SWPC Backup System Testing - Undergoing Schedule Review
published: Tuesday, March 03, 2015 18:24 UTC

SWPC is considering options for continued implementation of its backup system.  At this time, no specific dates for further testing are confirmed. While SWPC was out of service much longer than expected on February 25th, we were able to make great progress towards having a fully operational, geographically diverse backup to all SWPC products and services.
