I would have concurred on this not so very long ago, but Cogent has made =
serious strides in improving this.
In particular, I think Cogent is fairly trustworthy to at least AT&T and =
Verizon at this point.
As for Charter, Comcast, Cox, and the like, I=E2=80=99ve come to believe =
that there=E2=80=99s really no substitute for direct interconnection to =
those guys if they=E2=80=99re part of the market you serve.
My clients are mostly ISPs and ITSPs and for the over-the-top ITSPs, if =
they=E2=80=99re serving clients whose broadband access is one of the =
major cable providers, I always encourage the client to establish a BGP =
session directly into that provider (whether purchasing enterprise =
transit from them, but just accepting customer routes and advertising =
with a no-export prefix or formal paid peering, etc.)
The impact that it has on service quality is measurable and it=E2=80=99s =
a significant impact in many cases.

work with our remaining providers to de-preference Cogent completely.
