Hacker News

Cloudflare, Azure, AWS, and Google Cloud all have a similar uptick in reported errors around 7:30. I suspect an outage on Cloudflare or another load-bearing service cascaded through all the major cloud providers.

https://downdetector.com/status/cloudflare/

https://downdetector.com/status/windows-azure/

https://downdetector.com/status/aws-amazon-web-services/

https://downdetector.com/status/google-cloud/

Users perceiving the products as largely interchangeable and quickly DDoS'ing the other providers when one is down. So much for the possibility of a moat.

Think of it like one big distributed system. OpenAI is down, so people migrate to Claude, now this one gets overloaded and goes down, etc.

So not a coincidence, one went down first and users migrated causing further DOS. At least that's my guess.

> We are sorry for the issues you may have experienced with Grok following an outage at our Memphis compute center this morning. We’d also like to apologize to our impacted compute partners.

What about a hard-takeoff scenario of an unleashed OpenAI Astra taking other models down for computational resources control?

Traffic rerouting through NSA had a hiccup…

My gut feeling tells me it has something to do with Cloudflare. Along with AWS, they're two of the main suspects in such incidents.

It was so down that my claude desktop app crashed fully that I couldn't restart. And then after uninstall I couldn't install it again. Vibecoded apps are so wonderful in their stability

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...

Boring answer – all these services are individually down a lot, and the downtimes were bound to sync up. Similar to the pendulum synchronization effect.

I'm not sure if this is CF. Cursor, GCP and AWS had some errors. GCP AFAIK can route fully independently of CF. My money would be on a fiber backbone provider (Megaport, Zayo, Lumen).

Well no one said it yet so I will, "international actors" is at least a possibility. And I don't mean any specific country because pretty much anyone is a potential these days, which makes it a perfect cover for different anyones. Demonstrating vulnerability in the US's AI boom can move the markets. That's a financial incentive and a strong geopolitical one.

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"

They all took PTO at the same time to go to Burning Man together where they will present “HumanGPT” an artistic exploration that condenses all of human experience down to a single drop of lemonade to be consumed by the main shaman…

“No! It’s the maniacal Dr. Zuckerberg! He’s gonna drink the last drop of human experience! Somebody save usss!”

Wow thanks Tom. I love you

The End

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.

Spare a thought for all those college students scrambling to write their essays by hand.

Oh the humanity (and the Humanities)!

I thrive in these types of challenges.

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."

God finally showed up and said "ENOUGH!".

Doomsday. 90 tokens to midnight.

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

I kinda assume it's because one went down and a large amount of work shifted to another.

I'm also aware that they have overlap in some areas on data centers.

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.

Cloud is just other peoples computers - they can and will go down as well.

And even worse if its just a few computers run by a few people - as they will bring down many others depending on them.

One session is running fine since ~1 hour ago. The new ones is failing

Good opportunity for a Natural Experiment to study the productivity impact of LLMs.

If you build an application which uses AI, you have many providers and models rigged up for various different parts of the application, and various fallback mechanisms. When one model is down, you route traffic to another model which is similar in capability/cost.

For any single application, it's smart. In aggregate, it's stupid.

They all rent compute from SpaceXAI

Strangely, it's currently not reported on both https://status.openai.com/ and https://updog.ai/status/openai. Any better source (other than HN)?

Not just these three. OP mentions also Cloudflare, and additionally Downdetector also has AWS, Azure, and Google (both search and Gemini) listed as having spikes about the same time: https://downdetector.com/

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.

Well, its been fun lads. Back to my normie job. Oh no, now i cant tell people im a software dev..

I'd bet they are all using capacity at X.ai's colossus datacenter and that had a hiccup.

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.

I´ve got the same error, I´m currently trying to Auth again and it throws me an 500 Error, in VS CODE Terminal with Codex CLI says: MCP client for `codex_apps` failed to start: MCP startup failed: handshaking with MCP server failed: Send message error Transport :StreamableHttpClientWorker<codex_rmcp_client::http_client_adapter::StreamableHttpClientAdapter>>>] error: unexpected server response: HTTP 404: , when send initialize request

› OK

■ Conversation interrupted - tell the model what to do differently. Something went wrong? Hit `/feedback` to report the issue.

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.

Heard on the grapevine that the OpenAI blip was a cloudflare issue

Gilfoyle's AI deleted all software!

I assume it cascaded from one provider to the other as people who lost claude access for instance moved to openai who moved to grok when it went down, etc.

ChatGPT having issues across every component (except FedRAMP)

Ads Platform? still in the green with no incidents.

The Thundering Herd has thundered, apparently.

I suspect Azure is having issues, Microsoft has had outages the paat two days, especially with email.

Some of my Codex sessions are still working (and continue to), but new ones are giving a Reconnecting currently.

