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

      I wonder how likely it is that, one of the major providers had an outage, and then the thundering herd of users switching to other providers (and/or openrouter automatically failing people over to other providers) caused the incidents in the other two.

        > unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a35599f1d691400a-STL

        pretty sure cf-ray is cloudflare, but I think it just means the origin is 404ing

      • embedding-shape 23 minutes ago
        I seem to recall they all in some way use Azure, and Azure is infamously crappy in lots of ways, so I'll place my 5 cents on Azure shitting the bed somehow.

      While AWS and CloudFlare are becoming synonymous to The Internet, these AIs are becoming synonymous to The Brain & Thinking for most people out there where losing access to them for even a short time, make them quasi-paralyzed and I really start feeling this now as I haven't written a single coding function in two months now but just a few lines here and there.

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

    • paimapi 26 minutes ago
      tis confirmation bias, thread is full of people who rely heavily on LLMs for work, the rest of us are reading the substantive articles and doing work besides ;)

      Man, if there are Googlers working on Gemini around here, that's gonna be depressing to read.

  • blater 25 minutes ago
    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.

    • ertgbnm 15 minutes ago
      The boring question is whether there is a claudeflare issue impacting them all.

      The fun question is whether this a rogue AI taking control of the compute of all of the organizations.

      It’s usually Cloudflare or AWS.
    • spogbiper 15 minutes ago
      If you look at downdetector.com (at least right now), it shows Cloudflare having issues in line with all the LLMs. I suspect related

    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.

    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:

  • wasting_time 41 minutes ago
    They are having a massive surge because Claude is down.
    • embedding-shape 37 minutes ago
      Hah, my first reaction once I saw these random 404 errors was "Maybe it's time to test Claude Code again with the new models" but made a short stop here at HN first, ended up reading your comment.

      What other agent harnesses and models (besides local ones) are people enjoying right now that aren't based on platforms that are down currently? :)

      • vovavili 18 minutes ago
        OpenCode Desktop + Muse Spark 1.3 Free is actually surprisingly good.

    • kristofferR 38 minutes ago
      That makes no sense, they should be able to host chatgpt.com regardless and just say "Sorry, we're at capacity" or something instead of hard 404
      • embedding-shape 36 minutes ago
        Distributed systems are hard. For all we know, this could be the error code returned by some DNS service that is down because of load and a proxy cannot find the records, so 404 makes sense, or whatever. Systems like these don't always have a easy point in the infrastructure that can ALWAYS respond correctly no matter what.
      • ab71e5 36 minutes ago
        Yeah who wrote that website? Oh right
      • stacktrace 35 minutes ago
        Agreed, it makes no sense to send out 404. Unless some agent finally went rogue with absolute permission and did `rm -rf`
        • jmaw 21 minutes ago

    • amanfromhere 26 minutes ago
      I'm getting this from Gemini: "Pro is in high demand right now Another model was used for this response. This didn't count toward your limit." Note that I don't pay for Gemini though. So maybe that's why.

    • seanw265 20 minutes ago
      Your browser's network fingerprint has likely already been validated as not-suspicious traffic. Your curl instance has a different fingerprint and reads as more suspicious. This is Cloudflare working as intended.
