The mainstream support for SQL Server 2008 and SQL Server 2008 R2 has ended as of July 8th 2014. Also, the product team is working on releasing a final service pack for SQL Server 2008/R2 (SP3) after the mainstream support ends. This means, services that will be upgraded to SP3 after SP3 is released will continue to receive MS-Support for the duration of one more year and after which the support will end.

Note: if you have no plans of upgrading to SQL Server 2014 for the next few months and in the meanwhile you encounter any critical issues with SQL Server that requires support from Microsoft Customer Support, please contact http://support.microsoft.com
