  @OMGTheMess She was supposed to implement a new BCP after the Optus outage. What are we paying her to do? Other than drink champagne on her business class flights? What has she actually achieved? Does anyone know?

  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

  @theheraldsun Telstra’s outage affected many states but Victoria’s train network was most affected. Why more than other states? State government stuff up. Optus has had outages too so you shouldn’t be fully reliant on these telcos.

  @bamberee 🤷 Not unexpected. Optus version worse. BUT the same as then, today. Lynch - no plan. Rebound - no defence. Outlet for hand pass - nil. Even with Marcus to buy half an hour. Selection/positions - bewildering. Reid DE&t/o really poor-noone with him? No coaching response to these

  @james00000001 @Schtang Optus is not the problem! It's individual users and their settings.

  @JHewy23 @wigley_matthew @FootyonNine By “this crap” do you mean obvious fact?? So Optus stadium is Freo’s home ground. If they had 4 other sides that use it as their home ground too, but Freo had twice the supporter base of those clubs so can dominate the crowd noise each week and barely leave WA you wouldn’t see that as an enormous advantage over the competition??? Of course it is. That doesn’t mean you’re wrong at all, they have to play the other teams that occupy the MCG as home also. It’s also not any fault of Collingwood to have the biggest supporter base in the land either. Both points can be correct at the same time. But there’s no doubt it’s an enormous advantage every year for Collingwood, Richmond, Melbourne and Hawthorn….

  @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.
