  @mdtlion FYI! The Labor Government have STILL NOT released the findings of the OPTUS OUTAGE in September 2025. DONT hold your breath for answers folks! CHEERS ANNIKA!

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

  @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.

  @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….

  @heidimur In WA Transporth uses Fibre that runs thought every station and Private Wireless (LTE/4.9G): Transperth doesn't use Telstra or Optus for train-to-ground data. They built a custom, secure wireless network with 160+ dedicated radio masts along the tracks using licensed spectrum.

  @matt_barrie @van00sa And Optus went down right after Albanese visited Beijing in July last year.

  @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.

  @7NewsMelbourne But you still have to go with an Aus provider as they own the leases on the spectrum it uses and are the only ones to provide service in buildings and high density areas. Optus & Telstra already can provide sms via starlink with calls and data in a few years. So no - the major telcos are not under threat.

  @burkylie12 Well done Telstra for the massive Outage 👏 👍 Telstra supporting the Crusification of Optus for the same. It's certainly a clear display for the idiots that want a Cashless 💸 Society.
