An Azure relational database service.
If you have deleted an Azure SQL Server along with all its databases and do not have any external backups, recovery options are quite limited. According to Azure documentation, once a server is deleted, all databases associated with that server are also deleted and cannot be restored. Since you mentioned that the deletion occurred about an hour ago and that you have not recreated the SQL Server, the chances of recovery are slim.
If you had configured long-term retention (LTR) backups prior to the deletion, you could restore those backups to a different server. However, if LTR backups were not set up, there is no way to recover the deleted databases.
In summary, without external backups or LTR backups, and given that the server has been deleted, you will need to recreate the SQL Server and implement a backup strategy to avoid similar issues in the future.
