Sponsored by Businesswire

CoreSite Realty Corporation (NYSE:COR), a premier provider of secure,
reliable, high-performance data
and interconnection
solutions across the U.S., announced that in April it executed a
sizeable pre-lease at its SV8 Data Center at its Santa
Clara campus

Hyperscale Pre-lease in Santa Clara

In April, CoreSite pre-leased approximately 108,000 net rentable square
feet, or about two-thirds of its SV8 data center that is under
construction, including phases 1 and 2. CoreSite expects to complete
construction on phases I and 2 late in the third and fourth quarters of
2019, respectively. The addition of this hyperscale lease complements
CoreSite’s Santa Clara campus that currently serves a wide range of core
retail, scale and hyperscale colocation customers.

CoreSite’s current development of SV8 and future development of SV9
reflect its strategy of operating a national platform of network-dense,
cloud-enabled data centers, hosting enterprises, networks and cloud
service providers to enable high-performance applications among
CoreSite’s customers.

Opportunistically Evaluating Scale Leases that
Value CoreSite’s Differentiated Data Centers

“We’re very excited to have executed this hyperscale pre-lease at our
SV8 data center,” said Maile Kaiser, CoreSite’s Senior Vice President of
Sales. “We expect to continue to pursue scale and hyperscale
opportunities for businesses who require low latency and high
performance capabilities and that value our differentiated, rich
ecosystem, located in our edge markets. As we continue to focus on our
current property development pipeline with ground up developments in
Santa Clara, Virginia, Chicago and Los Angeles, and expansions at our
NY2 and Boston data centers, we will be looking for the right scale
opportunities that complement our valuable core retail colocation
business base,” said Kaiser.

The CoreSite
Silicon Valley data center portfolio
is comprised of seven
operational data centers with an additional facility (SV8) under
construction, and a planned future data center development (SV9),
providing colocation solutions to one of the largest concentrations of
Internet and technology companies in the world. More than 250
