The on-campus Plesk server we run has developed an issue that requires an immediate reboot. We expect downtime to be 45 minutes to an hour. The reboot will happen at 4PM PST. We will not be able to check every site upon return of service, so if you notice an issue please open a ticket!
Update: Backup of the server took longer than expected. Extending the maintenance window until 6PM PST. If problems are noticed beyond that point in time please let us know!
Resolution: Tested cursory services in the Plesk environment and did not notice any of the previously seen issues after the reboot.
