The Ohio Supercomputer Center (OSC) is experiencing an email delivery problem with several types of messages from MyOSC. 

OSC has conducted thorough validations to ensure the integrity of our backup data for the /fs/ess filesystem and are beginning full-scan backups of the home directories.

A bug in the trigger that sends automated emails from client portal


We deployed a new version to OSC Client Portal ( at 3 pm Tuesday, July 9th, which involves a bug in the trigger that sends automated emails to some OSC clients with the subject 'Your OSC account has had its system access changed'.

We are working to fix this bug as quickly as possible and apologize for any inconvenience.  Please contact if you have any questions.
