Check my math
On the page that describes the "Chicago Data Center, Building Spec, Physical Structure" is listed as 10 000 sq ft.
If I rent one of the 100' x 100' Private Data Vaults per the available colocation spaces listed, that is also 10 000 sq ft, so they would not have enough space left over for a 1U machine. Much less any of the other spaces that are mentioned for rent. Or space for an office, a 24x7 guard, 24x7 on-site technicians, another 100' x 100' Data Vault, or anything along that line.
One of the features they mention is "Constant n+1 ambient air temperature of 68° (+/- 5°)", huh ? They also have "Internal and external cooling units", so they must cool Chicago, Wow!
100% Service Level Agreement - impressive, very impressive!
Or under building structure they have - "Line of Sight: Clearance of the roof is to the East, all other directions are blocked by surrounding buildings", but if you are looking for roof space they have: " Available for tenant's mechanical and technological communication needs; building has a clear line of sight in all directions", nice trick. (and are smoke signals a mechanical communication need?)
But if you need it they do offer, as a "Business Convenience ... Internet connectivity" always a good feature in a data center.
I also note that the Manhattan, NY, facility, which is not in Manhattan, or New York, for that matter,(notes below) is "our newest state-of-the-art data center", for ease of access they offer, not some claustrophobic elevator, but instead, a "single flight of stairs with no turns". And when you talk about any facility in "New York", you simply CAN NOT say, that it is " built to ensure ... continuous operations - even in the event of severe... man-made catastrophes", it is just bad for your credibility.
Other than that and a number of similar examples, the place looks good. But if you post things like the above of your website, your credibility for any other claim, just can't carry much weight.
The Manhattan data center is listed as being in New Jersey,but it is touted as being located 8 miles from the heart of Manhattan. Manhattan consists of at least 6 islands of 'habitable' size, and a hunk of 'mainland'.
The Statue of Liberty is on an island in Manhattan.
Part of Ellis Island is in Manhattan also, it is also part of the Census location of, New York, New York. The 'natural' part of Ellis Island is in Manhattan in in New York. The landfilled part of Ellis Island is in New Jersey. The fill was done on all sides of the natural island, so, at this place, New Jersey completely surrounds New York. Sorry I digress. This was intended to highlight the lack of knowledge that C I Host shows about their location.
