There are of course a lot of facilities missing, but every week new ones are being added and everyone are welcome to contribute by submitting data centers through the form at the website (located here).
Good information. I am sure this would have help many. And most of the guys do not have much knowledge on data centers. This will slowly gain momentum in the third world countries. Because most of the locations are in the developed countries. This situation should change.
