We accidentally deleted our production server for Azure SQL database (the server, not just a database). How do we recover the server?
Yes, but you need to open a support ticket - upper right-hand corner in the Azure Portal.
I've no idea how you deleted the production server, but when you try to delete in the azure portal, it will remind you that deleting server is irreversible and all the items will gone permanently. So unfortunate that you cannot recover it.
In the Management Portal ( http://manage.windowsazure.com ) select the SQL Databases task on the left, and Deleted Databases on the top.
