How to download historical Landsat 8/9 Collection 2 Level-1 products when DDS bundles are unavailable?

[zyynwsty20031015-debug]

Hi,

I need to download original Landsat 8/9 Collection 2 Level-1 products acquired in 2025, including all bands, QA files, and metadata.

Example product:
LC08_L1TP_119028_20250415_20250424_02_T1

My workflow uses EODAG for authentication, the Python usgs package to request download URLs, and custom requests code for file transfers. I am not sure whether this is an EODAG issue or an upstream USGS issue.

On September 11, 2026, I observed:

1. Recent products still download through dds.cr.usgs.gov.
2. For the historical products I checked, M2M reports dds_ms as unavailable, while individual files and ls_zip are available.
3. Historical download URLs are successfully generated and point to landsatlook.usgs.gov.
4. Requests to that host fail because its SSL certificate has expired.
5. A limited test temporarily bypassing certificate verification for the file endpoint returned HTTP 502: “CloudFront wasn't able to connect to the origin.”
6. Chrome also displays NET::ERR_CERT_DATE_INVALID when attempting a historical download through EarthExplorer.

What is the recommended EODAG workflow for downloading all original files of historical Landsat Level-1 scenes when DDS bundles are unavailable?

Is this a known USGS service issue, or is there another supported provider or endpoint I should use?

I need original Level-1 data, not previews, Level-2 products, or re-exported imagery. I do not want to permanently disable certificate verification.

Thank you for your help!

Hi @zyynwsty20031015-debug ,

concerning the SSL certificate error, there might have be a temporary issue on their server that seems to be solved now.

Regarding LC08_L1TP_119028_20250415_20250424_02_T1 search & download, the following code works well in my workspace using eodag v4.8.0:

from eodag import EODataAccessGateway, setup_logging
setup_logging(3)
dag = EODataAccessGateway()
results = dag. search(
    provider="usgs",
    collection="LANDSAT_C2L1",
    id="LC08_L1TP_119028_20250415_20250424_02_T1"
)
path = results[0].download()

If you still have an issue, could you please tell me the version of EODAG you are using, and post the logs you get (with maximum logging, e.g. with setup_logging(3) or with -vvv through CLI).
Thanks.
