It looks like there is some kind of throttling on 50 meg. Maybe not the same STM as on the other speeds, but throttling non-the-less.

Virgin are a bunch of idiots. They launch 50 meg. Assuming they have more than two brain cells to rub together between them (I know, but stay with me), you would expect them to have anticipated that the early adopters of this rather expensive and allegedly "unlimited" service would be the kind of people who download a lot. An awful lot. All the time.

Their attempt to generate good publicity by initially making the service un-retarded seems to have been a massive mis-calculation. Faced with this, they are forced to bring in throttling, generating bad publicity and loosing them money as people report faults, call out engineers, kill their modems to get them replaced and eventually end up getting their bills discounted or the whole thing (including install fees) refunded.
