[graf_von_anonym]

From my lofty vantage point in Castell Anonym I can say that (in my admittedly limited experience) I have not yet seen more than about 3% of subscribers on any given CMTS traffic managed on any given day. I would say that my lofty vantage point is entirely unscientific, however, and should be taken with a pinch of salt.

The whole 'limit' thing is a marketing nonsense. When Virgin describe themselves as 'unlimited' what they mean is that there isn't an entirely arbitrary* download limit, but a bandwidth restriction. $BANDWIDTH x $TIME will always give you a maximum theoretical downloadable amount, Virgin just modify those values from time to time.

The business of running to OFCOM is, to my mind, just continued escalation from "I am going to cancel unless..." and "I want to talk to a manager". It's a product of frustration, because processes and procedures have not perhaps been clearly explained or understood. In the grand scheme of things I'd be overjoyed if I the thing that concerned me most was that sometimes my broadband were slower than at other times.

*I mean, yes, it is arbitrary in that it's a fixed amount less than the theoretical maximum, but it's probably been worked out with all manner of cunning. Ultimately I blame the conflation of bandwidth and speed.