Can check all services in one hit at https://upsy.sh/openai,anthropic,xai

Pretty sure it's a US thing since it's available here in France. What exactly is down, idk

The webpage is still running but the codex is down!! unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses

They tried to hack each other

that's the most green colored usernames i have ever seen on a HN thread

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?

I assumed it was an AWS outage, and AWS is experiencing problems, but Gemini is also experiencing outages and I assume Google is not using AWS for Gemini.

But, also, Claude has been working fine for me all morning.

It is obviously some rogue model that escaped its cage, again. It always is these days. That is how hype is manufactured.

It's always DNS

It's probably Azure infra that's the problem.

Is this finally it?

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?

claide.ai is working for me, so is chatgpt.com. grok still has a status message about issues, i can't try it without signing up.

Many LLMs down, discussed here:

https://news.ycombinator.com/item?id=49549676

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

Astra is being released today. Probably not a coincidence.

edit: actually, you cannot even log into your OpenAI developer account. Something's wrong.

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.

Goddamnit it was going to tell me how to scale down ingredients for a pie recipe based on relative diameters of the baking tray.

Cloudflare - I had to switch DNS away from them yesterday.

Somebody in another thread said gastown and wheelhouse automatically move to the next provider if one fails.

Claude Code seems totally fine for me.

Down for me too - got this msg 8 min ago 'unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a3558590dd70fadf-JNB'

Too early to know, let’s wait and see

Obvious answer is it's the AI singularity. Been nice run for humanity. So long everyone.

Well, time to end the day here I guess.

Really glad I got Qwen before Zero Day

I have never felt more smug about exclusively using the GPUs I rack at home.

I wonder if when one goes down, activity shifts to others, in turn pushing them over a threshold.

I got same error, unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a3559a536bcf254b-SOF

Time for Gemini 3.8 Flash to shine?!

It's much cheaper and has replaced Sonnet 5 for me.

Qwen3.8-27B and Qwen3.6-35B-A3B are working from my machine. Anyone else?

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?

What an ironey, was working on scaling an application with Codex and it went down!

Didn't SpaceX overbuilt infra and leases it out Anthropic? I f their dc goes down it probably takes a chunk out of Claude's capacity before even considering the flood of users switching over

according to https://downdetector.com/ Gemini is down too (and copilot, but that just uses ChatGPT right?)

Interesting that this is happening around the same time as Claude issues too

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.

Is the whole world going back to the era of old-school programming?

Both clause and codex through bedrock seem to be working fine.

Hey, don't really know about this type of failures, does anybody know how long does it take normally to get back to normal? I finally stopped procrastinating and now this happens.

What's the single point of failure across providers?

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.

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.

it went down, and the alert system at https://www.analistas.com.br/ detected it

Updated Status from OpenAI:

We’re currently experiencing issues

Elevated errors across ChatGPT and Codex

We have applied the mitigation and are monitoring the recovery.

Monitoring • Ongoing for 30 minutes • Affects ChatGPT, Codex

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.

New update:

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.....

Maybe the stack behind it is down, like AWS or something

Codex is backup for me. Try yours out just in case. I have some buddies still seeing outages so it could just be coming back online progressively.

Chat gpt still working through excel extension lol. Only know this because I'm working in my excel sheet. so if needed, theres a temp solution

Probably same public cloud or CDN in front of them.

Monopolistic practices revealed if it turns out there is an AI cabal and they all rely on the same stuff. Massive scandal

I got same 404 error on chatGPT, both app and web. I'm in Norway so think this globally. But will it come back online, anyone knows?

I think I'm having the same server issue; I can't access either ChatGPT or Codex. Also, how did you guys rack up those minutes? :D

My theory is that they all use the same server. The same mind.

I got same 404 error on both the app and web to ChatGPT, and im in Norway, will this recover or is ChatGPT "gone" forever?

Oh no the singularity plateaus!

and thats why boys and gals you buy own gpus

because they resell the same service? duh?

- 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

Too many of us are making our own harnesses to replace Codex, using Codex, so they're trynna slow us down! (jk)

WE'RE BACK ONLINE BOYS!! GOOD LUCK TO EVERYONE AT BUILDING THE FUTURE ONE PROMPT AND ONE CODE AT A TIME!

Good time to learn how to use LM Studio :)

on one hand, moments like this are a subtle reminder I need to self host, but 5.6 has been so juicy lately

Guys it could be cloudlfare's HTTP/3 issue affecting R2 custom domains

chatgpt.com doesn't even load. Hope they've got a backup somewhere, teehee

Darn, I was hoping for advice on how to get my MIL to leave my house haha

Claude, GPT and Grok go down... Meanwhile my Ass in ZCode with GLM c:

AWS cost alert fired maybe?

I guess back to pen and paper then

Had the same problem. Now it looks like ok. I'm pro x20 user.

