I had not understood everything on the issue Sentinel-2 had in October and November with its image processing and storage systems (the MMFU system). The bug has been identified but the correction has not been uploaded yet. It seems that it took quite some time to test it and have it work in all cases. The correction routine seems to be ready now and should be uploaded this week.Meanwhile, Sentinel-2 has been suffering from new data gaps, which should come to an end after the patch is uploaded. For instance, if you look at what is available on Toulouse, you'll find no image between the 10th of December and today, 15th of December. But the acquisitions resumed on the 16th of December.
