BGP Peers as basis of available routes

["Nathanael C. Cariaga" <nccariaga () stluke com ph>]

Hi!

We're currently evaluating web hosting providers in the APAC region and 
one of the criteria that we are currently considering is the 
availability of routes going to the web hosting provider.

In this regard,  I would like to ask for your idea regarding this.  Is 
it safe to conclude that the web hosting provider's available routes 
would would depend on the peers who are advertising their AS / network? 
 (i.e if web hosting provider claims that they are peering with telco 
a, b, c but as seen from a third party looking glass, only C is seen 
advertising the web hosting provider network that would mean web hosting 
provider is effectively utilizing c as their upstream??)

Thanks.
