UPDATE: TelstraClear’s unmetered broadband weekend can be counted a success after customers took advantage in a frenzy of up and downloading, the company saidthis afternoon.
Customers used two and a half times more data overall than the previous weekend, TelstraClear said. Total usage was 359 terabytes (TB), 216TB more than the weekend before.
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, TelstraClear said.
The company also seized on TrueNet's independent testing (below) and TrueNet's analysis that, overall, the trial was a success.
“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’,” TelstraClear head of consumer markets Steve Jackson said.
TrueNet found DSL speed dropped by up to 40%, and Cable by up to 64%. At times, congestion prevented testing.
“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," Mr Jackson said.
“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,” Mr Jackson said.
7am: TelstraClear's all-you-can-eat weekend saw many complain about a degradation in speed, and here-and-there spot tests by individuals.
A number of customers told NBR their connections were unusable at times.
This morning independent testing company TrueNet has released figures that offer some empirical evidence. TrueNet uses a nationwide network of volunteers who install probes on their connections to track ISP performance in a survey carried out in partnership with the Telecommunications Users Association (Tuanz).
TrueNet principal John Butt said over the no-limit weekend, "TelstraClear national speeds reduced by almost 40% for ADSL customers and 64% for Cable customers." (Yesterday, TelstraClear said only international traffic slowed.)

Given the circumstances, "the company managed the weekend well .... Overall customers remained able to surf the net and to access most services,” Mr Butt said.
Mr Butt said TelstraClear Cable customers were most affected. Their speed dropped to being on par with DSL.
“This is what we would expect. The speed has reduced to the available capacity, with both technologies having equal access to capacity and thus having equal speeds.”
Customers using TelstraClear’s unbundled DSL service (that is, accounts fed from Telecom exchanges where TelstraClear has moved in its own DSL switching gear) could well have escaped unscathed, with TrueNet’s testing showing minimal impact for unbundled customers.

Download times for internationally hosted webpages were affected, but overall the service continued to operate.
Test results of international webpage download times show that TelstraClear struggled with capacity until Sunday morning at 6am when they obviously fixed a problem, Mr Butt said. This fix started to fade again by the peak of 8pm and 10pm.
Mr Butt said TelstraClear clearly had overloading issues on the Saturday, but by Sunday had largely resolved the problem.
“From 6am to 6pm, the service was operating as it normally does, but once the volume built up again after 6pm, the performance degraded.”
All in all, TelstraClear performed quite well considering the volumes of traffic being sent and received, Mr Butt said.
TrueNet found the average speed over the weekend was 7Mbit/s, but for some customers the speed available was potentially worse, Mr Butt said.
The average speed during the peak hour of 10pm on Friday night was 3.3Mbit/s, with the peaks on Saturday and Sunday a little earlier and with more capacity with the average speed being 4.1Mbit/s and 3.9Mbit/s respectively.
Too congested to measure at times
An interesting statistic is the number of times our probes were unable to measure - potentially due to congestion, Mr Butt said.
There were no missed measures for ADSL probes throughout the weekend, but for Cable, missed tests ranged from 7% (Saturday) to 18% (Sunday).
In the previous month, tests on Cable probes missed measuring less than 2% of the time, although on one day, the 23rd November, missed measures reached 7%, ie the same as Saturday.
Missed tests occur when volunteers' use of the Internet coincides with the TrueNet probes attempts to complete their own seperate, and independent download tests. Other missed tests would be due to time-outs if congestion impacts tests, Mr Butt said.
"TrueNet's interpretation is that TelstraClear's experiment with unlimited broadband was a success with average speeds ranging from 3.3Mbit/s to 7Mbit/s with a limited number of outages."
