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.
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.
In this quarter there is a trend for some ISPs to have exceptionally large latency. This is caused by the very long path that data is sent on its journey to Sydney or Melbourne from New Zealand (via Hong Kong, or LA); and from the UK to New Zealand (via Hong Kong, then USA). At present, traceroute monitoring from our panelist's connections show the problem lies with Vodafone and 2Degrees, with Voyager caught up in similar delays due to their use of Vodafone's international connections.
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.
The continuing development of internet connections in the latest quarter has seen consistent improvements in performance. The Rural Broadband Initiative (RBI) is growing by about 7% per quarter, these improvements are from wireless connections over Vodafone's 4G mobile links or Chorus' fibre to rural cabinets.
This quarter, Wireless RBI performance has reduced in the evening busy hour, but with higher speeds, this may not be noticeable.
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.
ISPs connected through UFF continue to provide performance well above their advertised rate for the 100Mb/s services. At lower speeds, such as 30Mb/s, there is no substantial difference between LFCs for peak speeds. We report that almost half of TrueNet's panelists' using the 200Mb/s services consistently achieve better than 200Mb/s downloading from the Internet.
