Ask HN: Why are OpenAI, Claude, and Grok simultaneously down? Coincidence?

    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.

    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"

      Everyone is leasing datacenter space from some of Grok, Google, and Amazon aren't they? If it's hardware or DC level disruption I'm not too surprised it can affect multiple providers.

    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.

      I thought OpenAI famously used Azure due to their partnership with Microsoft?
      • nullpoint420 25 minutes ago
        They use a lot of compute providers now, but they use Cloudflare for their networking

    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.

      It'd be funny if this is true because that'd prolly mean nobody is touching Gemini even as a fallback.
      • Insanity 43 minutes ago
        Lol I didn't even think about Gemini missing from the list. Not sure what that says about Gemini or me :)

        Just now I got this from gemini

        It looks like there's no response available for this search. Try asking something else.

          I bet they had to implement that manually to make it look like they failed too!
      • gleenn 20 minutes ago
        Google stopped putting so much money into SOTA models. All the hype has migrated. I was also frankly turned off when I got a popup from Gemein said I would either have to pay or have my conversations used for training. This may have always been true for other providers but when I declined, Gemini stopped remembering my conversations and that definitely made me move out.

          Gemini 3.8 which just came out sounds like it's very good and a great deal though.

      I find it hard to believe that enough people would flock to from Claude and Chat to Grok to cause an outage. I feel like Gemini is the dominant release valve in this case especially for enterprise.

        It’s cursor’s model so plausible, lots of folks use cursor still.
    • paxys 37 minutes ago
      Especially considering memory/gpu/compute are scarce so these services are likely running with very little buffer.

      Edit: Updated per valleyer's suggestion.

        "Domino effect" would probably be the more relevant named phenomenon there.

        This isn’t a thundering herd problem, it’s a cascading failure. (Thundering herd is about a bunch of workers waking up simultaneously)
  • Linello 43 minutes ago
    What about a hard-takeoff scenario of an unleashed OpenAI Astra taking other models down for computational resources control?
  • codazoda 1 hour ago
    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.

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

    Some npm library that makes headers bold would be broken.
    • ibejoeb 39 minutes ago
      Oh man. Some low effort supply chain attack that turns every GPU into a cryptominer. It's funny because it's plausible.
    • N_Lens 58 minutes ago
      Ah yes ye olde bold-headers: ^3.13.31;
  • Avicebron 38 minutes ago
    I suspect Azure is having issues, Microsoft has had outages the paat two days, especially with email.

    Somebody in another thread said gastown and wheelhouse automatically move to the next provider if one fails.
  • CSMastermind 1 hour ago
    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.
  • elar_verole 49 minutes ago
    Pretty sure it's a US thing since it's available here in France. What exactly is down, idk

    They all rent compute from SpaceXAI
    • lavezzi 54 minutes ago
      I don't believe OpenAI does
      • maxbaines 52 minutes ago
        My mistake, in fact it was google not OpenAI, makes sense OpenAI doesn't.
    • halcdev 1 hour ago
      Surely it's a bit more distributed than that, right?

    Seeing 503s on Gemini via API as well

    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.

    Maybe the stack behind it is down, like AWS or something
  • jedbrooke 45 minutes ago
    according to https://downdetector.com/ Gemini is down too (and copilot, but that just uses ChatGPT right?)

    The Thundering Herd has thundered, apparently.
  • satvikpendem 48 minutes ago
    They're all using Cloudflare.
  • wejick 1 hour ago
    Probably same public cloud or CDN in front of them.

    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.

    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

  • ratelimitsteve 46 minutes ago
    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.
