The network team is beginning additional emergency network maintenance immediately (at noon today), continuing through 7 PM this evening, to reverse changes from yesterday evening. It will have the same effect as yesterday’s outage, so you will likely lose your VPN connection and/or PACE connection at some point this afternoon during intermittent outages.

Please contact us at pace-support@oit.gatech.edu with any questions.

The GT Network team will be performing emergency maintenance on the campus firewall beginning at 8 PM tomorrow (Thursday) night, with targeted completion by 2AM Friday morning. Although every effort is being made to avoid outages, this maintenance may cause two interruptions:
  • At some point during this maintenance, users may experience up to a 20-minute interruption that will cause any open VPN connection to close. If you are connected to PACE from off-campus via the GT VPN during the interruption, you will likely lose your connection, and any terminal session, interactive job, VNC session, or running Jupyter notebook will be interrupted. Please be prepared for such an interruption when working tomorrow evening. Note that this may also interrupt any connection you have made over the GT VPN to non-PACE locations. Connections to PACE from within the campus firewalls may also be interrupted, which means that resources outside of PACE required for PACE jobs, such as queries to some software licenses used on PACE, including MATLAB or COMSOL, may be interrupted.  Batch jobs already running on PACE should not be affected.
  • In addition, about midway through the maintenance, there will be a period of approximately 20-30 minutes where authentication will be unavailable. This will prevent any new connections to the VPN, to PACE, and to any cloud service that authenticates using GT credentials.  It is also possible for this interruption to cause new job starts to fail due to the loss of access to the authentication service.

We will alert you if there is any change of plans for this emergency maintenance.

Please contact us at pace-support@oit.gatech.edu with any questions.
