Due to issues with the department’s LDAP directory, lists.eecs stopped processing messages around 10:57am. Once the ldap server was restarted, lists.eecs was restarted around 2:28pm.
By around 3pm, all queued messages seem to have been delivered.
Backup plans are being put in place to manually recover from future LDAP outages.
