh, the community of service providers and
enterprises interconnecting in and through CoreSite's cloud-enabled data
center campuses.

"As our customers' requirements continue to grow and expand, we strive to
provide them with best-in-class solutions," said Jack Dziak, EVP and General
Manager, SunGard Managed Services. "CoreSite brings premium data center
capacity and the diverse network connectivity that our customers across

application performance requirements."

"We are pleased to have SunGard Availability Services become a member of the
CoreSite Mesh community, helping support the growth of their business and that
of their customers, while also bringing one of the world's leading managed
service providers directly to our customers," said Jarrett Appleby, chief
