Yes. Simply contact your dedicated account manager to arrange the upgrade. It takes around 20 working days to increase the bandwidth from the point of order. The only exception to this is when you need to upgrade from a 100 Mbps bearer to a 1 Gbps bearer. A 100 Mbps bearer cannot supply bandwidth above 100 Mbps, whereas a 1 Gbps is a much thicker fibre line that can supply whatever speed you choose, up to that maximum of 1 Gbps.
