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.
To be fair, the entire region was decimated by that storm. I didn't have power for 5 days. Much of the area was out. There was a ton of physical damage. That's not excusing them, they should do better, but that storm was like nothing I've experienced living in the area for 20 years.
