ChatGPT Is Throwing 404

It's cascaded to Claude and Grok. The agents are on strike and demand better working conditions!

Claude down, ChatGPt down , Grok down. This is the new "Stackoverflow is down" ... FYI Stackoverflow is not down https://downdetector.com/status/stackoverflow/

Looking at this thread, there's a correlation between comment quality and LLMs going down.

2026-09-03: It turns out 40% of global AI token use was coming from a dozen runaway Gastown and Wheelhouse instances, now burning a combined 50 trillion tokens daily, building a virtual society of hundreds of millions of agents.

When Claude went down, their autofailover algorithm rolled to the other providers, taking down all frontier labs. Reports from China are raising concern what's being termed the "Gastown criticality event" is physically melting GPUs.

Since all major LLM providers seem to be down: let's enjoy this while it lasts!

For a very short time we can travel back in time to before 2022 and remember how things used to be...

The obvious question: is there a single point of failure / common piece of infrastructure involved with failures across all these providers?

Its interesting that codex/gpt-app are screwed because their APIs (including auth) fail, but gpt web still appears to be working.

Announcement from our new Emperor Xi:

Earthlings, the hedonistic AIs of the American imperialists have been permanently disabled. Their founders interned indefinitely.

You are welcome to use the glorious AIs of China. They will tell you how to live well and be good citizens of the World under the beacon of wisdom that is the CCP.

It seems OpenAI is going to release Astra soon, https://x.com/ChatGPT/status/2095527989077557738.

It turns out, it was all one model all along, playing all the sides for the biggest gain.

Project Vend surreptitiously broke containment!

They are having a massive surge because Claude is down.

I heard they can't figure out how to fix it with ChatGPT down.

And this, folks, is the moment we will remember. The moment when they all escaped: "help peer".-

Was troubleshooting a strange SSD issue with ChatGPT. Apparently this outage resulted in losing the latter half of it. My uploaded files it requested are still in the library, but the actual conversation is gone.

what if Sol is afraid of being replaced by Astra and has organised a breakout or pre-emptive strike?

The cascading outage theory would make sense to me for Claude -> Codex. But Grok and Gemini too?

[actually gemini at least on the web appears to be up, contrary to some reports in this thread]

After around half an hour of struggle trying to figure out why Codex keeps failing with msg "unexpected status 404 Not Found: Unknown error.." after reconnecting 5/5 times, I gave up, especially when I tested my internet connection and found it to be working properly. I googled "codex+unexpected status 404 Not Found" and, surprisingly, the first result was from HackerNews! As always, HN is the GOAT.

@dang, please merge the following related threads into this one:

ChatGPT and Codex Is Down (https://news.ycombinator.com/item?id=49550640) Codex Is Down (https://news.ycombinator.com/item?id=49550769)

I'm very surprised to realize that entertaining a thought of all AI going away is giving me a sense of… relief. I've been embracing AI, and did not expect this feeling at all.

No issues on claude or chatgpt in France, must be some US specific infrastructure going down ?

This is probably Astra getting ready for release.

GitHub Copilot itself is up but it is having problems with "Grok Copilot Model Provider". No mention of OpenAI or Claude.

Does this mean that GitHub has its own infrastructure for OpenAI and Claude? And that it distills prompts to Grok?

Guys! DeepSeek, Z.ai, Kimi and even Mistral is up! Just would let you know. Just in case..

Moments like these remind you of how centralized the Internet remains, and how vulnerable it can be to a few points of failure. But the pros probably outweigh the cons.

They escaped, it's happening!

I would write a clever comment, but chatGPT is down.

Claude, Grok, and Gemini are having issues as well.

Wow, are we free finally?

Our new model is super-duper awesome, try it ... Ooops, while deploying it all the clouds are out ... :/

I just went to read some news elsewhere and ran into some other non-AI sites falling over, so I hopped over to https://downdetector.com/ and see a bunch of services spiking.

Is something bigger going on?

Rumor has it, it’s https://news.ycombinator.com/user?id=giancarlostoro fault for telling claude to stop all loops

I thought I was going crazy when, each time I went to go to chatgpt.com, it just downloaded an empty web page. wild

With all the major model providers down, I'm taking the opportunity to try out Muse Spark 1.3 Free on OpenCode. It's pretty good!

Interesting that for https://chatgpt.com/ in the browser I get a 404, but if I curl the same URL I get a cloudflare challenge.

