I had no luck with finding reviews/opinions on Gowebman.com
I'm looking for a reliable Chicago colo, which is just as Gowebman located at Equinox. Seems like I'll go with servercentral.net as they have many positive reviews. Have you had some good experience with any other Equinox Chicago based company?
Not sure about Equinix, but I know there are some other Chicago providers including cihost and coloquest.com . I hear not so good things about cihost but I think the verdict is still out on coloquest.com - they seem good though based on some recommendations.
