Their CoLo space is the same space shared by AOL and a few other big name tech companies. It's right next to the Greenway, just before you reach IAD going northeast. That CoLo facility seems pretty unreliable in the scheme of things; Verizon and Amazon both took major downtime this summer when a pretty hefty storm rolled through VA[1], but AOL's dedicated datacenters in the same 10 mile radius all experienced no downtime whatsoever.
