  @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.

  @thmsenglsh i used to work at telstra and we had even more data breaches and outages than optus did but telstras like besties with every australian media outlet and funds alot of their services so everyone just bags on optus instead, telstra genuinely sucks

  @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).

  @dwjorgeb Im still all in on Claude. Fable I think is a bit slow I just use Optus ultra for most things

  @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.

  @7_columns @Andrew_McCallum If you listened to her, the government mandated after the Optus issue, that with emergencies, the people using the network that is down, should be switched to a working network. She said she wanted to test that her phone went to Optus if Telstra didn’t work. It didn’t, and that is important.

  @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.

  @Birdsperch Clearly no contingency for terrestrial fail [all eggs in one basket] even with satellite backup downlink distribution relies on terrestrial bearers (circuits), Even Optus with satellite support incorporates terrestrial distribution -Contingency planning is key & costs money

  @heidimur This isn’t just about Telstra. We saw similar issues with Optus. If our emergency communications and critical infrastructure are meant to be resilient, why do single network outages continue to have such widespread impacts? It’s time to review whether our redundancy is truly independent, or whether we’re relying on backups that share the same points of failure.

  🔴 Telstra CEO faces parliamentary inquiry over nationwide outage affecting emergency calls, payments Telstra chief executive Vicki Brady will testify Friday before an emergency parliamentary inquiry into last week's outage that knocked out triple zero emergency calls, disrupted payment systems, and stopped trains in two Australian states. Greens communication spokesperson Sarah Hanson-Young said: "Telstra, just like Optus, has put their profits ahead of public safety and public service for far too long, and the law allows them to." • Telstra accepting compensation claims from affected customers and small businesses with supporting evidence
