GX Networks, the business connectivity division of UK ISP the Internet Technology Group, has signed a deal with Fibernet Group Plc to extend its national infrastructure. The three-year deal will give GX access to three super points of presence POPS and a further 30 POPS. Combined with existing arrangements with other infrastructure suppliers, it will provide GX Networks with a total of 400MB of infrastructure capacity in the UK. The deal signals an aggressive drive by GX into the business market. GX says the deal will give it access to a national network at significantly lower cost and enable it to offer a national service to corporate customers on increasingly competitive terms. Fibernet claims it has built a network that rivals that of Energis Plc, for around 1% of the cost and claims to be way ahead of its competitors in pricing and technology.
