503 Service Unavailable hitting multiple major Image-to-3D Spaces (TripoSR, InstantMesh, LGM) via Gradio Client

Hello,

I am currently trying to use the gradio_client Python API to generate 3D models, but I am receiving a continuous 503 Service Unavailable error across multiple prominent, unrelated Image-to-3D spaces.

I ran a test script against the following spaces, and all of them are returning the exact same 503 Server Error:

• stabilityai/TripoSR

• TencentARC/InstantMesh

• ashawkey/LGM

• Zhengyi/CRM

Here is a snippet of the traceback I am receiving:

python

httpx.HTTPStatusError: Server error ‘503 Service Unavailable’ for url ‘https://huggingface.co/api/spaces/stabilityai/TripoSR’

Because this is affecting various different accounts and spaces simultaneously, it seems to be a broader infrastructure issue with Gradio API endpoints or Spaces serving. Is there currently a known outage affecting the API accessibility of Spaces, and is there an ETA on when it might be resolved?

Thank you!
