This would explain the increase in complaints about capacity on Knowsley and why there's a resegmentation list as long as a Des O'Connor concert on there.
For the curious a while ago after merger a list of ports in need of resegmentation was produced for Knowsley, Langley and Bromley. Knowsley's initial estimate got laughed out of the place and they ended up doing 4 times as many capacity upgrades to resolve issues as they originally mooted. Telewest's idea of 'capacity planning' was somewhat 'interesting' and their idea of how to add capacity a bit of a bodge so as ntl:Telewest / VM were unravelling the mess it became clear more and more work needed to be done.
Ex-ntl's planning guidelines were more conservative and rather than the bodges they tended to pull the fibre and do the resegmentation instead. More scalable and permanent solution and also good for network health though far more time consuming and expensive. This meant, and it looks like it means that they take longer to deliver tier uplifts but they do it with less complaints
