These connection problems can be caused by Azure SQL Database reconfiguration, firewall settings, a connection timeout, incorrect login information or failure to apply best practices and design guidelines during the [application design] (sql-database-develop-overview.md) process.

Most reconfiguration events are generally short-lived and should be completed in less than 60 seconds at most. However, these events can occasionally take longer to finish, such as when a large transaction causes a long-running recovery. The following table lists various tranisent errors that applications can receive when connecting to SQL Database
