In response to recent service interruption that occurred on Wed March 7th, Qualys operations is undertaking an immediate update to the Oracle database for the QualysGuard US infrastructure. This update will fix Oracle bug #7307972*.

This emergency upgrade requires an 4-hour downtime starting on March 21, 2012 at 16:00 PDT (23:00 GMT). The following services will be unavailable at this time:


For subscriptions not using QualysGuard New Scanner Services, any scans running at the start of the scheduled downtime will be canceled and any scans scheduled to begin during the downtime will start immediately following the scheduled downtime. Customers are advised to make sure that the re-start of scheduled scans after the downtime does not interfere with normal network operations.


Scanning for subscriptions using New Scanner Services will not be affected. 


To find out if your Scanner Appliances are using New Scanner Services, please check their status within the Scans->Appliances tab in your QualysGuard subsription.
