Another predictable episode of cut-throat business practices. http://www.theregister.co.uk/2012/12/21/bt_overcharges/
BT overcharged its rivals £95m between 2006 and 2011 - and will pay the excess back to TalkTalk, Virgin Media and others following an Ofcom probe.
There were three investigations in total: one was triggered by Verizon UK, another by Cable & Wireless and the third by an aggregation of ISPs including TalkTalk and Sky.
They all claimed that since April 2005 BT overcharged for its Backhaul Extension Service (which connects unbundled exchanges to an ISP's network) and Wholesale Extension Service (connecting bits of the network together), both of which are provided by BT for a one-off fee and ongoing rate, and it's this rate that Ofcom feels was exceeded.
Oh my what a shocker, a monopoly company abusing its monopoly, what a suprise
