Impact of underperforming services on download speed2


[2] A service is classifed as underperforming if over 95% of speed tests conducted achieved less than 75% of the maxmium plan speed.

Average NBN and ADSL download speeds by hour of day

Distribution of download speed tests, by percentage of plan speed3


[3] This chart shows the proportion of download speed test results for NBN plans that were above 90 per cent of plan speed; between 50 per cent and 90 per cent of plan speed, and under 50 per cent of plan speed. ADSL results are excluded.

Technical quality measures

Technical quality measures includes web page loading time, latency, and the frequency of packet loss.
