Underperforming broadband services are still a problem for some consumers, with a newly publish report revealing that 12.4% of consumers continue to experience underperforming services that “rarely come close to reaching their maximum plan speed”.

Most NBN users experience less than one outage of 30 seconds or more a day, but Optus customers on average had to suffer through more than 1.5 outages each day, according to the Australian Competition and Consumer Commission's fifth report on NBN speeds.

Fixed-line NBN customers are benefitting from competition among Internet service providers to perform well in the ACCC's speed tests, though some consumers continue to get much lower speeds than others on the same plan.
