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

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.
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.
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.

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.
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 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.

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)

Don't most of those use AWS?
apparently it shows lot of reports for AWS on downdetector ..
30 mins and they still havent figured it out .. people are gonna loose their jobs trying to figure this out .. 30mins is too long when millions use it
https://status.x.ai
Claude and Grok are down at the moment too, related to SpaceX datacentre issues?
Either that or it's judgement day...
Agreed, no reported Cloudfare, Azure, or AWS outtages.
I am working fine with Claude.
My existing sessions are working fine but I cannot create new ones.
status page shows irregularities .. https://status.claude.com/
It is down for me too. I just get this error:
unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a355957b4b8210f2-ORD
Claude is flakey atm too, as is Grok. I wonder if one LLM going down causes a surge in traffic to the others.
https://status.claude.com/
Via Grok web UI, I was seeing this mid-request:
> Grok has been disconnected. Please try reconnecting.
Traffic surges shouldn't result in 404s, though.
IME it's probably DNS. It's almost always DNS.

I am only seeing one session work, but all other sessions are not working or proceeding. So I can only work in one chat session.
It still down, showing 404 in India as well. Looks like this is global .. so we all jumping the ship then? Is Altman still alive, or did he choke?
Well, its been fun lads. Back to my normie job. Oh no, now i cant tell people im a software dev..
hahahahahahaha. Sad
- just imagine what kind of chaos would be unleashed if by some magic it and every single LLM model permanently went down
- i think it would be one of the biggest events in this century
At this point in adoption, most people in the world wouldn’t notice.

yes daydreaming and get hammered and the whole train of decision are on the way
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?
Mine is ending with IST, which is the new Istanbul airport, weird indeed.
Hm not sure what that means for us, but very odd.
Wow mine ends in EWR...that's the newark airport which is not the closest, but a close airport to me. Hmm
Yeah mine is showing ATL
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.

which ended up tripping on itself and bringing down its own servers too in the process

I can run one agent but no more than that - 404 service error.
AWS cost alert fired maybe?
Any idea when it's going to be back?

Does anybody know when will the servers rise
Same here
I guess back to pen and paper then
main sites also down now atp

ITS BACK UP IN INDIA
This thread feels like family.
down in Spain w/ 404
ChatGPT died
still down for me ..in India.
It's back！！！！！
We're back bois
only on one node across the mesh and others still up... let's see how long they've got until same
Is it DNS or BGP?
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?
I imagine OpenAI network is a tad more complex than a box with a public IP.
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)
Great! Was in the middle of something. :)
and i just stopped procrastinating :)
hahaha
at least the Ollama cloud is still alive :D
I can run 1 agent, but no more than that.
only for one node in the mesh tho... let's see how long others will continue until same issue
damn chatgpt is down, i guess ill use claude then breh
darn, i was hoping to get advice on how to get my MIL to leave my house lol
Кодекс сдох :(
i got the same 404 codex error as well
ironic astra was releasing today... maybe some test run?

ironic today astra was releasing.... maybe some test run?
probably the cause, because AGI still can't get releases right.
