I am amazed at this record, but the way things are going and being built, I imagine it won't stay a record for long. The Data Center Journal reports that CH2M designed the world's highest density data center at 500 Watts/sf!!
Since I am a Google maps fanatic I checked it out (http://maps.google.com/maps?f=q&hl=en&q=5680+Greenwood+Plaza+Blvd,+greenwood+village,co&ie=UTF8&z=10&ll=39.626846,-104.924927&spn=0.41886,1.384277&om=1)
I've always liked the Denver area and have some friends and relatives out there. Maybe I'll check it out the next time I am out there.
