This is very true!
When a provider oversubscribes their resources this is called contention and it can occur in a number of different places in their network.
The majority of the contention will usually happen on their connection back to the BT RAS (the connection between them and BTs ADSL networ). The
connections into BT are very very expensive i.e. £35000/year ish for 10Mbps!!! So generally the cheaper providers try to fit as many customers into
the pipe as they can.
The second place contention may occur in the providers network is on the upstream capacity. I.E. how big a connection they have to the Internet. The
cheaper providers generally have a finite amount of capacity available so that the cost is controllable. Better providers connections are burstable
i.e. they will go as fast as is needed at any time to avoid slow downs.
P.S. IP Transit is the proper term for bandwidth. I.E. moving IP packets around the world.

Are you sure? I thought the maximum bandwidth for copper cable, ie adsl over a telephone was about 11Mbps and for cable was approx 33Mbps. Anything
more than that was impossible due to lack of bandwidth.
Edit: Just checked and maximum for ADSL is 7.1Mbps download. Maximum equivalent cable is T3 in USA which is 44.74Mbps. VDSL has a maximum of 51.64Mbps
but I very much doubt you would have this piped into your home. The maximum possible on cable is 13219Mbps but this is used for things like cable
links from one continent to another etc.

Must admit your right ( eats humble pie ). That certainly is some service. Is it cable based? To achieve that much bandwidth down copper cable is
incredible.
