Not sure WHERE they really store their data from all of us, but they should have backups.
It's on the Amazon AWS servers AFAIK. (Which is unsurprising given how ubiquitous AWS is, along with Azure and one or two others. I'm not sure that many comparable businesses would be running their own servers these days for a cloud platform with worldwide coverage.) So any transient issue could be associated with access to your 'local' AWS servers rather than anything happening at Davis, although equally Davis could eg be running an update.
