Seeking Reviews of Colocation Facilities?

h_box asks: "My small company is looking for a colocation facility to host a few Apache servers and Oracle database boxes. Is there a definitive review site on the net for this type of facility? Really what would be helpful would be a review site that comprehensively reviewed candidates physical facilities, their quality of support, their network architecture, and maybe even tracked network downtime. For those of us in Southern California, it would be additionally helpful to make sure the site will stay functional throughout rolling blackouts. Don't forget financial status! We want the servers nearby, for convenience, although we are well aware that there are excellent and cheap colo facilities in the midwest."
