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...

Thanks,

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??)
