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%.
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.
This month we compare webpage download speeds with those reported by the FCC (USA's equivalent of the Commerce Commission), who use nearly identical methods to TrueNet. In New Zealand, ISPs performance in copper delivery is far superior to that of their counterparts in the USA. The worst NZ ISP is well ahead of the best USA ISP for Time of Day performance.
Another 100% result, this time from first time reported Voyager 100Mb/s fibre panelists, who saw the 100Mb/s advertised speed or better at all times of day. There are now four broadband products where actual speed during March was faster than advertised speed at all times of day. These are:Vodafone 100Mb/s Vodafone 50Mb/s cable Voyager 100Mb/s fibre 2Degrees 30Mb/s fibre
Performance for all other products remains similar to previous months, continuing the trend of ISPs responding to having their performance tested and published continuously.
Higher speed services, 100Mb/s and above, are showing signs of congestion for panelists on smaller ISPs, evidenced by speed reductions in the evening busy hours. Larger ISPs are still performing well, and appear to have congestion under control.
NZ website download times increased across all 2Degrees technologies compared to January, despite staying the same for Australian websites.
Spark 100Mb/s panelist tests have reached a sample size large enough to be reported separately, they have until recently been include in "Other ISPs". Spark results were better than many of the smaller ISPs, so "Other ISPs" as a group without Spark panelists now show a worse result.
Flip delivered an extraordinary result for their ADSL product, with their peak NZ download speed being equal to their off-peak speed, meaning no congestion at all. They also managed an excellent website download result.
January 2016 saw little change from December 2015, but some ISPs are reaching their capacity limits again with a little bit of congestion showing.
We include Voyager VDSL again after a long period without sufficient panelists. They performed very well in downloads, less so when retrieving a webpage from Australia.
Chorus have been busy upgrading Copper based VDSL to deliver even faster speeds to most customers, independent of ISP. With the introduction of a new band-plan (technical term for changes to the frequencies used) completed in early December, a number of VDSL users will have experienced improvements in performance throughout December and January because the exchange part of DSL technology takes time to discover how to distribute the gains to users.
Performance continues to remain high from all our major ISPs, especially on upload, suggesting the NZ network is free from congestion at this point.
After four years of monitoring broadband technology TrueNet's impact on the quality of performance across all products and technologies is now obvious, as all ISPs that TrueNet reports on are achieving the targets we have set. Congratulations to the major ISPs for reaching a successful product performance standard. We will continue to monitor to ensure that standard is maintained.
We monitor a small sample of Australian connections, and their performance remains below that of all NZ ISPs with the exception of the obvious - downloading of Australian websites.
Congratulations should be extended to the Commerce Commission for having the foresight to start the process; to Vodafone and the Commerce Commission for purchasing our data, making it possible to continue publishing.
Performance of Vodafone 100Mb/s Cable download is now equivalent, if not better than competitive 100Mb/s UFB fibre services. On October the 2nd, Vodafone Cable fixed their major network problems that have been evident since March (NetFlix launched it's services in March) when speeds dropped from 110Mb/s to below 5Mb/s for many users.
Other improvements include reduction in congestion on almost all remaining products and suppliers, to a level not seen before as ISPs are clearly investing in sufficient capacity to meet demand. Orcon, MyRepublic and some Other ISPs have more work to do, but all have improved.
Copper services show a very different trend with Vodafone now requiring more investment to resolve congestion after months of good performances, and Slingshot continuing their major improvement from last month to now lie within the leading bunch of ISPs.
