Credit: Supplied The commissioner of the Australian consumer watchdog has warned National Broadband Network (NBN) retail service providers (RSPs) to keep pace with demand when it comes to how much capacity they buy from the network wholesaler. The Australian Competition and Consumer Commission’s (ACCC) latest quarterly NBN Wholesale Market Indicators Report showed that RSPs acquired slightly more bandwidth in the March 2021 quarter, which led to total Connectivity Virtual Circuit (CVC) per user increasing marginally from 2.44Mbps to 2.54Mbps.
