  @KobieThatcher @Ann19851873 Agree 💯 Also with the recent Telstra outage and formed Optus outage. Both affecting Eftpos networks and ATM’s. Cash is king for many reasons including privacy. Do not let cash die out.

  @karavas_alex @BrianJArbuckle 50k of intense support at Optus which configuration isn't too dissimilar to MCG. Freo kicked 100+ in the 2 games at the G. Doesn't phase them mentally. Sat was a rare shootout. A GF doesn't have that level of intense support - 100k v 50k doesn't make a diff.

  @KatyKray73 In the event of a global war, data centres will be prioriy targets for bombs, missiles, and emp nukes, because.... These data centres will control everything. Ffs, telstra and optus outages caused enough disruption, imagine a total testra and optus blackout, multiply that by 100

  We need the telco to learn #auspol but as an Optus customer .who has seen it before, what happens hear? Zero cash for us, but the Optus bill goes up to cover this pay out to lawyers and a few who could afford them. Same as the mob who are suing Coles. Pays lawyers and a few and we all pay the price in the new prices, not Optus or Coles

  @AJG_87 @MiguelS92940618 This is where I’m at. Looking at yesterday alone we had the personnel on park to beat Richmond. Can blame poor kicking but it was the same against Port & North at Optus. We have gone backwards post bye If we have the personnel then for me it’s the coaching staff that are failing

  @BritishHodl Grok can an ISP block voice over IP? 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.

  Train line to Optus stadium is down. Good luck, Freo fans....

  @satoshigoy @Optus AusAlert isn’t delivered through @Optus. On LTE, the cell sends a Paging indication 'cmas-Indication-r9' then the warning itself is broadcast in SIB12. A working SIM or successful network registration is not required.

  @iisancs @Optus every two months? mine stops every Two hours, WTF @Optus im tired of this ****, one week will be ok, then next, every two hours it just stops working for for 10 minutes then start again, and its the neighbours having the same issue it s not just me, Dort ya **** out.

  It's not possible for that to happen. I think not quite as bad as at Optus, both require a full clearing of the decks across the whole club. This isn't a rebuild in culture which is clearly what's required. It's just collecting players & not making them gel
