For Critical Support Requests after Normal Support Hours
Calls to SAS Technical Support for critical requests after normal support hours are directed to one of the SAS worldwide support centers in North America, Europe, or Asia/Pacific, thus providing 24-hour, follow-the-sun support. Customers can update tracks electronically 24x7. However, for new requests or for existing tracks with requests that become critical outside of normal business hours, customers must also call SAS Technical Support. The phone number is available on the Contact SAS Technical Support web page. When customers call, they must press 2 for Technical Support, listen to the greeting in its entirety, and then press 0 to start follow-the-sun support.
Note: After-hours support is available only in English and is limited to critical requests for software products under Standard Support. Because the support is in English, it is important that customers are able to adequately discuss their request in English. SAS provides self-help resources such as support.sas.com and the SAS Support Communities for software products under Limited Support. Customers can search these resources for potential circumventions to issues that are similar to the one that they are experiencing.
In addition, customers can access the SAS Support Site website and email support services 24 hours a day.
