We had a routing error within our infra that caused issues for some of our products. It was not related to the Astra launch. We don't comment on other providers' outages.

It is a common system in all kinds of emergency response scenarios, including local emergency services (fire/police/ambulance) and it scales all the way to massive disasters.
It is especially useful to clarify command structures when multiple response entities need to coordinate. That is true even within organizations like public companies, where the reporting structures may be distinct.

My hunch is everyone saw that openai and Claude were down and checked for Gemini too. I was using Gemini the whole time this happened without a blip so it certainly wasn't down in my region at least. 3.8 flash is pretty good and didn't miss a beat.

The capital letters don't make this astonishing. The padmapper vs. craigslist debate was nearly 15 years ago, most people were on craigslist's side (including me) and it was about somebody who was running a site in a less optimal but more human way vs. some startup looking for hockey-sticks.
But I was literally simping for the billionaire (maybe not quite yet then, don't know for sure if he managed it since) against scrapers. They were very much for-profit scrapers, unlike nitter, but the truth is the truth.
The only reason I support scraping Twitter is because it's yet another communications monopoly that was endlessly pushed on us by governments and massive corporations, even though it never made money, and once it finally got traction its priorities were to trash interop and manipulate content. The government should be dictating an interop protocol and expecting everyone to follow it, and instead it is encouraging media monopolies because they are an end run around the first amendment.
If the government created interop protocols for rental property, I'd have been against craigslist. Instead, it seemed very much like some startup play to steal craigslist's content to hopefully bury them, then sell on a valuation that included abusing their new monopoly and making us very much miss craigslist.
Sadly, facebook corralled and trained so many people for so long that their marketplace eventually killed craigslist for most things anyway (didn't have to buy padmapper after all.)

This whole thing makes me thing about a passage in Dune where they mentioned the Spacing Guild transported entire fleets of ships in isolated compartments and leaving said compartments was a capital offense. This way, entire militaries of mortal enemies were shipped to battlefield, with nothing but bulkheads separating each other.

Still leaves me questioning how anyone could wage war. If the Harkonens could barely afford it, nobody can.
Also wondering if the Guild charges different rates for goods vs military. What is worth the brutal intergalactic shipping prices that you would not develop local industry to create it? Surely nobody is moving grain or ore, yet the Guild ships are portrayed as comically massive.
Comment by abtinf 3 days ago
The guild would not allow any action to jeopardize the flow of spice. Thus any attack on Dune is implicitly sanctioned, notwithstanding their spice trade with the Fremen.
Comment by jaybrendansmith 2 days ago
Comment by torginus 2 days ago
This playbook has only flipped due to a lot of cheap tech (and the machinery to make them) coming in uncotrollably to these countries has put them on a much more equal playing field.
Since the Guild controls what comes in, they can avoid this scenario from happening. They can control who can have what, and who can make what. Which I think is one of the true, deep explanations of why military tech in Dune is so weird and inefficient - essentially the efficiency and power of a weapon is dictated by how much the Guild charges for shipping them if they allow you to, at all. Which is how you end up with dudes with swords. It gives an idea of the level of technology in the universe that you can equip said dude with a nigh-impenetrable shield that fits in a belt buckle. I guess that's the result of optimizing for Guild transit fees, not real-world power.
Really it's not exactly a novel idea, but as I think more about it, it's uncanny how Dune (at least initially) is basically the fantasy Suez crisis and what followed. It explores the power dynamics very well, how factions can hold humanity hostage without firing a single shot, and how what they don't bother controlling comes to bite them in the ass.
> How could anyone wage war like this? The defenders will always outnumber the attackers.
Which is exactly what ends up happening, but it does take a bunch of extraordinary events.

