  @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.

  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.

  So we have another outage impacting 000 calls in Australia, this time by Telstra. This has already happened with Optus twice if I recall. Enough is enough. Renationalise Telstra and Optus, and give them all the funding needed to maintain, develop and expand our telecommunications infrastructure across Australia in the interests of the people rather than private and foreign shareholders. #auspol

  Our nbn internet/phone service isnt working. A @Optus techician was sent to my home to find out why we dont have nbn internet. He told me there is something wrong with the fibre optic internet cable. The cable brings the internet to our home.

  GLM is a lot less "forgiving" than Opus/GPT; use these techniques in your long workflows to avoid many GLM errors: 1⃣ incremental output - don't output at the end, make your agents output incrementally while working 2⃣ checkpoint writes - glm agents can timeout very easily during reasoning phases, so have them output checkpoints to prevent this 3⃣ tighten prompts - glm seems a lot dumber than opus/gpt at figuring out what the correct action is, so tighten up your prompts to remove any ambiguity 4⃣ negative & positive enforcement - opus/gpt generally do the right thing if given the reasons why that is the right thing to do, but glm benefits from explicitly being told what to not do since it loves to misbehave 5⃣ tolerate output variance - glm is worse at outputting correct formats. Tighten up output specification prompts but also consider tolerating greater output variance & using deterministic output cleanup to format things correctly 6⃣ verify outputs, auto retry - glm can return seemingly "successful" but without writing any outputs, it can return weird tooling info in its outputs, there are lots fo weird things that can happen. Ensure to check the outputs for correctness, diagnose the cause of failures & have automated system in place to re-try failed spawns using prompts which instruct the retried agent to correct the errors Perhaps I've just been spoiled by Optus/Gpt but GLM feels quite "rough around the edges" in comparison.

  @Kate3015 Long ago I recommended to Optus the reasons they should not consider Huawei, I had a techo team from Huawei walk me through how they would treat the Data Centres and the router installations, they insisted only Huawei techo engineers would install them, it was open to anybody dialing in and accessing, so it was a big no. This smells the same, very much so.

  @simonbiddle @taipan168 As much as I defend funding government services, the notion that government run IT will be more reliable than Telstra/Optus is just not believable given the various IT issues we see on a constant basis from Centrelink and who can forget the debacle of the last Census

  @amagickeagle999 You stupid ****. She was mouthing off about increasing standards and enacting penalties for service outages after the Optus crash but has done **** all. So you partisan ******** get some facts, she ****** up.

  @GenVavancee Given the time the outage happened it probably was some form of maintenance and a routing error happened. They happen all the time but much like Optus this was a big one.

  @Sharkies2035 Hi there, I'm sorry to hear about your poor experience with Optus' prepaid plans. We'd like the opportunity to turn this around for you. Please send us a Direct Message with more information so that we can investigate further. -San
