We have not.
Actually, we've had the opposite. For example, during Hurricane Katrina when our hospital in New Orleans was evacuated, we took the backup tapes from the computer system and, within 24 hours, moved them to the Houston facility and had that information back up and online available for those veterans wherever they showed up. If they had a dialysis treatment on Monday, by Wednesday they were back online and their information was available. That has been our experience.
We had an experience about a year and a half ago where we had 17 systems on the same regional data processing system that went down. Providers did have access to read-only information, but they were down for about 17 hours, and there have been contingencies put in place since then that after five hours of downtime they would actually be reverted to a backup system. We're putting a lot of redundancy in place to make sure we don't have single points of failure for these systems.
