Low Latency Networking Across USA

I have a project which requires low latency access to cable/dsl providers in USA.I need recommendations for virtualized(LEB and non-LEB) and dedicated server providers which are hosted on datacenters which have low latency upstreams(directly peers preferred) to most used cable/dsl providers like comcast, time warner, cox, charter, cablevision, at&t, verizon, centurylink, frontier etc.
