  @VoteLewko On my mates farm in the coast they have redundancy (Starlink) & anothet mate who runs ASIC’s infrastructure says they have always had both Telstra & Optus to try & avoid over reliance on a single network. So if farmers & some federal bureaucrats know this why don’t Victoria’s?🤡

  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

  @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

  AusAlert cost ~$130 million to rollout. A 13x increase from the $10m initial budget. Here are the known costs and estimates: $10m Initial Planning Taskforce $60-70m Carrier access tolls (Telstra, Optus, TPG) $30m Security architecture & hardening $20-25m Foreign hardware + offshore managed services $5-10m Public awareness, testing & administration Want to know how each allocation is spent? Too bad. Contractors and government use "Commercial-in-Confidence" clauses to keep specific commercial margins and costs hidden from the public eye. A 1300% blowout with no accountability.

  @Adrian_Arciuli @FIFAWorldCup Get rid of the mcg, Adelaide oval and Optus. Not designed for football. Terrible to watch a game

  @BinManIan Even if we were to propose the oval stadiums, the AFL is too greedy and has too much influence, they'll never allow the use of the MCG, Adelaide Oval and Optus Stadium for a month

  Origin Energy just had 900,000 customers' data breached, joining Optus, Medibank, Qantas and DP World. We treat each as a one-off. A pattern this long stops being bad luck and starts being the cost of collecting data you can't protect. #CyberSecurity #DataBreach

  @WestCoastEagles so Milan derby at Optus. In what part of the oval are they going to situate the rather tiny pitch? And are they erecting seating on a surface that's already having problems?

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

  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.
