  Optus 4G has been rubbish all afternoon. Not completely broken, just bad. I presume it’s DNS somehow.

  @Optus gahhh since the switch over with ‘Vivid Wireless’ my Internet has been painfully slow the last two days ... been trying to watch Netflix for 2 hours now and only managed to get 10 seconds out of an episode 😫 I don’t work split shifts 365 days a year not to enjoy my break

  @Kate3015 Remember 18 Sept 2025 when Optus had a 000 outage because no one though to make some test calls to ensure the service was working after an upgrade? Doing a test is basic common sense.

  @BritishHodl Grok can an ISP block voice over IP? Yes, ISPs can block Voice over IP (VoIP) traffic at their network level, and many do so in practice. This is technically feasible using tools like port blocking, deep packet inspection (DPI), and other traffic management techniques. How ISPs Block VoIP ISPs control the core network infrastructure, so they can inspect and filter traffic before it reaches customers. Common methods include: Port-based blocking**: Traditional VoIP often uses specific ports like UDP 5060/5061 for SIP (signaling) and a range of ports (e.g., 10000–20000) for RTP (media/voice). ISPs can simply drop traffic on these ports. Deep Packet Inspection (DPI)**: This examines not just headers but packet contents, signatures, packet sizes, timing, and protocol behavior to identify VoIP even if it uses non-standard ports or obfuscation. DPI can dynamically detect and block SIP, RTP, or app-specific patterns (e.g., Skype, WhatsApp calls). IP address or domain blacklisting**: Blocking known servers of VoIP providers. Protocol anomaly detection or traffic shaping**: Dropping or throttling UDP-heavy, low-latency streams typical of voice calls. Real-World Examples Certain countries and carriers (e.g., in the Middle East, Morocco, Philippines, or places with state telecom monopolies) block VoIP to protect traditional phone revenue or for regulatory reasons. Mobile providers like Optus 4G or others have blocked SIP traffic. Corporate/school networks or bandwidth-limited ISPs sometimes block or deprioritize VoIP to conserve resources. China has historically blocked VoIP, though workarounds emerged over time. Limitations and Challenges for Complete Blocking Encryption and obfuscation**: Modern VoIP (e.g., over WebRTC, HTTPS, or apps like Signal/WhatsApp) is harder to detect reliably. DPI isn't foolproof against randomized ports, variable packet patterns, or VPN-like wrapping. VPNs and tunnels**: Users can often bypass blocks by routing traffic through a VPN, which encrypts and hides the VoIP signature. Evasion techniques**: Providers and users adapt with port hopping, STUN/TURN servers, or proxies. False positives**: Overly aggressive blocking can disrupt other UDP-based services (gaming, video streaming). Complete, unbreakable blocking is difficult long-term without also harming general internet performance, but partial or effective blocking for most users is very achievable. Why ISPs Do This Reasons include protecting legacy telephony revenue, complying with regulations, managing bandwidth, reducing congestion, or enforcing content policies. In summary, yes—ISPs have both the capability and precedent for blocking VoIP, primarily via DPI and port controls, though motivated users can often circumvent it. If you're dealing with a specific ISP or scenario, details could help narrow down options.

  @borisstephens Firstly, taxes do not fund government spending, critical misconception the establishment perpetuates on purpose to justify austerity. Secondly, you're right to say that just throwing money at problems does not automatically fix anything. You still need competent management and a plan. All nationalisation does at a baseline is remove the profit motive that leads to cutting corners on network maintenance to save money, which is what leads in part to outages like this. And I haven't just proposed renationalisation, I've also proposed using Optus' satellite expertise to create a publicly-owned, privacy-first satellite internet network to challenge Starlink.

  @JHewy23 @wigley_matthew @FootyonNine By “this crap” do you mean obvious fact?? So Optus stadium is Freo’s home ground. If they had 4 other sides that use it as their home ground too, but Freo had twice the supporter base of those clubs so can dominate the crowd noise each week and barely leave WA you wouldn’t see that as an enormous advantage over the competition??? Of course it is. That doesn’t mean you’re wrong at all, they have to play the other teams that occupy the MCG as home also. It’s also not any fault of Collingwood to have the biggest supporter base in the land either. Both points can be correct at the same time. But there’s no doubt it’s an enormous advantage every year for Collingwood, Richmond, Melbourne and Hawthorn….

  @Democracy_Duck @ABCmediawatch Are you suggesting giving the network back to public ownership? To an organisation like NBN where rejects from Telstra & Optus go to work? (Including Telstra's so-called risk management 'experts' BTW) With ACMA keeping an eye on things?

  @amagickeagle999 You stupid ****. She was mouthing off about increasing standards and enacting penalties for service outages after the Optus crash but has done **** all. So you partisan ******** get some facts, she ****** up.

  Let’s forget the umpiring, taunting and constant booing of this underrated crowd, what’s the go with this Optus stadium deck, the worst ground in the AFL currently, on par with what was dished up for origin last night. Awful. #aflfreoswans

  Halftime at Optus. That second quarter was, despite the inaccurate set shots, actually a lot better than the first. But we're still down by 7 points, so it's time for the Lions to regroup and go again in the third term. Hopefully the Eagles will finally lose their legs by then. #AFLEaglesLions

  Why in a capital city do all fail with internet coverage In out back Truganina phones and internet mobile connection are a massive fail. @Telstra @Optus @amaysimAU

  @GenVavancee Given the time the outage happened it probably was some form of maintenance and a routing error happened. They happen all the time but much like Optus this was a big one.
