Share your experience (question about Colocation)

Greetings

I begin to dig a new glade, and I have a completely new task for me to rent space in the racks in the data centers. The essence (salt) is that it is necessary to do it all over the country, that is, there are 10 servers, and you need to install them in 10 data centers in different cities of the country.

The first thing that comes to mind is Rostelecom.
')
And the second?
Who else has the resources for such a solution?

Give advice, share your experience, and maybe a good contact, who can help solve the problem?

and in principle, is it implemented centrally, that is, with the involvement of only one partner?

If the answer is on the surface - just throw a link to me.

thank
