Unfortunately as I found out to my own cost, DC providers are vague on these things and get away with it. If you walk into a facility that looks the part, and they talk the talk, you can be fooled into believing things are redundant or even up to spec when they aren't. The simple fact is that you have to get it all nailed down in writing or all the talk of redundancy is finger in the air stuff. Even then, asking for N+1 power feeds, and N+1 UPS, you almost need a schematic of how it’s all connected to be fully aware of the failure modes. Too much of all this stuff is marketing BS in my experience. Finally, a lot of SLAs are so weak that they find ways of getting around them, or even if you make an SLA claim, the payout in no way compensates for the level pain you will incur during down time. -Paul-
