Colocation services?

[Rock]

Hello!
In your opinion what is the best provider for colocation services?
I'm checking here:
https://corespace.com/colocation/

Are they good enough for that ?

Have as look at plans from hostingsource.com and qhoster.com. Always quick responses to any of my needs! Technical assistance has been great.

As a nice alternative, can also draw your attention to Tzulo.com colocation servers - good pricing and features included. You'll be pleased
