  Optus 4G has been rubbish all afternoon. Not completely broken, just bad. I presume it’s DNS somehow.

  @ERN_Malleyscrub @sgorolay @Optus That trick never works 😁

  Oh, but @triplej is far-less-national than I understood. Still a big chunk of this drive where neither broadcast radio or @optus signal penetrate.

  @MikeCarlton01 @Telstra That would be vodafone followed by optus and then telstra. Before anyone comes after me, vodafone went down for several months in 2010/2011, optus had a data breach in 2022 that affected nearly 10 million customers. Telstra just inconvenienced people.

  @nicko_316 Thats bad news for Brizvegas if you’re right. Freo will be favourites in that match up at Optus.

  @EVERALDATLARGE Many have said their Telstra provider phone worked but not their Optus. I even saw one question regarding Vodafone. Is it a provider issue perhaps?

  @Tiger27745120 Thank the lord, thought i was the only one. am on the phone to optus now. The day before the ausalert message i was forced to update my phone. a S25 Ultra samsung. Ever since that and simultaneously the AUSALERT message i have nothing but connectivity issues.

  @stupidtechtakes reminds me of the optus outage (**** optus they killed my xiaomi 15 from connecting to optus networks)

  @CharlesSzulc Telstra will appear before a Senate inquiry into its outage, starting next Friday. Senator Henderson is involved in the (apparently ongoing) Optus one. It'll be be interesting if she now asks questions of Telstra, as will be forthcoming media reports.

  @PaulBongiorno Oh woe is me ! Just purchase a sim card supported by Optus [this is redundancy contingency] when Telstra goes off line swap out their sim & slot in the backup & vice versa. Alteratively purchase a dual sim phone which allows you to switch between service providers

  @jfwfreo @D_LittleproudMP Exactly. I live remotely, and the local tower broke down. It took 3 weeks for Optus to arrive. Meanwhile I used the local pay phone most days to conduct business and to phone concerned friends and relatives. Littleproud has no idea how the remote live. He’s just another National

  @StMaryMacKiller So bad the iPad has an Optus chip and the house has been in Starlink for years

  @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.
