TrueNet noticed a few months ago that file download tests for TelstraClear Cable had wide variation in speeds during a single download, and frequently reached just 5Mb/s.
We have identified issues including the potential double impact of both not peering, and packet loss on a route between TelstraClear and our server. TrueNet's server is openly connected to both the Wellington and Auckland Internet Exchanges (WIX & APE) but these options were not used by TelstraClear.
In this issue of the TrueNet Broadband Report we measure DNS response for the first time, and Snap takes the honours in the first round. Latency tests are extended to Australia.
Telecom still has some work to do to improve Latency and Webpage Download times to catch up with the rest of the market.
TrueNet Webpage download times show Vodafone Cable as the quickest with Orcon (Fibre), and Snap (Fibre/VDSL) a close second and third in the new International comparison.
Best Speed consistency is with Snap(ADSL & VDSL), Orcon(ADSL), Slingshot(ADSL), Voyager(VDSL) and Telecom, all better than 95%. The best Fibre speed, Snap's 100Mb/s service, is just 93% of advertised speed.
Two ISPs, Orcon and Snap, successfully achieved significant improvements to performance for their DSL customers in direct response to TrueNet monitoring. They found the cause of frequent delayed downloads of our New Zealand test webpage creating two typical download times, 0.5s and 2.0s, and reduced the frequency of the 2s downloads.
Snap achieved the change in May and Orcon in June.
The May TrueNet results show competition between ISP's to deliver the best broadband experience is intensifying.
Last month we were able to report fibre performance for Orcon, this month we have sufficient tests to report results for Snap. ISPs across all technologies are now reporting better than 90% peak to off-peak speed performance.
Slingshot had a major improvement with speed performance coming in 3rd this month after being last in April. Snap significantly improved Webpage performance with changes they made in early May.
The government sponsored fibre installation project (UFB or Ultra Fast Broadband) is very much faster at downloading webpages than other technologies in New Zealand.
Fibre performance from the UFB rollout is reported for the first time with TrueNet having a good sample of Orcon UFB connections.Overall Performance
UFB is an alternative to the standard ADSL service that all ISPs offer, and is best compared with Cable and VDSL services. Orcon's 100Mbps service is significantly better than either VDSL or Cable, while its 30Mbps service is a little better than both VDSL and Cable.Webpage Downloads
Only UFB Fibre provides a consistent technology for webpage downloads, with both Orcon's services achieving excellent results. VDSL performance is significantly better than ADSL with Snap and Voyager beating TrueNet targets, while only Snap achieves better than 95% in ADSL. Telecom's ADSL is very close, only dropping below the 95% after 3pm.Latency
Voyager is joined by Snap in achieving best National Latency figures in April. Large differences in International Latency between ISPs are significant in affecting the performance of voice and video services requiring always-on connections.
This monthTrueNet reports ISP performance across fixed line technologies using: Speed by Time of Day; time to download a Webpage; National, International, and regional Latency.
High Latency across an ISPs network can result in failure to download a webpage or delays in real-time traffic, but might not show up in TIme of Day and Webpage download results.
Thanks to funding from the Commerce Commission, TrueNet's monthly reports are more comprehensive than ever before. To enable a quick understanding of our research analysis we start with a summary of our results.
Of the six ISP products that achieved TrueNet’s speed performance target of 95% in January, only Orcon Capped sustained that performance to achieve the target in February.
Telecom speed performance fell for the first time, TrueNet understands that Telecom had a "network issue that has since been resolved".
Slingshot improved their unlimited plan performance to better that of many capped services, including their own capped service. "In February our Unlimited customers were the first segment of our customer base to be migrated to our new high capacity network core"
