Sorry for being imprecise.  I meant that adding Cogent does not  
significantly improve your reachability.  Choosing to buy from Cogent  
because they depeer / get depeered occasionally is silly, IMHO.

To be clear, I am making no comment on Cogent's overall performance.   
If you find value in adding a provider for other reasons (cost,  
performance, etc.), I would not argue against it.
