Hugging Face Dataset Viewer API returns 503 Service Temporarily Unavailable

The Hugging Face Dataset Viewer API is currently returning a 503 Service Temporarily Unavailable error for all datasets. Users attempting to access the service, such as via the `datasets-server.huggingface.co` endpoint, receive an unexpected token error instead of valid JSON.

• The issue affects all datasets, including public ones like `gbharti/finance-alpaca`.
• Testing confirms the problem persists across signed-in and signed-out states, different browsers, and both desktop and mobile devices.
• The failure appears to be a service-wide outage rather than a configuration issue with specific datasets.

Users are advised to check for ongoing issues with the `datasets-server` or wait for the service to be restored.
