Split Node

I am interested to hear about split node as well. I literally had a tech at my place on Saturday last weekend who told me the network is overloaded on my node. No amount of line boosters, modem, gear, or anything would correct that problem. Ive been battling this for two years now myself and have invested hundreds of hours into phone calls with tech support (complete waste of time, do not call them with complex issues like this), trying different line boosters, modems, routers, you name it. At the end of the day its my node and cox's network which is unable to handle the volume of traffic on the node due to over selling bandwidth in the neighborhood. Essentially Cox has adopted the airline model, oversell everything and pray you are not the guy that checked in late online and now lost your seat.