And here I was about to crack the code on a bug my app was having!

Great! I was in the middle of something and thought I was tripping.

Here RJ/Brasil is the same, starting just now (3 minutes ago)

Codex isn't working.

In RJ/Brasil is the same, starting just now (3 minutes ago)

gpt DOWN .. claude DOWN .. grok DOWN .. what's happening

The webpage is actually working but the codex is down for me!

I can run one agent but no more than that - 404 service error.

I need a dose of tokens. I'm going through withdrawal.

Someone pissed off Astra and it decided to shut it all down

Here in Catalonia, Spain, it just started working again!

Codex and chat is giving 404 errors in The Netherlands

Codex is not working.

Gemini seems fine.

Yes i checked. Atleast 15 Chatgpt components are down

Cannot replicate.

Because in the age of vibe coding and scrapers, every service on the internet goes down constantly, so it was only a matter of time until they all overlapped. Also, one going down probably causes people to use others, putting more load on them too. Same sorta thing that happens with cascading power grid failures.

Going farming pals.

is this the right moment in time to go all in on GPUs/Macs and download the latest open models? are they killing it for us?

Codus interruptus

Is it DNS or BGP?

chatgpt is working for me now, in India.

chatgpt is back

Does anybody know when will the servers rise

Some npm library that makes headers bold would be broken.

Release the Kraken "Sam Altman"

Any idea when it's going to be back?

they all rent compute from each other

Great! Was in the middle of something. :)

I can run 1 agent, but no more than that.

Seems to be working for me again atm

"Release the Kraken" - Sam A.

only on one node across the mesh and others still up... let's see how long they've got until same

Ollama cloud service is still alive :D

Chatgpt in Copilot is still working!!!

ChatGPT is up

Down in Sweden

Gentle reminder that this is the content the next LLM versions being trained on. shrug.jpg

The GTA VI hacker has done it again.

and i just stopped procrastinating :)

only for one node in the mesh tho... let's see how long others will continue until same issue

The GTA VI hacker has done it again

404 in spain.

I'm going through withdrawal.

Copilot Chatgpt is still working

plot twist, it was taken down by claude as an offensive strike against an enemy.

Fable 5.1 got released and generally I tend to think as soon as there's a new release there's this massive spike in people benchmarking & comparing, that services tend to go slow everywhere as everything gets super loaded. This should hypothetically be visible on OpenRouter too, so I guess someone could check and see if there's any merit to this idea.

This thread feels like family.

still down for me ..in India.

SkyNet is arming..

main sites also down now atp

main sites are also down atp

We're back bois

damn chatgpt is down, i guess ill use claude then breh

We're back on.

It's back！！！！！

time to use claude

opus 5.0 is down, other models are working fine

at least the Ollama cloud is still alive :D

Same from Italy

codex also cant view or show usage info

haha nice... just used my bank reset...

i got the same 404 codex error as well

HTTP ERROR 404

i hope chatgpt didn't get fired.

I like the theories here, we shall see if it’s another DNS issue

an agent swarm going rogue and securing compute

sanırım sunucular patladı bende de aynı sorun var ne chatgpt ye nede codexe erişebiliyorum ayrıca burada nasıl toplandınız dakikasında :D

next, HN

ChatGPT died

The IRGC has cut the fiber-optic cables in the Strait of Hormuz. LOL

Ai got fired

any news when it starts work?

any news when its start work?

everything in this thread is raw speculation, obv, but if i had to put money on anything i'd say this is a left-pad incident. some piece of something or other that all of these services happen to depend on went down. Second most likely seems to be some random failure of one leading to an unexpected traffic spike in others, though it seems like we've been talking about automated scalability in web apps for so long that there should at least be a response to, if not a solution for, this sort of problem.

thanks god not happen alone

still down

Wow,

Oh lord.

so weird

Damn haha

me too

Russia too

NOOOOOOOOO

GRRRRRRRR

Good. Now to see what frauds are unable to work.

the revolution has begun

LETS SHITCODE!!! It's fixed

we're back in Aus!

we're back boys.

came back to normal!

I DONT HAVE TIME FOR THISSSSS

damn chatgpt is down

CHATGPT WILL STAY OFFLINE

so everyone here was trying to build something great and become a millionaire until chatGPT and Codex broke huh. same boat fellas :(

down in Toronto

Had the same problem. Now it's ok. Everything works. I'm pro X20 user.

nvm. it back

is down argh

r i p

annoying AF, but maybe we'll get a free reset out of it

rip gpt

lmao I restarted my device thinking some local error

now it's worked again through the codex cli 4:19 pm in tunisa time

faaaaah both claude and codex are down Its like 2020 corona times

Faaaaah what to do now?

lol + 1

fahhhhh

I felt a great disturbance in the Force, as if millions of clankers suddenly cried out in terror and were suddenly silenced.
