Optus Outage Leaves Millions of Australians Without Mobile and Internet Services (abc.net.au) 59

Long-time Slashdot reader RobHart writes: During the night, the entire Optus mobile network went down and remains down. This is the second largest mobile network in Australia and it is the first time a network has gone down nationwide. It is affecting the trains in Melbourne and any business across Australia that uses the Optus service for phones or data. "Optus is aware of an issue that may be impacting some of our mobile and internet customers," the company wrote in a statement. "We are currently working to identify the cause and apologize for any inconvenience. In case of an emergency customers can still call triple zero."

Authorities are checking whether the outage is the result of a cyberattack, although they don't believe it is.

      dependency on always on internet creates lots of problems for a cashless society.

      FYI, cashless payments including apple/google/paywave do NOT require "always on". Phones need only occasional connection, and payment terminals will work without validation.
      It is up to the vendor whether to accept the risk of fraud. They may set a lower limit, or require ID for larger transactions.
      We got by for decades using credit cards without live validation.

    • It might come as a shock to many people, but credit cards can work offline! Heck, originally they were almost always used offline. Vendors simply used imprinting machines to create impressions of cards on carbon copy paper.

      My nearby bakery had an Internet outage a couple of months ago, after a large snowstorm. It didn't phase them at all, they simply wrote down the credit card numbers on pieces of paper that customers signed.

        Well not so secret secret is that in most countries the financial institutions allow for automatic approvals of cash transactions under a certain amount via the bank terminals in the stores when the network is unavailable.

        Example: In Australia at some stores an automatic $100 approval is granted for transactions under that limit. The actual transactions is cached and completed at a later time if the network is unavailable. Now this doesn't work in all shops. As each bank sets it's criteria on how a sho

          Does it work with chip cards or tap? I thought that they need at least one bank in the transaction to be online.
          • by upuv ( 1201447 )

            Yes,

            It is up to the bank that issues the terminal whether it will be supported for a merchant. The merchant can also so no. As the merchant is liable for any fraud of the system.

            Some banks around the world even have this built into their phone apps that take payments.

            This is exactly how pay terminals in planes work. They aren't on the network. Only very recently have planes got a reasonably reliable internet service. But those terminals only sync once they are back on the ground. ( For the most part. I

        I very much doubt that is an option in Australia. Any time I have been in any kind of retail outlet, if the card readers comms is out, it's cash or nothing. POS systems won't allow it either

        Well, they were semi-online. Small transactions would be done via the imprinting machine, but larger transactions would often require pre-approval.

        That didn't require you to leave the store - it just meant the cashier would have to make a phone call to their credit card processor to pre-a

      • It might come as a shock to many people, but credit cards can work offline! Heck, originally they were almost always used offline. Vendors simply used imprinting machines to create impressions of cards on carbon copy paper..

        We used those imprinting machines back in the early 90's but we authenticated every transaction by phone. I forgot to authenticate a $5K purchase once and almost lost my job.

        Incidentally, I chatted about this with a clerk at Harbor Freight a few weeks ago. She reached under the counter and pulled out her card imprinter. They still do it by hand when things go down, and they still call it in.

    • ... always-on internet ...

      A lack of electricity means shopping centres don't have lighting, air-con, lifts/escalators, PoS/EFTPoS terminals. When it was price-stickers and a department-code cash-register, a flash-light and a hand-held calculator allowed the shop to continue selling.

      When always-on fails, I can't start any games, they need today's adverts or a license-check to start. I can't do many tasks (eg. read the news/emails) because the data (and sometimes Software-as-a-service) is on a server/cloud.

      Does it? I mean Optus was down for most of the day? *looks left* *looks right*. It seems society endured. The world and society is far more resilient against such a "calamity" than you give it credit for.

      This isn't the first nation wide mobile outage (other providers have had it). This isn't the first payment processor outage (has happened many times). The only thing they all share in common is that we are all still here the day after, and the world didn't descend into a mad-max style dystopia.

      Singapore had it when a chiller failed and caused several datacenters to overheat causing payment systems to go down. Of course, they are practically a cashless society (and heavily monitored by government, at that).

