Postmortem - Read details
Aug 22, 17:37 UTC
Resolved - We have re-processed the 5000 failed submissions from this incident.

Most submissions should have been successfully re-processed and you will have received a submission email confirming this. However, if you made a deposit with the same data and a newer time stamp, you will have received a submission email with a message that the timestamp is incorrect. You can ignore this as your newer submission will still be there.

If your deposit contained an entirely separate error, you will have received a submission email with the relevant error message - please deal with this in your usual way.
Aug 22, 16:36 UTC
Update - We're about to start re-processing the 5000 failed submissions from this incident.

Most submissions should be successfully re-processed and you'll receive a submission email confirming this. However, if you've made a deposit with the same data and a newer time stamp in the meantime, you'll receive a submission email with a message that the timestamp is incorrect. You can ignore this as your newer submission will still be there.
If your deposit contained an entirely separate error, you'll receive a submission email with the relevant error message - please deal with this in your usual way.
