  @Bigly20 @Caitlen2310 The Guardian asks why hasn't the government acted on regulations since the Optus outage last year? I ask what did the Coalition do about regulations after the Telstra outages in 2016 & 2018? What private discussions and/or guarantees did they obtain from Telstra after those events? In 2018 Triple Zero calls dropped out across 5 states for 10 hours. If it were so simple why didn't the Coalition insist on Telstra installing back up systems? Maybe we need a Royal Commission (joke).

  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.

  @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

  @externallylaws Can confirm the outage impacted the wilds of NT - where there is no Optus service.

  @Optus are the worst telco on the planet. You’d think that after over 30 years of loyalty they’d be willing to negotiate a compromise and maybe even a little leniency to someone in financial hardship, but no. They don’t care. It’s all about the money. Stay away from @Optus

  @PGJohnson77 @Adrian_Arciuli @FIFAWorldCup Adelaide Oval and Optus are fine because AO is narrow and Optus has raised seats. Agree that the MCG is a very poor viewing experience.
