I'm not really sure what the right category would be, either. ;)
The submission deadlines will be the same as today, for both ICH and ACH.
While you're right that there will be some delay due to validation and processing, we have determined that the ICH will still have time for these activities after the delays introduced.
Please note: You say "error correction" which is a bit different, as that's an activity on your side. You'll be able to submit the file right up until closure (17h YMQ), and the ICH will wait until all such files have been submitted before running their processes. However, if your file has validation errors, you will have no chance to correct it until the next period. This is up to you, though.
