grok4-fast-non-reasoning: persistent 503 errors?

I have two identical (afaict) deployments: grok-4-fast-reasoning, and grok-4-fast-non-reasoning. The first works, the second doesn't. Same result whether using the playground, curl, the python SDK, etc. Same result even if I try new deployments of grok-4-fast-non-reasoning.

Is it down for everyone else, or just me?
