SQL Azure SLA

SQL Azure customers will have connectivity between the database and our Internet gateway. SQL Azure will maintain a “Monthly Availability” of 99.9% during a calendar month. “Monthly Availability Percentage” for a specific customer database is the ratio of the time the database was available to customer to the total time in a month. Time is measured in 5-minute intervals in a 30-day monthly cycle. Availability is always calculated for a full month. An interval is marked as unavailable if the customer’s attempts to connect to a database are rejected by the SQL Azure gateway.
