Are your index statistics up to date? The SQL Server database engine uses statistics to determine which execution plan to use when a query is compiled. Index statistics are used to help the SQL Server engine determine the cardinality of different column values in a SQL Server table. If you want to give SQL Server a fighting chance at picking an optimal execution plan then you need to make sure you maintain your index statistics.

It is never a good idea to let your users be the ones to tell you of database server outages.
