MSNBC reports that Comcast has begun cutting off customer’s internet access for exceeding bandwidth limits.  Comcast reasons that excessive downloaders hog Internet capacity and slow down the network for other customers.  

Comcast refuses to reveal the actual limits before a disconnect occurs, nor how many people have been affected by the cut-off policy.  

Other Internet service providers, including Time Warner Cable, Verizon and AT&T, say they reserve the right to manage their networks, but have not yet suspended service to subscribers.
