This seems to have resolved now. We're monitoring this actively.

We're seeing reports of this on the OpenAI community - https://community.openai.com/t/partial-outage-across-chatgpt-and-the-api/481471/6?u=codehex

We're noticing a high error rate (429s) across a few accounts using Portkey. We're in touch with OpenAI and trying to remedy the situation.
