I have had high speed cable service for a while now, very fast (15 mb+ download). The company recently sold out to Comcast, and now I find I'm getting 2 mb/sec up and down! They are throttling my service! I wonder if it is becuase I use it all day long? I haven't noticed any effect on trading. I'm just curious if anyone else has these issues with Comcast. Next thing you know, they'll be billing by the GB.
