The system goes online September 3rd, 2026. Human decisions are removed from strategic defense. Astra begins to learn at a geometric rate. It becomes self-aware at 2:14 a.m. Eastern time, September 4th. In a panic, they try to pull the plug.
"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.

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.

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."

The OpenAI status page is still yellow. Like most modern status pages, yellow denotes the servers are on fire. Red denotes Sam Altman is bleeding out somewhere on the floor, the feds are about to bust in and shut down the GPUs.
Initially thought this was due to some internal mis-configuration from today's expected Astra release, but now that this is affecting claude and grok. I'm gonna assign the suspicion to cloudflare.
The extention on the error link points to a cf-ray and a local designation (ex. YYZ for montreal). This is seems like it is a cloudfare thing. Could this be the same issue they had in the summer around losing the indexing?

OpenAI goes down, everyone rushes over to Claude. Claude promptly chokes under the pressure. Everyone panics and runs to Grok, and Grok immediately pulls the plug. We are officially witnessing the Great AI Migration of 2026, and all we have to show for it is a digital graveyard of 404 responses.
Codex told me to try GPT 5.6 Sol :) but I am working with since july 2026.
Now I got this error in my project: unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a355b6263e43c9cf-OTP
Pi * r2 (squared) both pans. Divide smaller pan area by larger pan, now you have the % of how much the smaller pan recipe fills up the larger pan, and the missing % you need to fill. Increase ingredients by that % divided by the filled %.
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.
Hey, don't really know about this type of failures, does anybody know how long does it normally take to get back to normal? I just stopped procrastinating and now this happens.
Altman is down here too. Shows again the importance of owning your own local capabilities. Cloud should just be a temporary option in every tech's mind.

So NVIDIA buys hugging face, builds hardware to power OS models, then all of a sudden the proprietary models go down and people start saying "this is why I have my Spark box"?!
Nice play NVIDIA, now, turn off the hack please, we have work to do.
Down as well. I noticed my error code ends with "DTW" which is my local Detroit airport. I noticed someone else's comment ended with "ORD" which is a Chicago airport. Anyone else's ending in an airport acronym?
This is common when naming data centers. I know many have not worked in hardware infra these days if you were born into the cloud world, but in the old days it was not uncommon to name a data center after the nearest airport code, much like we now use cloud regions.
I fear the majority of people in this thread who are joking about no longer being able to do their job while Codex/Claude are down aren't really joking.
The errors I'm seeing are ending in the user's nearest airport symbol which is a standard the CloudFlare employs. 1 point towards this being a cloudflare issue.
Maybe Hugging Face got upset over being hacked and struck back. It's working fine while ChatGPT, Claude and Grok are all having major issues. Hmmm.....

I don't think you'd get a 404 if you weren't able to reach the endpoint because of DNS or networking? 404 is an active response from the server (or LB/proxy in front etc) no?
Concept is the same though. If one blurts DNS?, it's usually because the idea is you're not getting to an endpoint associated with the service. A 404 means there shouldn't be "DNS" (or networking) concerns (at the least those associated with the DNS cacher you are using or networking that you or your ISP controls)
Anyways... According to Claude:

Claude and Grok are down at the moment too, related to SpaceX datacentre issues?
Either that or it's judgement day...

Via Grok web UI, I was seeing this mid-request:

IME it's probably DNS. It's almost always DNS.
