Topeka ? Nearly two weeks after a major state agency’s computer system failed, there is no official word on the cause.

On Tuesday, the Kansas Department of Health and Environment continued restoring systems from the crash that started Aug. 5 and ultimately affected 150 servers with 24.7 terabytes of data.

On Monday, KDHE Secretary Roderick Bremby held a news conference to talk about the situation.

Bremby asked for patience from the public and said no data had been compromised or lost.

Bremby said the problems stemmed from failure of what is called the storage area network, which is described as a central component of KDHE’s network.

By Aug. 12, a new storage area network was delivered and installed to replace one that KDHE says was three years old.

But why did the storage area network fail? KDHE said Tuesday, “Regarding the reasons for the SAN failing, we are reviewing reports now along with our vendor and consultants. We hope to have further info to release at a later date.”

At his news conference, Bremby refused to release the name of the storage area network vendor. The Lawrence Journal-World has filed a request for the company’s name under the Kansas Open Records Act.

KDHE says the system failure has not affected other state agencies, but has affected many local health departments that were unable to access data such as immunization records, the state’s disease surveillance system and child care licensing records.
