Deploys are getting stuck with just a "Creating deploy upload records" message

I’m also getting these a LOT since some time. Was anything changed? I’m also uploading directly through the API and retrying all 429 (getting a lot of 429s). What should a well behaved client do other than retry?

And is it the correct behavior that the deploy just gets stuck at “uploading”?

Here is a thread with more info: API Uploads (files only): Deploys get stuck in state: "uploading"
