2023-12-07 Remediation delayed for IES and AMB
Incident Report for Abnormal Security
Resolved
TLDR: Due to a large spike in detected attacker activity, a subset of our backend systems are experiencing extremely high load, which is resulting in delayed message movement starting at 00:00 UTC on December 08, 2024, impacting IES and AMB. Messages are being judged correctly, but movement to the appropriate remediation folder is delayed during the incident timeline.

Affected Services: Inbound Email Protection and Abuse Mailbox
Severity Level: Major
Incident Start Time: December 08, 2023, 00:00 UTC
Timeline:
09:00 UTC: Processing for messages that were delayed during the incident timeline from 00:00 - 02:15 UTC is complete. The incident is now fully resolved.
02:15 UTC: Live processing for message remediation has recovered for all customers going forward.
01:55 UTC Other required backend services required to ensure message remediation success are healthy. The team is increasing traffic volume to the relevant backend systems to regular message processing volume.
01:45 UTC Database used to ensure message remediation success is healthy. The team is restoring regular message processing traffic volume to the relevant backend systems.
00:30 UTC: Identified the source of high attacker activity
00:00 UTC: Message remediation starts being delayed for IES and AMB
