> The community hosts the data

This is the key thing for me, so there are no guarantees of the data being available? Or is all the data backed by an owner hosted box (and backups)?

The main goal is to facilitate distribution. We work with research groups and provide "best effort" hosting with the resources from our sponsors. We expect the uploader has a backup of the data in all cases.
