mpapet writes to ask about the ins and outs of datacenter evaluation. Beyond the simpler questions of physical access control, connectivity, and power redundancy/capacity and SLA review, what other questions are important to ask when evaluating a data center? What data centers have people been happy with? What horror stories have people lived through with those that didn't make the cut?

Well first of all, I don't know that I'd write any of those things off as "simple". But some other points worth looking into would be:
Cable Management (over or under floor)
Cooling Capacity and Redundancy
Power Quality (not just redundancy)
Age and Condition of Electrical Hardware (ATSs, STSs, UPSs, Generators)
Outage/Uptime History
Fire Suppression System and Smoke Detection System
Maintenance records

History (Score:3, Insightful)
Look at a datacenter's history [recent and past], outages, maintenance issues, customer support, management and etc, in conjunction with their listed redundancies and capacities.
Just because they have two electrics going to each server, doesn't mean a random maintenance tech will flip the wrong switch. :)

Involvement of the owner in the current business.
Number of years the current owner has been in this business.
Also do a check with the Better Business Bureau to see what, if any, complaints had been filed.
And, as always, Google is your friend -- definitely do a search for the business you are considering along with the word(s) problem, issue, complaint, praise, etc!

Add to that:
-KW deliverable to each rack
-Ambient temperature in the cold aisle and how closely it's held (and possibly make it part of SLA)
-On site technicians (and/or security) and their hours
-Customer access policy and applicable hours (are you going to be happy, AND are threats going to be kept out?)

Find someone you trust who's already a customer. Word of mouth beats any number of white papers or studies or guarantees.

You forgot a few:
- Enough qualified *on site* staff 24x7 to deal with all clients including yourself
- 24x7 phone support, with people who understand English and have immediate access to the techies
- Company financial records and history (You don't want someone almost broke or a new startup with no backing)
- These days availability of virtualisation solution and supporting hardware (depending on your application, if virtualisation is an option)
Oh and your emphasis on maintenance records may be a little misplaced. They can be faked. They also may not be available due to security concerns (of their other clients). *IF* you can get hold of them they should be complete. Hardware service level should be part of the agreement and service schedule should be part of that.
Step #1 = DEFINE YOUR NEEDS (Score:3, Insightful)
I'd guess 90% of projects fail at step #1: Define your needs. What's the objective here? Why are we doing this, and what are the benchmarks required for success. Does this sound familiar?
First, define your needs, then evaluate possible solutions to what might meets your needs.
If you don't know what you need, you don't know what the hell you are doing. Hire someone who does, like a consultant.
