In an effort to address any lingering issues with our network hardware, we will be performing a staggered reboot of two network gateway devices. These devices redundantly link portions of the HPCF environments to each other and to the main campus. The staggering of the reboots should eliminate the possibility of a loss of network connection.

If you notice any connection issue in the next 1.5 hours, please be aware that a failure in this redundancy might be to blame. 

If this connection issue persists, please submit a descriptive RT ticket to: https://doit.umbc.edu/request-tracker-rt/doit-research-computing/  

Please let us know if you have any questions about this.

Thank you for your understanding,
Roy Prouty
System Administrator, UMBC HPCF
