Is the fine tuning servers down again?

Hello, We’ve confirmed that this is affecting some fine-tuning jobs waiting in queue, including jobs on gpt-4.1-mini. The jobs are being accepted and validated, but some are taking longer than usual to start training due to elevated queue volume. We’ve increased processing throughput and expect the queue to clear gradually over the next several hours, though some jobs may still take up to 24 hours. For large training files, it’s best to keep one validated job queued rather than repeatedly cancelling and recreating it.
