^^^^ this. I work for a big company (15k engineers). Trying to use anything that is not TCP or UDP simply doesnt work here. For years, even UDP was blocked and the answer we got was always "why are you using UDP, use TCP instead". Yep you read that right. Most of these folks are very short sighted or narrow minded. We tried to use SCTP for one project, major blunder. Zero support from network teams. Sctp is blocked everywhere. All their custom software and scripts for network deployments only work with tcp and udp. And they will not change that. And that comes from higher ups the ppl in charge. They are set in there ways and will not budge. As for as QUIC support? Never gonna happen here.
I have also had to deal with UDP getting blocked by a middle box before. It is rare now across the internet but you never know what intranet grey beards can do.
And UDP hole punching is a crutch for the fact that we still use IPv4.
I'm one of a few people who can say they used SCTP for its original purpose, SIGTRAN transmission of Signaling System 7 call setup data over IPSec tunnels. It was really cool seeing SS7 packets in the wireshark dumps.
These people havent deployed anything to a production environment that requires reliability and support. For that, you need a real software engineer to take apart the mess of vibe coded kludge and create real software that can actually be given to people to use. I wouldnt worry about this. Vibe coding trend is already on its way out as people discover this.
I've been tracking usage in my first month of "20x" Max (which was, unfortunately, this month). Depending on how this usage is amortised (working days, which is what matters to me, or 5 hour periods, or I guess, now weeks..?) their marketing material has been varying degrees of false. This has ranged from 'a bit false' to 'extremely false'.
That is true both on a relative scale ("20x") compared to my previous use of the $20 plan, but - more dishonestly, in my opinion - absolutely false when comparing my (minimal, single-session, tiny codebase) usage to the approximate usage numbers quoted in the marketing materials. The actual usage provided has regularly been 10% of the quoted allowance before caps are hit.
I have had responses from their CS team, having pointed this out, in the hope they would _at least_ flag to users times that usage limits are dramatically lower so that I can plan my working day a little better. I haven't received any sort of acknowledgement of the mismatch between marketing copy and delivered product, beyond promised "future fixes". I have, of course, pointed out that promised and hypothetical future fixes do not have any bearing on a period of paid usage that exists in the past. No dice!
I'm, unfortunately, a UK customer, and from my research any sort of recourse is pretty limited. But it has - without question - been one of the least pleasant customer experiences I've had with a company in some time, even allowing for Anthropic experiencing extremely high-growth.
Claude Code Router has been a Godsend for my usage level. I'm not sure I can justify the time and effort to care and pursue Anthropic's functional bait-and-switch offering more than I already have, because being annoyed about things doesn't make me happy.
But I completely second this: it's not acceptable to sell customers a certain amount of a thing - then and deliver another - and I hope US customers (who I believe should have more recourse) take action. There are few other industries where "it's a language and compute black box!" would be a reasonable defence, and I think it sets a really bad precedent going forward for LLM providers.
One might imagine that Anthropic's recent ~$200m US gov contract (iirc) might allow for a bit of spare cash to, for example, provide customers with the product they paid for (let alone refund them, where necessary) but that does not seem to be the case.
It makes me sad to see a great product undermined like this, which is, I think, a feeling lots of people share. If anyone is actually working towards wider recourse, and would find my (UK) usage data useful, they're very welcome to get in touch.
Can't you just use a sphere with a small single flat side made out of heavier material? That would only ever come to rest the same way every single time.
