I believe that in AWS's statement they said that they would help them retain their data. I'm sure it just means that after midnight their S3 and RDS services are going read only until they're done taking their data out. Maybe make a final backup of their databases and put it in a bucket.
I'd be a bit more disturbed if AWS was going to remove read access after midnight.
