Behodar: "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?


I presume that it was misreported. It was probably 359Tb more than 216Tb = 573Tb total. If so 573/216 = 260%

Found the correct stats on NBR. Usage up *by* 216 TB, so it went from 143 TB up to 359.

JohnButt: 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 :-)
 


Hi John,

Do you mind posting up graphs showing performance for  ISPs, Snap, Maxnet and Unleash. Those ISP's purchase transit from Telstraclear in varying percentages and we've heard reports of them being affected by the weekend stunt. While Mauricio may not have an SLA, I'm sure those providers do.

I'd really like to see the results as I believe you'll change your verdict to unsuccessful ;)

TelstraClear puts broadband weekend speculation to rest06 December, 2011
TelstraClear's unmetered broadband weekend can be counted a success after customers took advantage in a frenzy of up and downloading. Customers used two and a half times more data overall than the previous weekend. Total usage was 359 terabytes (TB), 216 more than the weekend before, and enough to completely fill 216 large computer hard drives.The greatest data benefit was to customers on the TelstraClear cable network, with total data they used being three times more than the previous weekend, jumping from 76 to 232TB.

Independent internet organisation TrueNet called TelstraClear’s weekend “successful”, saying “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.” www.truenet.co.nz/articles/telstraclear-unlimited-broadband-experiment-successful

“We expected customers to take advantage of this opportunity and were upfront from the start. We said ‘With lots of people online for longer, some customers could experience slower than normal connection speeds’,” says Steve Jackson, TelstraClear head of consumer markets.

Comparing data used over the same period a week before the unmetered weekend shows that ADSL customers used almost twice as much data during the unmetered weekend. TrueNet found that ADSL speeds dropped by “almost 40% for ADSL customers” with TelstraClear figures showing these customers also used 88% more data (126TB, up from 67). Cable customers used more than three times as much as they normally did (232TB instead of the normal 76, being 205% more).TrueNet noted that speeds dropped “64% for cable customers”.

“We made substantial increases in our national and international capacity before the weekend, and put further capacity in place when the demand exceeded this. We acknowledge that some customers were unhappy with their internet experience, just as we note that many have reported they didn’t mind slower speeds because they were able to use far more data than they otherwise would, some reporting downloading more in the weekend than their entire monthly cap of 30GB.

“We will analyse the feedback and other data before making decisions on this or future broadband promotions, however we can assure customers that we will continue to focus on giving them value,” says Steve Jackson.

Now unless my math is wrong the interesting figure here is the cable network, The network that suffered the most in terms of speed drop and did the most traffic.

If you take cable networks usage of 232TBytes and the time of the testing which was 54 hours in total you find that the Mbit/sec result is 10,011. Could Telstra have a bottleneck somewhere of a single 10gbit interface?




Most problems are the result of previous solutions...

Easy request :-)  Here they are for Snap only, we don't have enough probes from the others.  I have normalised the data to the maximum of the 1st, to avoid a debate about actual speeds as the speeds of each of our probes bear little relationship to the ISP performance, it is only relative speed that counts. 

 

Not much impact, suggesting that Snap was not affected.

Where was that measured to? Nat or Int? The SNAP issue sounds like Reach's Int went funny and was mucking up other wholesale clients which would only show in your test's for Int speeds - NAT shouldn't have been affected

we only do a webpage download on international and that's a lot more work to extract - sorry, maybe later

I've been pondering (be afraid!)

359 TB used in 54 hours, divided by 200k customers = 1.795 GB/customer over the 54 hour period. Extend that out to 730 hours in a typical month and you get an average usage of approximately 25 GB per customer per month.

TCL doesn't currently offer a 25 GB plan (at least not here in Whakatane; I haven't looked at cable prices) but looking at the other plans 25 GB could cost $100/month including phone etc.

Therefore... TCL could have a single plan at $100/month with unlimited GB. There must be something wrong with my calcs so please tell me what I've missed :)

Sorry not trying to take a dig at you, but it looks like Tru-Net put their name behind saying that the weekend AYCE trial was a success without examining the effect on international performance?

Of course national transit was not an issue, not of the above mentioned ISPs had any issues in that area, was all international so would be really good to get the full picture in the form of another lovely graph :)

Do you have any sanitized graphs you can share that show the impact to you?

Can't show effect the data however can show what Telstra did to my international ping times on my Snap connection...

Graphs yes, sanitized..no.   I've always been looking for a nice way to remove the lines from cricket/cacti graphs after the fact.

What would have been nice was a test between internal telstra connections... ie from cable to cable to eliminate the outbound gateway (possibly a 10GbE interface?).

Because from what I've read, parts of Wellington were hit hard with performance issues, kapiti not so much, some part of chch. Does this mean the internal infrastructure cannot cope with high load levels, rather than just the limited international bandwidth.

John, can the truenet routers be configured to test between one another as well? Might provide a little more information on each ISP ;)