      Of course, I suppose a little hubris applies because disasters rare

      You're talking localized events. Think bigger. All we need is a good solar storm, like the one we've found evidence for that happened about 14 thousand years ago or a little more, and any non-shielded electronics are buh-bye. Imagine the globe being wiped clean of modern electronics in a few seconds. It'd be mildly amusing for about two to three hours, but it would put an absolute halt to our current trajectory.

      Also if there is one thing learned from This (10 Million customers without internet and phones) less reliance on items that are network dependant is better. e.g. Office 365 and google docs were useless during the outage. I've had a number of clients now enquiring to get off the cloud or at least be able to function without it. Larger clients are looking to install backup internet and phones with other providers. Optus today, someone else soon
  • This lets people figure out how dependent they are on their smart phones and eftpos cards.

    I always tell people to keep enough cash on them for at least a day or two's expected expenses, a bit more if you want to plan for the unexpected.

    Usually the response is along the lines of "but eftpos will never go down".. then things like this happen and they can't buy lunch.

    • by hoofie ( 201045 )

      Australia really has become a cashless society - I have zero cash in my wallet right now and haven't had any in it for months. Needless to say I will correct that now.

      • by upuv ( 1201447 )

        How about making sure you actually carry a credit card as well. Moving all your cards to phone apps and then never carrying a card strikes me as very dumb.

        Oh my phone died and now you can't get home or eat. I've heard this way to many times from young people. The drama could be all avoided by simply carrying 1 card at all times.

    • The worst thing is that in Australia, the majority of big private and government enterprises now authenticate callers and website users with a 6-digit code by SMS. So when the mobile network goes down, nothing works at all. You cease to exist as far as most organisations are concerned. This is what happens in peacetime. Imagine if there was a war or something! The technology dependencies are now so extreme that the whole society could collapse in a day. Today was just a little preview. Much worse things wi
      • The Optus information leak was worse than it should have been, because the company kept more information on their customers than what was really needed.

        The Australian governments response was to try to shore up telco security, rather than ensure that more information than necessary for billing is not collected.

        The government wants telcos to collect as much data as possible on people for their own use when required. The metadata logging laws and the "assistance and access act 2018" mean they can be forced to

    • This lets people figure out how dependent they are on their smart phones and eftpos cards.

      People learned a big lesson today. They learned that they are still alive and okay at the end of the day and that an outage of smartphones and EFTPOS cards didn't actually mean the end of days despite their complete dependence and endless declarations of the end-of-days coming from folks like you on the internet.

      That is the only lesson anyone learnt. If you think that any single people will change as a result of this insanely rare minor inconvenience then you don't actually seem to understand people at all.

        Please cite where I said this would be a world apocalypse event.

        There was already someone elsewhere in this thread that said this reminded them that they should probably keep some cash on them just in case. So there's your one. It's not an earth shattering habit to keep cash on you so I'm not sure why you think it's such a hindrance.

        The world moves on, and no one cares as society moves ever more cashless.

        I'd disagree that no-one cares. They won't care until it affects them or they're put in a bad situation that they learn from, like teenagers only taking their phones to pay for

  • Working as a courier with no data or phone access was ... problematic. Going to populate that spare sim slot with another carriers sim, if I ain't moving, I ain't getting no moola.

  • We see a lot of that lately. Just imagine a major cloud goes offline (Azure came close just this year...). Instant chaos.

    Overall, we need more and smaller operators or things will go to hell.

    • Just imagine a major cloud goes offline (Azure came close just this year...). Instant chaos.

      Major clouds have gone offline. No not instant chaos. In fact it was much like the mobile outage today: minor inconvenience that people will ultimately soon forget.

      • by gweihir ( 88907 )

        As usual, you are bereft of insight and just make up nonsense. No major cloud provider has ever gone offline in a majority of serviced regions for any longer time.

  • All production changes go through change control. There are multiple approvers for change control. They are also responsible to implementation testing and change backout if something goes wrong. These approvers have personal responsibility when things go wrong. As the SLA's were busted - say downtime 10 hours plus, they should loose their bonuses and a pay cut. My bet is they have no-one technical, and it was probably pushed through from overseas, like Singapore. May as well 'save' money by having no loca
