A Brief Network Interruption Occurred at 16:49 on Friday (05-NOV)
It appears that work in or near the datacenter caused power to one of our core switches to be interrupted at 16:49. That switch rebooted and returned to service at 16:52, but the interruption disrupted our network fabric, causing processes (or jobs) using /projectsp, /home, /opt/sw, or /projects (the one with the symlinks) to be momentarily interrupted.
The problem has been resolved, but some users (or some jobs) may have noticed an interruption in filesystem activity at that time.
Please let me know if you have questions.
