  @EVERALDATLARGE Agree Everald. Yes there was a system fault, and yes 000 Failed. And Yes after the Optus problems the Labor Minister for Communication put in place to hopefully fix the problem. Calling for government to leave is a bridge too far. It will take time to fix. It’s not down every day

  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.

  @BigDog_USA @Telstra You must be deaf and blind. It was a massive outrage when Optus went down too. Not everything is about an agenda **** head.

  @heidimur This isn’t just about Telstra. We saw similar issues with Optus. 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 backups that share the same points of failure.

  @nadarnation @rossivision Optus stadium is far superior to Subi. Subi was hideous to get in and out of (both the oval itself and the suburb) , terrible design and horrid to watch football at. Camfield is right next door, Crown a short walk away and great facilities inside the stadium.

  @Optus Hi Jay, I dont think you can assist me, one of your optus colleagues has told me by phone, nbn is having an unplanned outage, nbn isnt saying how long it will last

  @CharlesSzulc Telstra will appear before a Senate inquiry into its outage, starting next Friday. Senator Henderson is involved in the (apparently ongoing) Optus one. It'll be be interesting if she now asks questions of Telstra, as will be forthcoming media reports.

  @simonbiddle @taipan168 As much as I defend funding government services, the notion that government run IT will be more reliable than Telstra/Optus is just not believable given the various IT issues we see on a constant basis from Centrelink and who can forget the debacle of the last Census

  @GraemeEtt If it's being sent via Telstra or Optus god help us.

  @james00000001 Interesting to see if they were Optus phones that didn’t receive the message - wouldn’t be surprised Optus is so ****
