At 6 AM this morning, a reload of the core switch caused a failure of the network interfaces on the Cascade Web server. This in turn caused the Cascade web interface to be unavailable from 6 to 8:15 this morning. The server was rebooted and recovered, restoring service at approximately 8:15.
Other affected servers were grace, camano, and crystal, all of which were rebooted to restore service at 7:30 AM. Batch job processing was affected between 6 and 7:30 AM.
