same here. no b/w reports. Maybe IBurst have realised they can make more/faster 'fake' profit by not letting customers keep a sharp eye on their b/w usage - and presumably shaving off customers own b/w storage - so that people hit their caps faster (and thus will hopefully purchase extra b/w faster, or be switched sooner to the cheaper (for IBurst) 64k pipe..?)
I've been fed the story from IBurst insiders that out of an alleged 6000 subscribers, there's only between 20 - 60 'power users' - everyone else is supposedly quite happy.
(Note my use of the words 'I've been fed the story' - as just coz I'm told this unofficially, doesn't mean its actual truth.) Statistically speaking, this figure is unlikely to be reality.
