1. CNA Data Center
Aurora, Illinois
Four years after the construction of their data center, CNA Insurance saw more
opportunity in colocation and cloud services than owning their own data center. By
entering into a sale-and-leaseback agreement with ByteGrid for their 36,000 sf data
center space in Aurora, Illinois – a transaction orchestrated by Studley and ESD
Consulting - they are able to save on maintenance costs while focusing on their core
business. CNA remains the primary tenant of the facility with 30% of the data center
space.

2. The data center facility was originally designed by ESD in 2007 and is generally
regarded as one of the premier enterprise data centers in the Chicago market. The
70,000 sf facility contains 36,000 sf of Tier III data center space which utilizes a system-
plus-system electrical design that does not have any single points of failure. It also
features a 24x7 network operations center (NOC), a NOC war room, an emergency
response room, and an executive conference room.
