Dear NERSC Users, NERSC and HPE engineers successfully found the root cause of the network issues that you encountered yesterday (1/26). We will be monitoring the system over the next several days to determine whether the mitigations we deployed during the last maintenance are sufficient to prevent further widespread network issues. We appreciate your patience as we all develop our troubleshooting skills with and our understanding of Perlmutter's novel network architecture.
