Big Variation between ISPs for ADSL
The 2:1 spread of times taken to download websites on ADSL suggests important differences between ISP connectivity to NZ and USA websites. This is much larger than would be expected for random events.
TrueNet is looking for volunteers for our ADSL panelist pool because many of our panelists have migrated to new technologies. Upgrading is not possible for many consumers, and we want to continue measuring ADSL. If you are interested please visit our Volunteering or our FAQ page for more detail - being a panelist helps improve NZ internet performance, but also has personal benefits.
After a couple of months of very high quality copper performance from all ISPs, this month congestion is rising again. ISPs need to maintain capacity as demand growth increases over time.
TrueNet tests show a consistent under-performance from MyRepublic 100Mb/s Fibre during the busy period after 4pm. We looked at their speed performance in detail and found that it is significantly below that of Spark, for all download destinations. Further, our data shows that the sample of NZ public websites downloaded from MyRepublic 100Mb/s fibre probes takes more than twice the time during the hours of peak usage than other ISPs we measure.
Copper connections continue to be offered in NZ with a 5 Star performance. All NZ internet providers show peak period speeds on copper (ADSL & VDSL) almost equal to off-peak speeds (better than 95% of maximum possible speed). Interestingly, our panelists in Australia get 4 Stars only, with a measurement of 94%.
There was no change in specific speeds in the three months including March, April & May 2016 in spite of 9 of our panelists who had their connections updated by the Rural Broadband Initiative (RBI). Only one had a very minor change in performance.
Time of Day variations improved for all RBI funded DSL similar to that of Urban DSL seen in the May 2016 Urban report. Contention is almost completely absent in the rural RBI funded areas we test.
Another month of excellent copper connection performance by all ISPs that we measure, the best on record. This means that all major ISPs are delivering ADSL and VDSL evening speeds that are nearly equal to the speed achieved when there is no traffic - see Charts 8 & 9. Thats the equivalent of having all cars on a motorway doing 95-100km/h during the rush hour. Fantastic!
Trustpower performance improvement is impressive. After reporting their fibre performance for only 3 months, TrueNet's test results now show that Trustpower has removed all congestion. We report the combination of 50 and 100Mb/s products showing the variation by time of day, which this month is almost zero. See Chart 7A
We also see a major improvement in Vodafone speeds for 100Mb/s fibre, increasing from just 60Mb/s to a more regular 95Mb/s for most TrueNet panelists on Vodafone connections.
