Yes, thanks to Mark for replying. This additional information makes me less likely to attribute the blame to Quicksilver for these problems.

1) We currently have a project underway to increase our Private Virtual Circuit (PVC) size from Telecom to manage future forecasted growth. Telecom controls the dimension of this PVC and constrains its size to 24kbit/s

per customer.

...

Yet at the same time, customers of Ihug, Iconz, Orcon and Xtra are all able to get much higher rates...

With this service limitation I can easily see how Quicksilver could potentially be affected more than Ihug, Iconz, Xtra and Orcon. I would guess that the average user profile on Quicksilver would tend towards higher bandwidth usage whereas the typical Xtra (etc) user would probably use less bandwidth. Unfortunately if this view I have is correct then I don't see an end to problems unless either the average Quicksilver user profile changes -or- Telecom changes the PVC limitation. -- Regan
