This failover is not completely seemless as the current sessions will first be disconnected and then must be reconnected. If the fail occurs during a transaction, that transaction is then rolled back.

In addition there is inbuilt DOS protection, if there are many failed attempts to access a SQL Azure database the requesting IP is disallowed for a period of time. Thus if you make several incorrect login attempts you may be locked out for a short period.
