Ok. Thanks for the information :) So that would mean that to answer my question, I would need to determine the web hosting provider who has the most number of peers and most number of transit providers?

Hi!

You wont see those local peerings unless all those providers have looking glasses. So thats not gonna work out in this 
case. You will only see who they transit with...

Hi.

Thanks for the prompt response.  Actually our requirement is to find a webhosting provider whose routes are widely 
advertised locally and regionally.  This is why I thought of using bgp as a basis studying the availability of routes 
of the hosting provider.

Hi!

Dont mix up peering and transit connections!

That you dont see that route on a lookingglass doesnt mean much. Only Could tell you they dont transit there.

Its all depending what you definiƫren with available routes.

If i peer with all ISP's in a specific area and your looking glass isnt licated there does that mean its bad? You need 
to know much more. If your customers are local there its even prefered.

Its never that black/white ...its depending on your needs!

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.
