SCS Email Delays
DATE: 8/27/2025
TIME: 2:45 PM
SERVICES AFFECTED: Email to CS.CMU.EDU Addresses
DETAILS:
Following a report of delays and bounces for email to CS.CMU.EDU email addresses, we identified a flood of automated messages coming from an external service provider. Once the source of the traffic was confirmed, we engaged with the service subscriber to end the traffic flood. The bulk of the messages stopped coming in at 4:05 PM and related traffic was last observed at 6:39 PM.
We believe incoming email to CS.CMU.EDU addresses is functioning normally now but are continuing to monitor the service with a higher level of attention.
Note: This incident did NOT impact delivery to ANDREW.CMU.EDU email addresses.
