[Data Missing] HTTP 404 for Interferograms on multiple Track 143A frames (Altai region)

[AmazonCc]

Hi COMET team,

First of all, thank you for providing and maintaining such an invaluable dataset.

I have been trying to download the ascending data for this region, but I found that the core time-series data seems to be missing on the JASMIN server.

When using LiCSBAS01_get_geotiff.py in my Jupyter Notebook/Colab environment, the script gets stuck in a retry loop. By printing the underlying logs, I noticed it throws HTTP 404 Not Found errors specifically when trying to access the Interferograms/ directories.

The affected adjacent frames on Track 143A are:

• 143A_04367_151415
• 143A_04140_141515
• 143A_04590_141514

The basic metadata, DEM, and average velocity maps (e.g., .geo.vlos_eur.tif) are successfully downloaded, which indicates the URLs are correct, but the actual time-series unwrapped phases/coherence files are missing from the server. Descending tracks in the same region work perfectly fine.

Could you please check the server status for these frames and see if it's possible to re-upload or re-process them?

Thank you very much for your time and assistance!

hi. many thanks for reporting this!
there is a long story related to an accident at our storage provider causing temporary loss of data from orbits 143 and two other orbits in November 2025. We were told all data were restored, but obviously not for those listed frames.
I passed the information further, and will update here once I get any new information. Apologies for the inconvenience.
