(Telecompaper) Colt has introduced a new pledge to provide customers in 20 European cities with at least 1 Gbps. The '1Gb Always' commitment will see all existing and future customers provided with a 1Gb bearer circuit. This means that no matter what speed they start with, bandwidth can be increased as required with no upgrade costs. The initiative is being rolled out with immediate effect in 20 major cities across Europe, including London, Paris and Frankfurt. All other territories can still experience rapid bandwidth, at a lower ceiling of 600Mbps as standard, with 1Gbps available on a more selective basis.
