- On Oct. 11, for 1 hour and 47 minutes, multiple users in one facility were unable to access the network.

"The dedication of this organization is to quality outputs and system availability," said Henry Neidermeier, vice president and quality leader for KP-IT. "The complexity of the challenge here, with the links in the availability chain, is significant."

Kaiser spokesman Matthew Schiffgens said any issues that have come up should not be surprising, given the complexity of the project. He acknowledged that a report had been compiled to track problems.

"As you move out with a very large deployment like this, you encounter challenges along the way, and we have a process to systematically identify and address challenges as they arise," Schiffgens said. "The problem at the Corona data center was a good one. It came up, we addressed it, and we feel confident that we made the proper infrastructure to manage that. That is the fundamental practice of running a good business. Does that mean there are systematic and ongoing problems? No. You identify issues and address them as they go along. You're seeing a robust process in terms of those reports."

Neidermeier said Kaiser is focused on managing the problems detailed in the report and working to make sure it has backup procedures in place so that patient care isn't compromised.
