full description of the problem from the head of IT:
The primary data store, the storage array which supports all the production requirements, experienced a fatal hardware failure at approximately 12:04 PM. It attempted to re-boot itself, which attempt failed. That left the web site completely out of service. We went to the data center and activated the "hot spare" filer, which assumed the processing load and brought the site back to life. No data was lost, and processing was restored at approximately 1:30PM. The bulk of the elapsed time was the hour that it takes to drive to Sunnyvale, where the data center is located.
