Truenet probes are always measuring performance so it is no surprise that we have the data to identify the overall performance.

While there was definitely an impact - our charts show clearly the size of the impact, it has to be called a success. - see our report here  https://www.truenet.co.nz/articles/telstraclear-unlimited-broadband-experiment-successful

The impact on individuals of a slowdown like this is real, but not universal.  This was a trial and some delays were announced and expected, hence my attitude towards success.  Realistically, loss of service was not apparent, our probes continued to work without consistently hitting the time-out and in fact got good speeds, even to the States, just not the 15Mb/s cable users are used to.   The apparent inconsistency with respect to ToD concerns expressed last week is because for evening peak periods, we expect performance to be "Normal" and a shortage of capacity causing slow-down should not be accepted, but some slowdown during a special weekend seems OK to me.

I reviewed one test at 8pm on Saturday (when the minimum speed was recorded) and it shows that this probe had no timeouts in the critical web-page or throughput tests, only timeouts occurred during traceroutes and Jitter tests to our servers, ie the longer running tests.  Timeouts were also apparent when the network was unavailable due to the volunteers usage - maybe due to the popularity of the weekend?

what about the hassles caused to Snap over the weekend, i would love to see the truenet data from Snap probes over the same time period , i know my ping doubled over the weekend on Snap.




Common sense is not as common as you think.

Hi John - I find it interesting that you characterise the TCL free weekend as a success...

"TrueNet's interpretation is that TelstraClear's experiment with unlimited broadband was a success with average speeds ranging from 3.3Mb/s to 7Mb/s with a limited number of outages."

Without mentioning the fact that web browsing and downloading aren't the only use cases for an Internet connection.

In all seriousness, were your probes able to profile the variation in latency (if any), packet loss and where it occurred etc?

Cheers - N

Here are my TrueNet data collected over the weekend: 

 

 

 

Note between 2nd Dec 6pm and 3rd Dec 11am was when my DOCSIS3 modem was out of action, replaced with new one.

Are those DNS response times really in the thousands of seconds or is the scale wrong? :)

I characterized it as a success based on a reasonable assumption that speed slow-downs were pre-announced, but the network did not fall over, just slowed down.  For Cable customers that slowdown extended from a lot to an extreme level for Mauricio (thanks for publishing your charts) What you cannot see from Mauricio's chart is that the speeds he experienced were the same as all TelstraClear customers, ie he lost his 100Mb/s premium service - not good, but I understand it may not come with an SLA :-)

What I cannot show is the one ADSL probe that had absolutely no impact.  The speed remained dead constant throughout the weekend - TelstraClear's own LLU?

We do have latency data, but unfortunately my time has not enabled me to run the analysis, maybe  later today or later in the week.

There is my connection through Snap ADSL for international latency if anyone is interested. All my other graphs remained normal over the whole weekend. Hopefully John posts a graph for all Snap users.

Given the the massive latency/response time increase, how can you claim this is a successful weekend.

If anything it shows that they didn't manage traffic well enough by reducing throughput in order to maintain decent quality of service.

Mauricio, can you post the domestic and international ping graphs for your connection?

Trawling through a few Latency charts for a quick view, apart from the issues as above, a really interesting one was one of our very few UFB probes:

 

We would love to have more UFB probes - volunteer on our site at www.truenet.co.nz

On stuff.co.nz they saying total data use for the free weekend was 359Tb compared to 216Tb from the previous weekend, Cable alone amounted for 232Tb

"TelstraClear says its 200,000 internet users downloaded and uploaded two-and-a-half times as much data than usual last weekend when it offered unmetered broadband.

Customers consumed 359 terabytes (Tb) of data, up from 216Tb during the prior weekend."

Since when does 216 * 2.5 = 359?

Absolutely par for the course with NZ media... I see very little evidence of anything more than editing press releases together most of the time. We're lucky that customers didn't download "an order of magnitude more" than usual.

Maybe they simpy typoed and meant 539TB instead of 359TB... 216 * 2.5 is almost exactly 539 :-)
