The high-dollar ones aren't necessarily better. At a previous job we hosted with {HAL} out of Atlanta. A NOC operator there saw/heard/smelled something that indicated to him that he should hit the Big Red Switch. So he did. This removed power to every machine in that part of the DC. After management confirmed that there was no life-threatening emergency, they started bringing everything back up. Only to have machines start going down again 20 minutes later, as their local UPSes ran out of juice. Someone had to walk around to every cage and recycle them all manually.
