Thanks for the linky Rizla.
No AFAIK the FUP has never been invoked on any UKO LLU customers, although it is and has always been assumed to be around 500GB.
Re the IPStream.. TBH I'm hardly surprised.. theyre owned by the Sky empire, so with Skys IPStream equivalent being 40GB, I suppose it was only a matter of time:/
Interesting discussion going on in that thread - and good point about peak vs off peak.
Not sure about the datastream suggestion though. Afterall it doesnt work for Tiscali.. nor did it work for Bulldog. I think someone missing the point of how datastream works. Which is going to show contention sooner? - a 10MB VP at the exchange (yep that is/was the maximum size of a datastream VP) shared amongst x no of users from that exchange.. or a 622Mbps IPStream Central Pipe shared amongst the same no of users.
Contention does and has always worked like that - the more that share the bandwidth, the more variables, therefore less likely to see congestion. Its why IPStream now uses the 'Supa VPs' and why since they have, its one of the reasons why theres been less BTw IPStream congestion than the old smaller VPs that they used to use. - despite speeds now being <8Mb rather than the previous 2Mbps maximum.
