There is a decent chance that this product is actually corrupted at source, so there is not much we can do about it.

I suggest you first check at Source and if you see the issue there, report it there.

Note that there is currently a reprocessing campaign going on, so all these products will be replaced eventually, in coming months.

About reprocessing, is there any news about it and the replication of Collection 1 products to AWS?

The reprocessed data are replicated to AWS, but at slow speed (due to bandwidth limitations of the source).

Nice to hear that, will there be a notification when the collection is available?

The products are ingested as we speak, in the main (and only) bucket.
