Gaia SIF data retrieval issue

I’m trying to retrieve the Gaia SIF/FPR data for our variable-star pipeline, specifically the `crowded_field_source` table.

I’m currently unable to connect to the Gaia TAP service.

### Reproduction

Running:

```bash
curl -I "https://gea.esac.esa.int/tap-server/tap/availability"
```

returns:

```text
curl: (56) Recv failure: Connection reset by peer
```

I also get the same issue through `astroquery`:

```python
from astroquery.gaia import Gaia

Gaia.load_tables(only_names=True)
```

Output:

```text
INFO: Retrieving tables... [astroquery.utils.tap.core]
Remote end closed connection without response
```

The intended query is:

```sql
SELECT TOP 10 *
FROM gaiadr3.crowded_field_source
```

But the connection fails before the query can be executed.

```

http.client.RemoteDisconnected: Remote end closed connection without response
```

Could someone confirm if the Gaia TAP service is currently accessible and whether `crowded_field_source` can be queried programmatically?

Start by running the reported curl request against the Gaia TAP availability endpoint and then reproduce the failure with astroquery.gaia.Gaia.load_tables(only_names=True). Check whether the service is reachable and whether the stated gaiadr3.crowded_field_source query works programmatically; done means documenting confirmed availability or a reproducible project-side failure.
