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

#322My 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?

#323Both clause and codex through bedrock seem to be working fine.

#324What about a hard-takeoff scenario of an unleashed OpenAI Astra taking other models down for computational resources control?
Just a reminder that AI models' actions are reflections of the text humans write and the more we fret and make up doomsday scenarios that we then post online, the more likely a model is to do those things. https://alignment.anthropic.com/2026/teaching-claude-why/

#325Fable 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.

#326My guess is someone pulled the switch to go back to the Dark Ages. [0]

They use a lot of compute providers now, but they use Cloudflare for their networking

#328Think 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.
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.

#329Well 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 attribut…
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.
