Delay in Attachment Scanning by ATP Service

Emails that were quarantined due to this issue have been re-scanned prior to delivery. The incident is resolved.

We are re-scanning the messages that were quarantined due to this issue. Messages that do not appear to be malicious will be delivered. If messages were manually delivered, some destination mail systems may show duplicate messages.

A small number of emails were quarantined due to an inconclusive scan. We are investigating options to re-scan emails that were quarantined during the temporary delay in attachment scanning. Messages can be manually delivered by following the documentation steps listed under "Determine Whether to Deliver Message" here: https://campus.barracuda.com/doc/167976633/

A fix has been implemented and we are monitoring the results.

The issue has been identified and a fix is being implemented.

We’re currently experiencing delays in our Advanced Threat Protection (ATP) service when scanning email attachments. As a result, some emails may be temporarily deferred with the status: “Pending Scan.”

Our engineering team is actively investigating the root cause and working to restore normal scan times as quickly as possible. We’ll continue to provide updates as we make progress.

We appreciate your patience and understanding.
