can anybody explain what main difference between two almost identical directories:
http://sentinel-s2-l1c.s3-website.eu-central-1.amazonaws.com/#tiles/22/K/EC/2017/10/10/0/
http://sentinel-s2-l1c.s3-website.eu-central-1.amazonaws.com/#tiles/22/K/EC/2017/10/10/1/
These directories almost identical, but one contains preview and another does not.
It was indeed an ingestion error, caused by Sentinel-2B products appearing on both pre-operations hub and the open data hub. The directories indeed contain identical products. We have fixed the error and removed the duplicate tile from the bucket.
The list of removed items is available at http://sentinel-s2-l1c.s3.amazonaws.com/deleted-tiles.txt
Thanks for spotting this and letting us know.
EDIT: Added link to the list of deleted items.
