  @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

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

  @MikeCarlton01 @Telstra That would be vodafone followed by optus and then telstra. Before anyone comes after me, vodafone went down for several months in 2010/2011, optus had a data breach in 2022 that affected nearly 10 million customers. Telstra just inconvenienced people.

  @Adrian_Arciuli @FIFAWorldCup MCG, Optus and Adelaide are Ovals and non starters. Cake Tin would and should be knocked down to expand. Given cricket isn't played there it would be rectangular, By 2042 Stadium Australia will have been rebuilt Perth should have a 40k rectangular Hopefully expanded Coopers

  @SkyNewsAust CEO return won't fix the problem - the Engineers are the important focus group whose expertise is critical to restore services [certainly earning their annual salary now -bonuses? "poof!" One imagines Optus satellite services in hot demand

  Ask Grok: Can ISPs block VOIP? 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. TCP/IP allows spam filters at the node level. This is one small example. TCP/IP remains neutral and ethical.

  @theheraldsun Telstra’s outage affected many states but Victoria’s train network was most affected. Why more than other states? State government stuff up. Optus has had outages too so you shouldn’t be fully reliant on these telcos.

  @ShimogaHuduga @ravikeerthi22 Optus stadium costs 8000cr. NaMo stadium is **** 👍🏻

  @JacintaAllanMP We saw similar issues with Optus. There is supposed to be redundancy that allows emergency calls to be carried over any available mobile network. If our emergency communications and critical infrastructure are meant to be resilient, why do single network outages continue to have such widespread impacts? It’s time to review whether our redundancy is truly independent, or whether we’re relying on backup systems that share the same points of failure.

  @Optus @itsallTag So I don’t get I got 5G on my phone when the test came through even though that there is currently an outouge on my closest network tower and I am only receiving 1 bar of 4G because of the outage of that area tower so it doesn’t make sense to me towers also need to be fixed irl
