35. Cavern Technologies Facility

39. Cavern’s Underground Facility = Competitive Advantage
Offering one of the best combinations of available secure space,
power and connectivity in the country.
• Options over 300,000 square feet
Space • Energy Efficient Green Space
• 15% savings on cost of build-out
• Ability to provide “just in time” data centers
• Natural bunker protects from tornadoes and natural disasters
Protection • Limestone is 3 times stronger than concrete
• Protected from flooding/one of the highest points in county
• 300 miles from closest fault line
• Kansas City metro has one of the nation’s lowest cost of
Power power (3.5 – 4.5 cents per kilowatt hour)
• Cavern has two separate power circuits into the Caves that
provide redundant sources of electricity
• Tw telecom, AT&T, Time Warner Business and Surewest
Connectivity underground fiber cables enter the below ground facility
from five diverse routes
• Provides the option for total redundancy for SONET based
services and Telco Central Office diversity
