  • gb_satishkumar Satish Kumar (@gb_satishkumar) reported from Sydney, State of New South Wales

    @Telstra @NBN_Australia I can’t wait anymore to have my NBN DROPOUT compliance fixed that is on going from October 22nd. There were multiple calls with your customer service but no progress yet. Compliance reference 1-2258 557 835 814

  • manaz_d Robert Hudson (@manaz_d) reported from Sydney, State of New South Wales

    @Idealaw @NickRossTech @kcarruthers @TurnbullMalcolm @NBN_Australia @matt_barrie @Aussie_BB Reminds me, I need to cancel my Telstra Bigpond account now I am on @Aussie_BB NBN...

  • fridley James Fridley (@fridley) reported from Sydney, State of New South Wales

    So now if I want to connect the $380 device we were sold to fix the poorly working backup connection while we wait for the poorly ordered NBN location move to be completely cancelled before it can be re-ordered correctly, I need to buy another sim card for $80/mth to make it work

  • thepatrick Patrick Quinn-Graham 🏳️‍🌈 (@thepatrick) reported from Sydney, State of New South Wales

    Oh goody, half an hour in to an NBN outage. Technology hates me lately.

  • camozspurs Cameron Whyte (@camozspurs) reported from Sydney, State of New South Wales

    @Kezzacarpenter @Optus Yes but it’s working ok now they have there own NBN support team and you get a case manager so not as bad as I thought

  • jasonbak Jason Baker (@jasonbak) reported from Sydney, State of New South Wales

    I really can't wait until I have 5G coverage so a can shove the NBN where it belongs. Sick of dealing with ISP technical support.

  • Jock500 Keith Stewart (@Jock500) reported from Sydney, State of New South Wales

    @telstra your outage page showing an outage of the NBN in postcode 2087. Cant get any info on how long it’s expected to be down. Have tried all your websites etc. do you have any idea

  • deepchild 𝔇𝔢𝔢𝔭𝔠𝔥𝔦𝔩𝔡 / 𝔄𝔠𝔥𝔞𝔯𝔫𝔢́ 🌱 (@deepchild) reported from Sydney, State of New South Wales

    @frogworth Life hack - spend your day in any icy cold Sydney bus on constant loop, tethering 4G on your laptop because the NBN sucks anyway. Cheaper than a co working space.

  • manaz_d Robert Hudson (@manaz_d) reported from Sydney, State of New South Wales

    @Originaltibbedy @marckean @NickRossTech @TurnbullMalcolm @NBN_Australia @matt_barrie @Aussie_BB It is my understanding that backward compatibility is limited to a version or two. One of the big delays in Telstra going to DOCSIS3 was apparently because they had old kit (theirs and customers) still on the network.

  • NudgerSS 'Nudger' Needham (@NudgerSS) reported from Sydney, State of New South Wales

    Australian broadband has to be amongst the worst in the world. Constantly keeps dropping out. NBN sort yourselves out.

  • TracyMcNamara6 Tracy McNamara (@TracyMcNamara6) reported from Sydney, State of New South Wales

    Guess I’m lucky I’ve just lost NBN and Foxtel, still have power Very scary storm, some big branches down but luckily no trees

  • oceanswims oceanswims (@oceanswims) reported from Sydney, State of New South Wales

    Hey @Telstra, how does this work... I cancel a broadband cable that I’ve had with you for years to avoid being forced onto NBN, and instead I commit to you for 3 years with home hub. And you want to charge me cancellation fees. Please explain the sense in that.

  • DeborahKent10 Deborah Kent (@DeborahKent10) reported from Sydney, State of New South Wales

    @NBN_Australia @Telstra Gr8 work shut down my WiFi with scare mess on my screen 2 force me 2 switch to NBN #shockingtactics no internet 😡

  • hitinman Just Davo (@hitinman) reported from Sydney, State of New South Wales

    **** the #nbn been crap all afternoon on again off again. Losing stuff I upload to God knows where. WTF 65th in the world and falling. And if #nbn tell me to contact my provider I will scream. ITS NOT MY PROVIDERS FAULT.

  • AUSFestivus It's dogs all the way down (@AUSFestivus) reported from Sydney, State of New South Wales

    @GordyPls The concept of over provisioning a service to account for header and encaps overhead isn’t new and has been a standard WAN product factor since before NBN was born. NBN chose to do this solely because they don’t exist to satisfy consumer sentiment. 🙄

  • fictillius Quiet, Evan (@fictillius) reported from Sydney, State of New South Wales

    @NewtonMark @NBN_Australia Heh. Big T are proposing to use NBN FTTB to deliver an enterprise service to our office in the CBD. I think I’ll decline and use a provider that brings their own pipe in.

  • DeborahKent10 Deborah Kent (@DeborahKent10) reported from Sydney, State of New South Wales

    @JBSFinancialJB @NBN_Australia @Telstra sure was looked like I had a mailware problem 🙄

  • bigmig81 ⚫️⚪️🔵Michael ⚫️⚪️🔵 (@bigmig81) reported from Sydney, State of New South Wales

    Nice work @Telstra ... issues with internet, " system glitch" inability to have an NBN connection processed and no real time frame for having it rectified...at least you offered the disconnection team 😂

  • mikeaubrey2 🇦🇺mikeaubrey🏳️‍🌈 (@mikeaubrey2) reported from Sydney, State of New South Wales

    @lynlinking Blame LNP Government for this, they have stuffed up the NBN & won't be told, won't discuss, won't write down the $51+bn & therefore taxpayers pay twice, once for build & second for overpriced connection deals through RSP's.......LNP were warned......watch how much this costs us

  • psg_au Peter (@psg_au) reported

    @NBN_Australia The NBN tech has identified & agreed it is YOUR phone line that is the issue -FIX IT

  • higgzee Tim (@higgzee) reported

    @Telstra is there anyway of having a conversation with someone in real time? Using your chat service for my last query took 24 hours and now my NBN order is lost

  • Aussie_BB Aussie Broadband (@Aussie_BB) reported

    @filmgirl152 Hi there, sorry to hear it is not running well, from the email hopefully NBN has already seen the issues and are looking to get the area stabilized! If you do need to call we are open 8am to Midnight AEDT. - Adam

  • psg_au Peter (@psg_au) reported

    @ButIJustGotHere @NBN_Australia You are lucky. At least yours works to be able to go down... mine is a paperweight that has never worked

  • maths_kath Dr Katherine Seaton (@maths_kath) reported

    @nomad_penguin With the installation of the nbn last week, people calling us has not been a problem. Nevertheless we should probably get it fixed.

  • officialdimsim sdimsim (@officialdimsim) reported

    Oi @ScottMorrisonMP why ******** am I lagging on COD? Could it be because the NBN is ****?

  • EconoGarry EconoGaraidh (@EconoGarry) reported

    @chrismurphys @Telstra I use Optus mobile broadband. A year with no problems. Faster download than nbn. Slower upload but who cares. Their webmail is not to be recommended though.

  • madbeau Beau Britton (@madbeau) reported

    @NBN_Australia 10 hours. still down.

  • jurdman jurdman 🎮 (@jurdman) reported

    @Pez_Bro Love when your streaming content requires, actually working nbn and yet Australia cannot get their **** together to have fast, reliable internet. We are honestly a worldwide laughing stock when it comes to internet speeds. It'll cost me 3k if i want to upgrade from fttc to fttp
