We finished synchronizing user data between disk arrays overnight; we still need to sync our collection of installed software and some administrative files. That (hopefully, provided nothing goes wrong) puts us on track to restore service this afternoon or evening.
We're also taking advantage of this downtime to do some upgrading on one of our backend machines; that work has been completed. We might do some small physical reorganization of our servers and their power connections, but that's about it for the other work we're doing during this maintenance window.
Hope you're enjoying your break, and thanks for your patience!
