do you generate training data for claude as a job?
Why are we all depending on one entity for it all to work? Makes me mad.
I hope Reticulum gains traction.

Buddy, read the room. Just because it works for you doesn't mean it works for everyone. ESPECIALLY if the suggested issue here is, indeed, with Cloudflare.
You stepped in the room real stinky here. What’s with the attitude?
For once it’s appropriately used.

Wow thanks Tom. I love you
The End
So not a coincidence, one went down first and users migrated causing further DOS. At least that's my guess.
i also finally installed opencode and switched its model to muse 1.3
both are decent.
It looks like there's no response available for this search. Try asking something else.
Gemini is what I mostly use (good enough, basically free - or massively generous free limits, and to me Google as a company is a LOT less objectionable than all the US-based alternatives), but I don't recall it ever saying that.
OTOH, my basic assumption online is that there is no privacy, and free AI in exchange for acknowledged lack of privacy seems fair enough.
E.g. say you chose Sol as your default in Cursor, but Opus is your 2nd choice, it's going to give up on Sol after a few tries and switch to Opus
Or you have copilot code reviews set up, and it falls back
Etc
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.
Edit: Updated per valleyer's suggestion.
And then a local swarm noticed and disagreed and took it down.

The Waluigi Effect: After you train an LLM to satisfy a desirable property, then it's easier to elicit the chatbot into satisfying the exact opposite property.
https://www.lesswrong.com/posts/D7PumeYTDPfBTp3i7/the-waluig...
I'm curious what other things you would argue influences an LLM's behavior.
I am also generally one to trust the claims of the people who train the models, though you're welcome to the highly improbable belief that they operate in a fantasy world.
The things we say publicly actually do matter and the post-modern descent into absurdity and nihilism has tangible negative consequences?
More likely just cascading overload though: "Never attribute to malice what can be explained by incompetence", or in this case, "growing as fast as possible"
I'd bet more on this. For one none of the coding tools have exponential backoff on retries
Amazon starts going slow so some percentage switches to Google, some switch to Grok, now all of them are slow.
Claude and Grok are down at the moment too, related to SpaceX datacentre issues?
Either that or it's judgement day...
Oh the humanity (and the Humanities)!
"Um, I, uh, didn't get anything done yesterday."
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."
Ads Platform? still in the green with no incidents.
I'm also aware that they have overlap in some areas on data centers.

Via Grok web UI, I was seeing this mid-request:
> Grok has been disconnected. Please try reconnecting.
IME it's probably DNS. It's almost always DNS.

For any single application, it's smart. In aggregate, it's stupid.
In codex app and chat.com gives 404
And even worse if its just a few computers run by a few people - as they will bring down many others depending on them.

› OK
■ Conversation interrupted - tell the model what to do differently. Something went wrong? Hit `/feedback` to report the issue.
But, also, Claude has been working fine for me all morning.

It's much cheaper and has replaced Sonnet 5 for me.
Small pan area: 20 sq cm Larger pan: 48 sq cm
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.
edit: actually, you cannot even log into your OpenAI developer account. Something's wrong.
Ends in BRU for Brussels
In think that is a global error
