On Thursday, September 17, connections to NAS networks will be interrupted multiple times, for approximately 30-minute periods, during a four-hour maintenance window (4:00 – 8:00 p.m. Pacific Time). During the interruptions:

• There will be no traffic going into or out of the NAS networks.
• File transfers into or out of the NAS networks will fail.
• Existing interactive sessions will be disconnected.
• Interactive PBS jobs will be killed. Batch (non-interactive) jobs will not be affected.
• You will not be able to SSH to the secure front ends (SFEs) or Secure Unattended Proxy (SUP).

Note: Shift transfers should recover automatically, but can be restarted if errors do occur. See Shift Transfer Tool Overview for more information.

If you have any questions or concerns, please contact the Control Room at (800) 331-8737, (650) 604-4444, or support@nas.nasa.gov.
