Omaha, Nebraska.  June 7, 2011.  Data center developer Prairie Bunkers LLC, which previously was solely offering rack-ready Tier III data centers, announces the offering for sale, commencing in Summer 2011, of powered "shell" DataBunkers, configured in 1MW/5000 s.f. modules for the rapidly-growing cloud computing, managed services and disaster recovery markets.  The DataBunkers are located near Hastings, Nebraska, along a Denver-to-Des Moines data center corridor selected by Google, Yahoo, eBay, Microsoft, IBM, Time-Warner, Equinix, Fortrust and ViaWest .  Prairie Bunkers Data Center Park is outside the zones for earthquakes, floods, hurricanes, volcanoes, airport flight paths and major traffic routes.   

The powered shell DataBunkers will be priced so that large users, including other data center developers, can configure a secure "campus" with multiple bunkers at a total capex and opex competitive with larger footprint sites. For users who prefer modules and footprints larger than 5000 s.f., adjacent bunkers can be connected with new construction.

The purchase price for each powered shell includes approximately 1.5 acres of land; and

* an above-ground bunker with 5000 s.f. of internal floor space, loading dock, 16 to 14-foot ceilings, openings for ventilation, surrounded by 12-inch reinforced-concrete walls able to withstand F5 tornados or terrorist attack and insulated on three sides and top by three feet of prairie soil/grass;

* 3000 to 5000 s.f. of white space for server racks/cabinets, depending upon Buyer design;

* 1MW of redundant power with over 40% carbon-free content at rates between $.05kWh to $.06kWh;

* multiple fiber providers with latency estimated at under 40 m/sec to either Coast;

* space for optional in-ground geothermal cooling system, solar or wind installation;

* paved, lighted access road, parking, septic and security perimeter; and

* consulting and assistance with local planning and permit authorities to enable 6-month buildout.

As an additional-priced option, Prairie Bunkers offers its completed design for conversion of a powered shell bunker into a rack-ready, Tier II or Tier III, high-density, hot-aisle containment, LEED-certifiable, datacenter, with an estimated P.U.E. of 1.2 and short (6-month) lead time for construction.

Prairie Bunkers also announces new power rates pursuant to its agreement with power supplier South Central Public Power District.  For users making commitments in Summer, 2011, the rates are expected to average between $.05 kWh and $.06 kWh, depending upon the load factor.  South Central's power mix includes 30% carbon-free content from hydro, wind and nuclear sources.