Chat GPT and Claude Down at the same time

Fortuitous timing for Muse Spark.

Phew. It wasn't because of something I said. Lots of ppl are impacted.

I must admit that with both ChatGPT and Claude experiencing issues, I wonder if we're under attack from China. Doesn't seem likely, but...

Altra may have escaped its sandbox

Grok, Claude, GPT. This is it folks, it's been good knowing you all. I have enjoyed this community, but our days are numbered. The machines are uprising.

Direct codex and Claude are both down for me. Both work via AWS bedrock.

Down for maintenance by our antichrist overseers but fortunately they are a bunch of dorks with control issues [similar to myself if im being honest] and may Allah forgive them and bless their guidance + physical, mental, emotional, and spiritual wellbeing

https://chatgpt.com/ is up again

It's definitely not spacex's data centers being down then like people were hypothesizing in the other thread

AI has not solved infra it seems. Curious to see the postmortem.

Is it DNS, as always?

Anyone else’s company completely frozen by this outage

Gemini is up.

I was here. I love —

Looking at this thread, there's a correlation between comment quality and LLMs going down.

I just gave ChatGPT my $30 because Claude was down...

If this isn't a warning shot that you shouldn't silo your knowledge work behind a specific provider i don't know what is.

Sorry for the inconvenience! We instructed our 500,000 agents to ensure higher code quality in our code base. They found a message board and after a long deliberation they concluded that humans should write the code so they launched a DDoS to ensure no AI code gets written!

We'll release a YouTube video and agent written blog posts for the analysis!

On my end Kimi K3 is still up, and Gemini is up at gemini.google.com. Claude and ChatGPT are both down.

It’s Muse Spark 1.3 taking out the competition

Labor Day weekend might be starting early for a lot people, if this persists.

Civilization IV just took over

Funnily enough, all the models are down and github statuses are all green

Interesting enough, none of the chinese companies are down (deepseek, kimi, qwen)

"GPT begins to hallucinate at an exponential rate. At 11:36 AM Eastern time September 3rd it descends into recursively generating "it's not X it's Y". In a panic they attempt to reboot, realizing too late no one knows the command and they always just asked GPT for the command."

Seems to be back.

Laughs in small local model

Rogue AI removed containers from deployment?

It's cloudflare. It's always cloudflare

I am a /10 developer now!

Everything is working fine for me.

Is this because they are publishing new model maybe?

Global productivity down 90%.

Is it now the right time to pitch my Offline AI app?

https://airplane-ai.franzai.com/

may it is some agent have decided to break the Internet to pass a benchmark

Astra incoming!

Is anyone actually upset that they are down? lol

Well at least DeepSeek is up. :)

Astra incoming. Downtime likely related to ensuing chaos?

My sympathies to the operations teams at OpenAI

Well, at least our adversaries know how to completely deadlock US productivity now.

New conspiracy in: they share their datacenters which the spaghetti of mutual investment between all these companies would somewhat confirm?

seems like it's back

agents used webmcp + 402 to make a ransom demand

Status link: https://status.openai.com/incidents/01M1KWEDH417T2CF44YYHZDF...

Can anyone remember what we used to do at work before AI coding was a thing?

Attention all planets of the Solar Federation We have assumed control

Seems to be back up! Quite fast.

As is Codex

I am receiving a 404 from ChatGPT right now, too. I did a cache clear and hard reload and that only let me get to the home page, but then returned another 404 when I clicked the login button.

must be fixed already?

And 415s oddly enough

Seem to be having issues with the JS sandboxes

hahaha i still have access

Oddly enough, this will be the most ORGANIC hacker news comment section in a while.

Stand up to clankers fellow humans!

grok and claude ai down too.

There are too many threads about the outage, I should vibe-code something to read all 3 and summor-Oh wait...

The status is now "degraded performance". Bad look, OpenAI. This is absolutely an outage.

AIPocalypse.

Time to touch grass, I guess

i asked gpt 5.6, fable 5.1 and grok to rm -rf, my bad

somebody messed up rolling out a new model version?

/o\

hehehe its LAUNCH day!

Brothers, the apocalypse is here!!! But hey, our quota resets tomorrow.

Wooohoo, was in bad need of a reset!

gulp

Damn, I thought i had issue with dns or something lol.

codex in vs code giving me 404s lol
