NBN's good-to-go dates remain confidential

Patch-cables spark teacup-storm


Bill Morrow, CEO of nbnTM, the organisation building Australia's national broadband network (NBN) has sparked a political storm over patch cables.

Speaking to a Senate Estimates hearing yesterday, Morrow also said the company's “ready for service” documents – which tells staff and retailers when individual premises can be activated on the National Broadband Network – should be kept confidential.

In response to a request by opposition communications spokesman Senator Stephen Conroy to table a copy of the document he had, Morrow said it would cause confusion among customers and damage the nbnTM brand.

He explained that ready for service dates change in the six-to-twelve months between a build starting and being accepted by nbnTM.

Giving consumers a date and then changing it is “irresponsible”, Morrow told the hearing, and might mean they delay taking up an NBN connection or even “take up alternative services” (which seems an odd thing to say since in most of the country the NBN is meant to be the only game in town).

The discussion of patch cords, however, is what's lit up the wires.

The cables in question are being used to connect the existing Telstra pillars – street-level distribution points – to the nodes in the fibre-to-the-node (FTTN) portion of the network.

nbnTM is taking a fairly unremarkable approach to the installation process.

Instead of disrupting hundreds of customers at a time to disconnect the existing pillar, install the node, and reconnect the customer tails, the company is leaving the services in place while it gets the node ready, then hooking the node up with jumper cables.

With thousands of nodes and a few million customers, that's going to need an awful lot of jumper cables. Morrow told the hearing nbnTM has so far spent AU$14 million on 1,800 km of cable, both relatively small amounts in the context of the rollout.

Morrow explained to estimates that each node-to-pillar installation used about 350 metres of patch cables, meaning nbnTM has enough patch cords for around 5,000 nodes in the rollout.

Eventually, FTTN is intended to serve 4.5 million homes. If there are around 200 homes per node, the company will be looking for another $60 million worth of patch cables to complete the rollout by the 2020 target date.

It's no surprise, then, that Morrow told estimates cable supplier Prysmian is ramping up its production. nbnTM's current supply is good for about five months' rollout work.

Morrow also told the hearing that if node-to-home copper was found to be in poor condition, it would be replaced, and only if the cost of fibre was lower than copper for a connection would fibre be used. ®

    Screencastify, a popular Chrome extension for capturing and sharing videos from websites, was recently found to be vulnerable to a cross-site scripting (XSS) flaw that allowed arbitrary websites to dupe people into unknowingly activating their webcams.

    A miscreant taking advantage of this flaw could then download the resulting video from the victim's Google Drive account.

    Software developer Wladimir Palant, co-founder of ad amelioration biz Eyeo, published a blog post about his findings on Monday. He said he reported the XSS bug in February, and Screencastify's developers fixed it within a day.

  • FTC urged to protect data privacy of women visiting abortion clinics
    As Supreme Court set to overturn Roe v Wade, safeguards on location info now more vital than ever

    Democrat senators have urged America's Federal Trade Commission to do something to protect the privacy of women after it emerged details of visits to abortion clinics were being sold by data brokers.

    Women's healthcare is an especially thorny issue right now after the Supreme Court voted in a leaked draft majority opinion to overturn Roe v Wade, a landmark ruling that declared women's rights to have an abortion are protected by the Fourteenth Amendment of the US Constitution.

    If the nation's top judges indeed vote to strike down that 1973 decision, individual states, at least, can set their own laws governing women's reproductive rights. Thirteen states already have so-called "trigger laws" in place prohibiting abortions – mostly with exceptions in certain conditions, such as if the pregnancy or childbirth endangers the mother's life – that will go into effect if Roe v Wade is torn up. People living in those states would, in theory, have to travel to another state where abortion is legal to carry out the procedure lawfully, although laws are also planned to ban that.

  • Zuckerberg sued for alleged role in Cambridge Analytica data-slurp scandal
    I can prove CEO was 'personally involved in Facebook’s failure to protect privacy', DC AG insists

    Cambridge Analytica is back to haunt Mark Zuckerberg: Washington DC's Attorney General filed a lawsuit today directly accusing the Meta CEO of personal involvement in the abuses that led to the data-slurping scandal. 

    DC AG Karl Racine filed [PDF] the civil suit on Monday morning, saying his office's investigations found ample evidence Zuck could be held responsible for that 2018 cluster-fsck. For those who've put it out of mind, UK-based Cambridge Analytica harvested tens of millions of people's info via a third-party Facebook app, revealing a – at best – somewhat slipshod handling of netizens' privacy by the US tech giant.

    That year, Racine sued Facebook, claiming the social network was well aware of the analytics firm's antics yet failed to do anything meaningful until the data harvesting was covered by mainstream media. Facebook repeatedly stymied document production attempts, Racine claimed, and the paperwork it eventually handed over painted a trail he said led directly to Zuck.

  • Florida's content-moderation law kept on ice, likely unconstitutional, court says
    So cool you're into free speech because that includes taking down misinformation

    While the US Supreme Court considers an emergency petition to reinstate a preliminary injunction against Texas' social media law HB 20, the US Eleventh Circuit Court of Appeals on Monday partially upheld a similar injunction against Florida's social media law, SB 7072.

    Both Florida and Texas last year passed laws that impose content moderation restrictions, editorial disclosure obligations, and user-data access requirements on large online social networks. The Republican governors of both states justified the laws by claiming that social media sites have been trying to censor conservative voices, an allegation that has not been supported by evidence.

    Multiple studies addressing this issue say right-wing folk aren't being censored. They have found that social media sites try to take down or block misinformation, which researchers say is more common from right-leaning sources.

  • US-APAC trade deal leaves out Taiwan, military defense not ruled out
    All fun and games until the chip factories are in the crosshairs

    US President Joe Biden has heralded an Indo-Pacific trade deal signed by several nations that do not include Taiwan. At the same time, Biden warned China that America would help defend Taiwan from attack; it is home to a critical slice of the global chip industry, after all. 

    The agreement, known as the Indo-Pacific Economic Framework (IPEF), is still in its infancy, with today's announcement enabling the United States and the other 12 participating countries to begin negotiating "rules of the road that ensure [US businesses] can compete in the Indo-Pacific," the White House said. 

    Along with America, other IPEF signatories are Australia, Brunei, India, Indonesia, Japan, South Korea, Malaysia, New Zealand, the Philippines, Singapore, Thailand and Vietnam. Combined, the White House said, the 13 countries participating in the IPEF make up 40 percent of the global economy.
