Dear ECMWF/CDS Support Team,

```auto
   I am using the CDS API to download ERA5 hourly single-level reanalysis data for a research project.

```

My API requests now return the following error:

> User is disabled  
> Error id: ba7f6aaf-5dd0-4a70-ab73-e487f303a74c  
> 403 Client Error: Forbidden  
> User is disabled. Please contact the administrator.

```auto
I believe my account was flagged because I was running a Python script that downloaded monthly ERA5 data with 11 variables per request and up to two concurrent monthly requests.

```

```auto
I have stopped the automated downloads and will adjust the script to submit requests strictly sequentially and comply with the CDS service limits.

```

```auto
Could you please review my account status and advise whether my CDS access can be reactivated?

```

```auto
I would also appreciate any guidance on the applicable request limits and recommended download practices.

```

Thank you for your assistance.

Best regards,

majuntao
