Cavern Technologies Facility

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 •  Energy Efficient Green Space • 15% savings on cost of build-out • Ability to provide “just in time” data centers

Space

• Natural bunker protects from tornadoes and natural disasters •  Limestone is 3 times stronger than concrete •  Protected from flooding/one of the highest points in county • 300 miles from closest fault line

Protection

• Kansas City metro has one of the nation’s lowest cost of power (3.5 – 4.5 cents per kilowatt hour)

• Cavern has two separate power circuits into the Caves that provide redundant sources of electricity

Power

•  Tw telecom, AT&T, Time Warner Business and Surewest 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
