  • superman2144 2144Superman (@superman2144) reported from Sydney, State of New South Wales

    @Optus @networkoutage why is my nbn not working at Cumberland Rd, Auburn 2144 ...

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

    @joshh_dp Yup. Has been perfect for years. Suddenly it’s bad only in the peak but I have to wait for an NBN technician to look at the NTD 🙄

  • aussiepomm aussiepomm (@aussiepomm) reported from Galston, State of New South Wales

    So - @NBN_Australia cut off home phone when attempting to install but can’t complete job, and now @Optus have cancelled my ADSL account. Neither are particularly helping (blaming each other) so I guess it’s the Telecommunications Industry Ombudsman to assist! Been a horrid 24hrs

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

    @AUSFestivus @Telstra I had to take my mobile to Vodafone a few weeks ago because of Telstra congestion issues in the CBD. I’m trying to give them a chance here because the NBN with them has been great with no peak congestion for 3 years until last week. But Vodafone NBN is looking good right now.

  • IainBrewSydney Iain Brew (@IainBrewSydney) reported from Sydney, State of New South Wales

    @fictillius The way around it is to put a small switch between the NBN Modem and the ISP router. Use their router purely for voice and a second router of your choice for data. It seems 2x devices can sign in with same credentials so will be testing that out.

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

    @Telstra Last night I could barley load my online uni course when speeds got down to 4Mbps. In fact it will probably be faster if i disconnect the NBN and use the 4G backup of an evening.

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

    @Radxiation nbn is down playing on 4 g haha

  • Giulzjrc Julia Cohen (@Giulzjrc) reported from Sydney, State of New South Wales

    @Telstra my house does not yet have nbn. Until this week good cable. You’ve been doing work in @hornsby to prep for nbn. Now every night no service post 8pm. Other times constant dropouts. #nbn #nbnisajoke #telstra #hornsby #idontwantnbn @wendy_harmer @

  • paloappie Chelsea Feltham (@paloappie) reported from Sydney, State of New South Wales

    After two weeks of no internet with @Optus due to “back end issues” with my relocation, I was told it could be a further 21 days to get connected. I cancelled my service. 30 mins after submitting the form on the @Aussie_BB website, my NBN was connected. Customer service folks!

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

    @0dayssincemeltd In contract so just waiting for them to acknowledge it’s broken so I can leave with no fee. Complaint in with Telstra and now the TIO. All Telstra are doing is sending an NBN tech to look at my NTD

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

    iiNet support wasn’t interested in the fact they had iiNet NBN 50 and suddenly they had Vodafone NBN 100 running at their house. Just say it’s impossible.

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

    @CameronWatt They had a data feed issue last night. My POI is good for Aussie BB but I might give Vodafone NBN a go. Get a bundle discount and $69/m for 100/40 for first 6 months. Plus the 4G backup

  • Ronki Ron Curry (@Ronki) reported from Sydney, State of New South Wales

    @Telstra Automated answer and on hold. Just called back on another phone and answered straight away. Go figure (but problem not fixed). I had such a great internet experience before being moved to NBN!

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

    ADSL service cancellation has been requested. I'm now all-in on the #nbn

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

    @Telstra No reference numbers but I have now made a complaint. There’s clearly something wrong with your network but tech support just want to blame my network or the NBN and want to waste time getting and NBN tech to look at a Fibre NTD that works fine except for peak hour.

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

    Another day another NBN outage... and right as I got home. Pleeeease don’t let this turn into an ongoing saga like it was with Optus HFC 🙃

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

    @Telstra The first tech support person last week said the congestion would be fixed within 24hours. 4 days later the internet is barely useable during peak times. There’s clearly inadequate CVC or an issue on your network and waiting for an NBN tech before doing anything is waste of time

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

    Also before they moved out their home internet had suddenly moved to Vodafone NBN but their iiNet account still showed usage up until the people at the new house turned off the modem. Sounds like a churn was done but iiNet support claims that is impossible

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

    @Telstra It’s FTTP. The Gen 2 modem has been rebooted. The tests have been run. All that’s happened is an NBN tech has been booked who is going to look at the NTD and say it’s fine. Fibre doesn’t develop an issue for certain hours of the day.

  • meggsie79 MEGAN SAMUEL (@meggsie79) reported from Sydney, State of New South Wales

    @CynicalAU @Optus @TPG_Telecom Don’t do it @TPG_Telecom are terrible. At present we haven’t had email access for almost 3 days and they seem in no rush to rectify the issue. Also my NBN installation was an experience I’d prefer to forget. 15 missed appointments and sub-standard speeds

  • pat_devlin Pat Devlin (@pat_devlin) reported

    We're working from home. We're homeschooling. We the network more than ever! It's insanely aggravating when our NBN bounces every 30mins. Dear #NBN_Australia PLEASE I'd much rather have reliable connectivity then super-fast internet speed!! (don't correct me, I know what I typed)

  • ivaforgotton ive forgotton (@ivaforgotton) reported

    Optus NBN down from midday 9 sept to 07:00 10 sept Every Week This is Becoming a Habit 19 fuken Hours thats Bull **** and the ***** Play dumb.

  • vbastos_aus Vincent Bastos (@vbastos_aus) reported

    Why does @telstra report that NBN has a planned outage in my area but @NBN_Australia does not?

  • haamfish Hamish (@haamfish) reported

    @JordanZac @NBN_Australia Does it go out when it rains too? That’s the problem with copper. So many faults! I worked on faults in the UK. Networks are 100 years old now and they weren’t designed to carry data.

  • busta1955 Lost Forward (@busta1955) reported

    So let me get this right, @Telstra. By your own admission, my NBN service does not meet even minimal throughput standards, but you are now going to charge me $5/month extra on my bill. Is this some kind of strategy to drive me to Optus 5G? If it is, it’s working.

  • dutchnstormy Stormy (@dutchnstormy) reported

    @nqwatcher @Telstra I can recommend Internode. I’ve been a customer for 10 years, both ADSL and now NBN. Had very little cause to contact them or complain - reliable, good service, domestic call centre, and reasonable pricing.

  • Melissainau Melissa 🎲🎲🎲 (@Melissainau) reported

    F: so can you help me set it up now, because we have no internet. ISP: no, that is what the Senior Support Technician will call you to do. [note that accessing our NBN box requires lying on the floor which I can’t do at the moment] 2/..

  • GeorgeShtayh George Shtayh (@GeorgeShtayh) reported

    @Optus do we have an issue with NBN in the Blacktown area?

  • rubyfreyja rubyfreyja (@rubyfreyja) reported

    Never had so many issues with a home phone for a 90 year old since nbn installed. They are dependant on this service, Priority Assist but they wouldn't be able to work the technology if someone didn't come over to help them. Useless for an emergency. @NBN_Australia @Telstra

  • haamfish Hamish (@haamfish) reported

    @JordanZac @NBN_Australia holy ****, what happened? or is it too soon to know?