> All of these endpoints use existing providers with decades-long history at this point
That is just factually inaccurate. Their data centers aren't old and they lease a lot of compute from companies that didn't exist 5 years ago.
Comment by usernomdeguerre 3 days ago
They all transit the same wires as all other traffic. Copy them at any regional bottleneck. https://en.wikipedia.org/wiki/Room_641A. Additionally, i'd admit that maybe someone(s) at these companies knows. But if we think there isn't any person who would agree to do this then I think we're being naive.
> Their data centers aren't old and they lease a lot of compute...
Again, they transit the same wires as everyone else. Here i'll also add that these companies have been actively courting government relationships (and Anthropic attempting to repair damaged ones), why would they stand on principles here and not any of the other many frontlines they've visibly acquiesced?
I just think it's easier to re-route their traffic than, as you say, touch every single datacenter and its employees in some way.
Comment by strictnein 3 days ago
Oh, is that all?
> Again, they transit the same wires as everyone else
Which shared wires does Google's traffic go across? Do they share that network with others or do they not function as a Tier 1 network? How about Amazon? And the NSA is doing deep packet inspection of all the traffic going to these places to pull out the data they are interested in? What systems allow them to do this at the scale that would be necessary to accomplish this task? Anthropic, OpenAI, etc have their models hosted and provided by these and other Internet giants. So you now have to be able to somehow also get access to every "regional bottleneck" that those places have. Google has 40+ regions alone, as does Amazon. And each of these regions don't just have a single point of inbound/outbound traffic, so now you're over 200-300 points of interception that you would need just to grab the data you're suggesting they are.
And that's just the start of it. When I use Vertex or the Bedrock, my AI API requests from my instances doesn't leave their networks. So where does that traffic get intercepted?
> I just think it's easier to re-route their traffic than, as you say, touch every single datacenter and its employees in some way.
That would be really, really loud and really obvious. Messing with routes like that is very easily detectable.
Or, maybe, they don't care about this traffic at all and doing all of the huge amount of work necessary to accomplish what you're proposing isn't worth 0.1% of the effort it would require.
If the government needs the chat messages, the companies are already saving them. They can just request them through a variety of legal means. None of this vast conspiracy nonsense is needed. Just a couple lawyers and a willing judge. The NSA stopped their collection of phone metadata because they can just request what they need from the telecoms directly.

Also, OpenAI is saying what caused it:
> "A routing error starting around 7:43 am PT on Thursday, September 3, made ChatGPT and Codex unavailable for some users across platforms"
Anthropic stated their issue started earlier:
> "The company began alerting about a “partial outage” at 6:23 am PT on Thursday that involved “elevated errors on requests to Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5.”
I don't get why everyone reaches for an extraordinary explanation when the ordinary will do: both of these companies have quite a bit of downtime.

With AI it's even easier to trigger problems like you say. Capacity is so constrained by compute that outages are common. Because outages are common people/AI develop failover systems in their harness. When a big system has issues, suddenly everyone has issues.
It's almost an expected emergent behavior.

Using an agent-agnostic harness like Pi switching is trivial - I run into occasional disconnects and slowdown and switch quite easily.

Anthropic: 6:23 am PT.
OpenAI: 7:43 am PT.
Watched it happen. Doesn't look like traffic moving off OpenAI took out the others. Looked like the opposite. The Anthropic thread was initially chock full of marketing accounts claiming "Last straw! I finally moved to Codex and I'm so happy! No problems there!" - and then they all got deleted when Codex went down too.

Anyways... According to Claude:
"Yes, there is a multi-provider outage happening today. Downdetector is reporting problems affecting OpenAI, Claude, Grok, and Cursor, with Grok and Claude reports starting around 9:00 am ET and OpenAI reports following around 10:30 am ET. Zero Hedge
On the Anthropic side, users saw a spike in errors starting around 9:40 am EDT across models including Mythos 5.1, Fable 5.1, Mythos 5, Fable 5, Opus 5, Opus 4.8 and Opus 4.6, and Anthropic's status page confirmed elevated error rates for multiple models. The company says it has found the cause and is working on a fix, with Claude Code and Claude Chat hit hardest. The visible symptom for many people is a "Due to unexpected capacity constraints" message or a "Claude is at capacity" error. thenews Zero Hedge
OpenAI is showing elevated errors across ChatGPT and Codex, with confirmed issues on components like Voice mode and Login, though StatusGator now marks that outage as resolved. statusgator
Nobody has published a shared root cause yet, so it is unclear whether these are linked or just coincidental capacity problems landing on the same morning. If you want live status, the direct sources are status.anthropic.com and status.openai.com."

20 / 48 = .42, I'm missing .58 of the pan. .58 / .42 is 1.38. My recipe needs 2.38x the original to fill the larger pie pan.

Anthropic is down a lot regardless, and in this case only specific models were affected.
xAI probably couldn't handle the extra traffic it was getting from the other two.
