  @Gizmologist_ Funny how telco’s never had this problem before wouldn’t surprise me if Telstra orchestrated Optus outage to knock them out of the market like Qantas did to Rex blocking airports We’ve had polair lately at night doing thermal mapping of the area fly round almost 2hrs each time

  @HappyNacho73 I've got two numbers and the Telstra one on e-sim was very loud compared to the Optus network one.

  Millions of Australians may have had data accessed by “hackers” after Origin Energy confirmed it is investigating a cybersecurity incident. It could be one of the biggest “cyberattacks” Australia has faced following similar strikes on Optus, Medibank and Qantas. Most of the cyber “hacks” on Australian companies have actually been leaks due to incompetent, lazy IT staff—Origin received and email from the “hacker” but because said hacker didn’t reply to questions from Origin, the company pretended it didn’t happen until the hacker contacted the median. As I said, incompetent lazy IT staff.

  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.

  @Optus Thanks, but that doesn’t address what actually happened. I was in the emergency broadcast area with a compatible device. There was no Optus coverage, but there was coverage from another network. Despite that, I never received the AusAlert. If emergency alerts can’t be delivered when your carrier is unavailable, even though another network is in range, that’s a significant issue. In an emergency, people shouldn’t miss life-saving warnings because of which carrier they’re with. Can you clarify whether AusAlerts are expected to be delivered in this scenario, or is this a limitation of the current system?

  @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

  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

  Telstra network issues rumble on in qld. Messages delayed Calls dropped. How's Optus & Vodaphone doing?
