  @vaughan_k @Optus I don’t know exactly but I did eventually login on my computer. Can’t get the app to download my bills on my phone. But my bills look different so I may have been migrated to a different billing system.

  @therevaknight Because of Government incompetence, they had no simple backup system, they made NO allowances for technological failure, complexity is the enemy of reliable; the reliability issue was known (ref previous OPTUS outage). NO REDUNDANCY for critical infrastructure! @heidimur

  @matt_barrie @van00sa And the Optus network went down right after Albanese visited Beijing in November 2023.

  Let’s forget the umpiring, taunting and constant booing of this underrated crowd, what’s the go with this Optus stadium deck, the worst ground in the AFL currently, on par with what was dished up for origin last night. Awful. #aflfreoswans

  @OperationalInc1 at a very minimum you should need both Telstra *and* Optus to go down, no?

  @NoticerNews Same reason for the recent Optus outage. This woke CEO & Labor government needs to swing.

  A guy moved into a new apartment. Only “official” internet was FTTN NBN — $90/month for a pathetic 30 Mbps down max. He called Telstra and Optus. Both said “5G Fixed Wireless not available at your address.” He checked a cell tower map anyway. Half a dozen towers within a couple km. Bought a GL.iNet GL-X3000NR 5G router + built a DIY 4x4 MIMO LPDA external antenna. Result? 800 Mbps download / 170 Mbps upload. 25x faster. $75/month. Same building. Here’s exactly how he did it 🧵

  @OMGTheMess It only happened recently with Optus. Anika Wells didn’t fix it, did she?

  @7NewsBrisbane Why doesn’t 000 have an alternative number as a backup run by? Maybe Optus or Tpg or Vodafone? How does a company or a business run with just one solution? 000 is incompetent.

  @FelixCLC_ What's been the biggest problem you've faced using Optus with hardware design ?

  Ask Grok: Can ISPs block VOIP? 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. TCP/IP allows spam filters at the node level. This is one small example. TCP/IP remains neutral and ethical.
