The SMP WU servers have been down since about noon EDT. The server status page has finally started updating again, so we can hope the SMP servers will be back up soon.
edit: It looks like the entire 171.64.65.xxx server group is down.
edit2: The server group came back up about 5:00 PM EDT. To Pegasus, yep, probably the same issue since .20, .103, and .106 serve GPU WUs.
edit3: Added "group" to edit#1 and edit#2. Added ".20" to edit#2.
